You means modding ? If yes just follow https://mcforge.readthedocs.io/en/1.15.x/ If you means mcp, unzip the version that you want (http://www.modcoderpack.com/website/releases) then follow a tutorial If you think it's eclipse, check if you're using JDK8 (not 13)

Actually it didn't quite work in the nether, but now it does. The reason I am posting this is, that if someone has the same problem in the future, they will find this. I searched for this on google for a good hour, but didn't find anything. New code: @SubscribeEvent public void render(RenderWorldLastEvent event) { IRenderTypeBuffer.Impl buffer = Minecraft.getInstance().getRenderTypeBuffers().getBufferSource(); IVertexBuilder builder = buffer.getBuffer(RenderType.LINES); MatrixStack matrixStack = event.getMatrixStack(); PlayerEntity player = Minecraft.getInstance().player; double x = player.lastTickPosX + (player.getPosX() - player.lastTickPosX) * event.getPartialTicks(); double y = player.lastTickPosY + (player.getPosY() - player.lastTickPosY) * event.getPartialTicks(); double z = player.lastTickPosZ + (player.getPosZ() - player.lastTickPosZ) * event.getPartialTicks(); matrixStack.push(); matrixStack.translate(-x, -y, -z); Matrix4f matrix = matrixStack.getLast().getMatrix(); builder.pos(matrix, 0, 0, 0).color(1f, 0, 0, 1f).endVertex(); builder.pos(matrix, 0, 256, 0).color(1f, 0, 0, 1f).endVertex(); matrixStack.pop(); RenderSystem.disableDepthTest(); buffer.finish(RenderType.LINES); }

Yeah so my idea does include to limit the possible configs. Since you can't register blocks from a config file, you have to register a specific amount. This also means you must have an addon per mod that add ores. It will indeed limit a lot the possible configs for a direct user. However, you could try and integrate an api for modpack creators that could then more precisely define and configure the details of your ores. I have been managing a mod with a lot of config options for the last 2 & 1/2 months and I feel that having easy configs is much better than having tons of config for direct users. In that mindset, limiting the possibilities of your config could improve user experience: having a config that is just changing 5 numbers and boom gold is super dense, coal less, iron and diamond medium and then they can play. (Reread what you said and not sure I understand what you mean by the density variant isn't the only thing you wanted? Also for the density levels, my bad thought that you were drawing multiple blocks per ore blocks...) Of course this is your mod not mine so if you really want mass configurability it doesn't seem to be possible purely using forge's config system. They also will not add any support for something like this since the "policy" is to always register everything, meaning it shouldn't depend on configs.

Howdy My usual strategy for solving this sort of problem is 1) For a method in a small class, I just open the new class and browse it looking for code which is similar to the 1.14.4 code If the class is large or the method has moved out to another class 1) Use my IDE to search for all usages of the method in 1.14.4, and make note of a distinctive class/method which uses it 2) Go to the same class+method in 1.15.2 and see what the same code is calling now. YOu might also find these links helpful https://gist.github.com/williewillus/353c872bcf1a6ace9921189f6100d09a and https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e Cheers TGG

Ok, here's repo. I set it public now. https://github.com/immortalmice/FoodPower This mod is under construction, so everything will be what I mention in README.txt. My mod have many parts. About making food, this mod has some cooking patterns, such as cake, pizza, salad...etc. You can select a pattern to make a recipe, pattern will tell you what ingredients is necessary, and what is optional(with certain food types). With recipe, you can follow cooking steps on it to make your food by using oven, frying pan, juicer...etc. Depend on what you used in this food, after eating it will give you some buff and some special experience. Experience will help you on cooking new meals, and most important - some special power for you in gaming minecraft. And there some other features in this mod, so I still working hard for it

Hi If you can't modify the server, and there is only one or a few chests that you're trying to track, then you could consider the client tick event; once every (eg) 20 ticks you could check to see if the chest still exists at the expected location. Likewise you could periodically check the chest contents to see if they have changed. That would detect changes not caