(1.16.1).setLightLevel and .setRequiresTool gives error Cannot resolve method 'setLightLevel' in 'Properties'

Recommended Posts

I just moved my 1.15.2 mod to 1.16.1 by replacing the build.gradle with a 1.16.1 build.gradle from the 1.16.1 mdk. I then recreated the workspace. For some reason though, the .set commands dont work and I get an error saying:Cannot resolve method 'setLightLevel' in 'Properties'

 

 

My Code:

package com.Michael.TutorialMod2.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.SoundType;
import net.minecraft.block.material.Material;
import net.minecraftforge.common.ToolType;

public class RubyBlock extends Block {


    public RubyBlock() {
        super(Block.Properties.create(Material.IRON)
        .hardnessAndResistance(5.0f,6.0f)
                        .sound(SoundType.METAL)
                .harvestLevel(3)
                .harvestTool(ToolType.PICKAXE)
                .setLightLevel(value ->1)
        );
    }
}

Hi

Every time the Minecraft version updates, there are a lot of changes to functions; sometimes it's just the names, other times the signatures changes, and sometimes whole classes and groups of classes are refactored to work differently.

 

The best way to fix these problems during an update is 

1) Find a vanilla class that uses the method in (eg) 1.15.2

2) Find the same vanilla class in 1.16.3, browse through the code until you find the code that calls the same method and see what it has changed to.

 

90% of the time you'll find it within a minute.

I figured it out. My mappings were out of date. i was in 20200543.1.16 but I should have been in 20200723.1.16.1 

For anyone that has the same problem as me and comes across this forum, you can change the mapping version by going to the build.gradle file in your forge mdk and it will be around line 29.

what is an srg name?

Every class, method, field, parameter, and local variable has 4 names:

 

  1. Notch Names (these are what the game is originally programmed in). We do not have these for most things, Mojang is (supposedly?) publishing a deobf map, but I don't think it is in use by Forge yet.
  2. Obfuscated Names (these are what you would see if you opened Minecraft's source in a decompiler). a, aa, ab, abb, etc. It is unreadable.
  3. SRG Names (these are the first step in deobfuscation, machine translation from the obfuscated source to a consistent mapping). Not human readable, but the same method will always deobf to the same SRG name even as things change and get new Obfuscated names.
  4. MCP Names (these are the human readable ones). These take time and constant effort to map.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

This is not quite correct. Notch names are the obfuscated names. The names that Mojang uses in their source code are sometimes called "official".

I never had issues with this before, but I guess the mappings that come with the MDK download are out of date? Didn't know we had to manually change them when downloading the MDK I guess that's new also on 1.16. Or is there a reason the "Recommended" version doesn't update this value?

 

My 1.16.3 download (forge-1.16.3-34.1.0-mdk) had on mappings

 

mappings channel: 'snapshot', version: '20200514-1.16'

 

Where you got the 20200723.1.16.1 from? So I can got get the corresponding for the 1.16.3- 34.1.0 version.

 

Thanks a lot.

    • Catch up with the last topic with rendering, this is something that I took a while to learn from nothing to this stage. (I only shoot from right side) public static List<Pair<BlockRayTraceResult, Float>> rayTraceAndPenetrateBlocks4(World world, List<Vector3d> vecs, float health, Function<BlockState, Float> getHealthReduction) { List<Pair<BlockRayTraceResult, Float>> results = new ArrayList<>(); if (vecs.isEmpty()) return results; Vector3d startVec = vecs.get(0); for (int i=0;i<vecs.size()-1;i++) { Vector3d vec = vecs.get(i); Vector3d next = vecs.get(i + 1); BlockPos pos = new BlockPos(vec); BlockPos pos2 = new BlockPos(next); BlockState blockstate = world.getBlockState(pos); BlockState blockstate2 = world.getBlockState(pos2); if (blockstate.getBlock() instanceof BarrierBlock && blockstate2.getBlock() instanceof BarrierBlock) continue; VoxelShape blockShape = blockstate.getCollisionShape(world, pos, ISelectionContext.dummy()); VoxelShape blockShape2 = blockstate2.getCollisionShape(world, pos2, ISelectionContext.dummy()); BlockRayTraceResult blockResult; boolean empty = blockShape.isEmpty() || blockShape.toBoundingBoxList().stream().noneMatch((bb) -> bb.offset(pos).contains(vec)); boolean empty2 = blockShape2.isEmpty() || blockShape2.toBoundingBoxList().stream().noneMatch((bb) -> bb.offset(pos2).contains(next)); if ((isRayTraceIgnorableBlock(blockstate, blockShape) && isRayTraceIgnorableBlock(blockstate2, blockShape2))) continue; if (empty && !empty2) blockResult = world.rayTraceBlocks(vec, next, pos2, blockShape2, blockstate2); else if (!empty && empty2) blockResult = world.rayTraceBlocks(next, vec, pos, blockShape, blockstate); else blockResult = world.rayTraceBlocks(vec, next, pos, blockShape, blockstate); if (blockResult != null) { health -= getHealthReduction.apply(blockstate); results.add(new Pair<>(blockResult, (float) startVec.distanceTo(blockResult.getHitVec()))); if (health <= 0) break; } } return results; } public static List<Vector3d> getAllVectors2(Vector3d startVec, Vector3d endVec, int distance) { List<Vector3d> vecs = new ArrayList<>(); Vector3d step = endVec.subtract(startVec).normalize(); int rayTraceCount = 20; for (int i=0;i<distance;i++) for (int j=0;j<rayTraceCount;j++) vecs.add(startVec.add(step.scale(i).add(step.scale((float) j / (float) rayTraceCount)))); return vecs; } The vecs passed into the first method comes from the second method. The concept is to gather a collection of vectors, and the do ray trace between each of them. The first method can be a lot more simplified but not on my case since I also do entity penetrations, with damage calculations...etc. Anyways, if you only do normal raytracing what you will get will be something like:   Black Block represents a solid block Gray Block represents air or empty shaped block Green dots represents the positions we ray trace between. Blue dots represents the ray trace hit result. As you can see, the ray trace hit will not (unlikely) hit the surface when coming out of a block, therefore we need to detect the situation and ray trace back wards: So we get the "entering" and "exiting" points.   Here comes the rendering part once again, once you have let the client know where is hit you can perform the rendering based on the ray trace result. private static void renderObjectAt(Minecraft minecraft, EnvironmentObjectEffect object, World world, MatrixStack stack, float size, float offsetScale, ResourceLocation texture) { Vector3d vec = object.getVec(); stack.push(); Vector3d view = Minecraft.getInstance().gameRenderer.getActiveRenderInfo().getProjectedView(); double x = vec.x - view.getX(); double y = vec.y - view.getY(); double z = vec.z - view.getZ(); if (Math.sqrt(Math.pow(x, 2) + Math.pow(y, 2) + Math.pow(z, 2)) > 100.0F) return; stack.translate(x, y, z); Direction direction = object.getDirection(); if (direction != null) { Vector3i offset = direction.getDirectionVec(); stack.translate(offset.getX() * offsetScale, offset.getY() * offsetScale, offset.getZ() * offsetScale); rotateByDirection(stack, direction); } else { stack.rotate(minecraft.getRenderManager().getCameraOrientation()); stack.rotate(Vector3f.ZP.rotationDegrees(180.0F)); } if (object.doBlend()) { Color colour = new Color(world.getBlockState(object.getPos()).getMaterialColor(world, object.getPos()).colorValue); RenderSystem.color4f(colour.getRed() / 255.0F, colour.getGreen() / 255.0F, colour.getBlue() / 255.0F, object.getTransparency()); } AVAClientUtil.blit(stack, texture, -size, -size, size, size); RenderSystem.color4f(1.0F, 1.0F, 1.0f, 1.0F); stack.pop(); } direction is facing from the BlockRayTraceResult, and doBlend is true so it will look better with the block behind it. The offset is required otherwise it will be on the same level with the block, the offset scale is a small number so there will not be an obvious gap between the wall and the texture object, the scale also prevents multiple objects overlap, for example when I have multiple "renderable objects": for (EnvironmentObjectEffect bulletHole : AVACommonUtil.cap(world).getBulletHoles()) renderObjectAt(minecraft, bulletHole, world, stack, 0.075F, 0.01F, BULLET_HOLE); for (EnvironmentObjectEffect blood : AVACommonUtil.cap(world).getBloods()) renderObjectAt(minecraft, blood, world, stack, 0.525F, 0.011F, BLOOD); for (EnvironmentObjectEffect knifeHole : AVACommonUtil.cap(world).getKnifeHoles()) renderObjectAt(minecraft, knifeHole, world, stack, 0.095F, 0.0105F, KNIFE_HOLE); for (EnvironmentObjectEffect grenadeMark : AVACommonUtil.cap(world).getGrenadeMarks()) renderObjectAt(minecraft, grenadeMark, world, stack, 2.5F, 0.075F, GRENADE_MARK); bullet hole < knife hole < blood < grenade mark (level) Red Image    
    • Hi, this article is more of a experience sharing instead of a tutorial, the code themselves should be self-explanatory, and the way I do things may not be the best practice, or most efficient. Product:   I started with the textures, we need the textures/icons that are being rendered to the world, and the ones for the UI. The blue textures are used when the option is hovered. Then, we need to find out where the mouse is at and which one is selected, we can check the distance and angle from the screen center and decide which part it is on: private int getHoveringType(Minecraft minecraft) { double mX = minecraft.mouseHelper.getMouseX(); double mY = minecraft.mouseHelper.getMouseY(); double actualW = minecraft.getMainWindow().getWidth() / 2.0F; double actualH = minecraft.getMainWindow().getHeight() / 2.0F; double mX2 = mX - actualW; double mY2 = mY - actualH; double angle = AVAWeaponUtil.getAngleFromCoord(mX2, -mY2) + 30; if (Math.sqrt(mX2 * mX2 + mY2 * mY2) <= 15 * minecraft.getMainWindow().getGuiScaleFactor()) return -1; if (angle > 360 || angle <= 60) return 0; return ((int) angle / 60); } public static double getAngleFromCoord(double x, double y) { double angle; angle = abs(atan2(x, y) * 180.0D / PI); if (x < 0) angle = 360 - angle; return angle; } In this case the angle is 60 because 360 / 6 options = 60, and if the mouse is within radius of 15 from the screen center then no action is performed (-1) And then the rendering can be done. @Override public void render(Minecraft minecraft, PlayerEntity player, MatrixStack stack, IPlayerAction capability, float screenWidth, float screenHeight) { float x = screenWidth / 2.0F; float y = screenHeight / 2.0F; float size = 60; int type = getHoveringType(minecraft); AVAClientUtil.blit(stack, type == -1 ? UI_BG_LIT : UI_BG, x - size, y - size, x + size, y + size); for (int i = 0; i < 6; i++) { stack.push(); stack.translate(x, y, 0.0F); stack.rotate(Vector3f.ZP.rotationDegrees(i * 60)); stack.translate(-x, -y, 0.0F); AVAClientUtil.blit(stack, type == i ? UI_BG_2_LIT : UI_BG_2, x - size, y - size, x + size, y + size); stack.pop(); } AVAClientUtil.blit(stack, UI_BG_ICON_LAYER, x - size, y - size, x + size, y + size); } public static void blit(MatrixStack stack, @Nullable ResourceLocation texture, float x1, float y1, float x2, float y2) { if (texture != null) Minecraft.getInstance().getTextureManager().bindTexture(texture); Matrix4f matrix = stack.getLast().getMatrix(); Tessellator tessellator = Tessellator.getInstance(); BufferBuilder bufferbuilder = tessellator.getBuffer(); bufferbuilder.begin(7, DefaultVertexFormats.POSITION_TEX); bufferbuilder.pos(matrix, x1, y2, 0.0F).tex(0.0F, 1.0F).endVertex(); bufferbuilder.pos(matrix, x2, y2, 0.0F).tex(1.0F, 1.0F).endVertex(); bufferbuilder.pos(matrix, x2, y1, 0.0F).tex(1.0F, 0.0F).endVertex(); bufferbuilder.pos(matrix, x1, y1, 0.0F).tex(0.0F, 0.0F).endVertex(); tessellator.draw(); } If the type is -1, then the circle at the center use the blue texture. Otherwise if the type equals the index of the option, it uses the blue texture (or just use RenderSystem.color4f). By rotating an identical texture we don't need to have 6 different textures for each option.     public static boolean ACTIVE = false; public static Vector3d VEC = null; @Override public void tick(Minecraft minecraft, PlayerEntity player) { if (minecraft.isGameFocused() && minecraft.currentScreen == null && AVAClientConfig.ENABLE_PING_HOTKEY.get()) { if (AVAClientUtil.middleMouseDown()) { if (!ACTIVE) { Vector3d eye = AVAWeaponUtil.getEyePositionFor(player); BlockRayTraceResult result = player.world.rayTraceBlocks(new RayTraceContext(eye, eye.add(player.getLookVec().scale(100.0F)), RayTraceContext.BlockMode.VISUAL, RayTraceContext.FluidMode.NONE, player)); if (result.getType() != RayTraceResult.Type.MISS) { ACTIVE = true; minecraft.mouseHelper.ungrabMouse(); if (minecraft.gameSettings.keyBindPickBlock.getKey().getKeyCode() == GLFW.GLFW_MOUSE_BUTTON_MIDDLE) AVAClientUtil.unpressKeybind(minecraft.gameSettings.keyBindPickBlock); VEC = result.getHitVec(); } } } else { int type = getHoveringType(minecraft); if (ACTIVE && VEC != null && type != -1) AVAPackets.INSTANCE.sendToServer(new PingMessage(VEC, ActivePingEffect.Type.values()[type])); reset(minecraft); } } else reset(minecraft); } If player's focusing, the middle mouse is down, then we check if there's terrain (block) in player's sight within 100 blocks, if not, reset the vec, regrab the mouse and set active to false. MouseHelper#ungrabMouse call allows players to move mouse around the screen.   Once we have the VEC set (where the ping will occur), we can render a line between the center of the screen and the ping location. (White line) { ActiveRenderInfo info = minecraft.gameRenderer.getActiveRenderInfo(); Vector3f view = info.getViewVector(); Vector3d vec = info.getProjectedView().add(view.getX(), view.getY(), view.getZ()); drawLine(stack, (float) vec.x, (float) vec.y, (float) vec.z, (float) pingVec.x, (float) pingVec.y, (float) pingVec.z, 255, 255, 255, 1.0F) } public static void drawLine(MatrixStack stack, float x1, float y1, float z1, float x2, float y2, float z2, int r, int g, int b, float a) { AVAClientUtil.drawTransparent(true); IRenderTypeBuffer.Impl impl = IRenderTypeBuffer.getImpl(Tessellator.getInstance().getBuffer()); IVertexBuilder builder = impl.getBuffer(RenderType.LINES); Vector3d view = Minecraft.getInstance().gameRenderer.getActiveRenderInfo().getProjectedView(); stack.push(); stack.translate(-view.x, -view.y, -view.z); Matrix4f matrix = stack.getLast().getMatrix(); builder.pos(matrix, x1, y1, z1).color(r, g, b, (int) (a * 255.0F)).endVertex(); builder.pos(matrix, x2, y2, z2).color(r, g, b, (int) (a * 255.0F)).endVertex(); stack.pop(); impl.finish(); AVAClientUtil.drawTransparent(false); RenderSystem.color4f(1.0F, 1.0F, 1.0F, 1.0F); } If you did not add the look offset to the camera position it will not be visible.   Then we send a packet to the server to notify all other players that I've ping the location. Once players receives the location of the pings, it's time to render them. RenderSystem.disableDepthTest(); AVAClientUtil.drawTransparent(true); Vector3d view = Minecraft.getInstance().gameRenderer.getActiveRenderInfo().getProjectedView(); Vector3d vec = activePing.getVec(); double distance = activePing.getVec().distanceTo(view); if (distance > 100.0F) continue; renderObjectAt(minecraft, activePing, world, stack, (float) (distance / 20.0F), 0.0F, activePing.getTexture()); double x = vec.x - view.getX(); double y = vec.y - view.getY(); double z = vec.z - view.getZ(); stack.push(); stack.translate(x, y, z); stack.rotate(minecraft.getRenderManager().getCameraOrientation()); stack.rotate(Vector3f.ZP.rotationDegrees(180.0F)); float size = (float) (distance / 200.0F); stack.scale(size, size, size); IRenderTypeBuffer.Impl impl = IRenderTypeBuffer.getImpl(Tessellator.getInstance().getBuffer()); String text = AVACommonUtil.round(distance, 2) + "m"; minecraft.fontRenderer.func_243247_a(new StringTextComponent(text), -minecraft.fontRenderer.getStringWidth(text) / 2.0F, 10, AVAConstants.AVA_HUD_TEXT_WHITE, false, stack.getLast().getMatrix(), impl, true, 0, 15728880); impl.finish(); stack.pop(); private static void renderObjectAt(Minecraft minecraft, EnvironmentObjectEffect object, World world, MatrixStack stack, float size, float offsetScale, ResourceLocation texture) { Vector3d vec = object.getVec(); stack.push(); Vector3d view = Minecraft.getInstance().gameRenderer.getActiveRenderInfo().getProjectedView(); double x = vec.x - view.getX(); double y = vec.y - view.getY(); double z = vec.z - view.getZ(); if (Math.sqrt(Math.pow(x, 2) + Math.pow(y, 2) + Math.pow(z, 2)) > 100.0F) return; stack.translate(x, y, z); Direction direction = object.getDirection(); if (direction != null) { Vector3i offset = direction.getDirectionVec(); stack.translate(offset.getX() * offsetScale, offset.getY() * offsetScale, offset.getZ() * offsetScale); rotateByDirection(stack, direction); } else { stack.rotate(minecraft.getRenderManager().getCameraOrientation()); stack.rotate(Vector3f.ZP.rotationDegrees(180.0F)); } if (object.doBlend()) { Color colour = new Color(world.getBlockState(object.getPos()).getMaterialColor(world, object.getPos()).colorValue); RenderSystem.color4f(colour.getRed() / 255.0F, colour.getGreen() / 255.0F, colour.getBlue() / 255.0F, object.getTransparency()); } AVAClientUtil.blit(stack, texture, -size, -size, size, size); RenderSystem.color4f(1.0F, 1.0F, 1.0f, 1.0F); stack.pop(); }   In the code I change the size of the object according to the distance ( (distance / 20.0F) ), so the object will stay at similar size no matter the distance between them, and so does the text size. The direction is always null, and doBlend is false. They are used in my other renderings.
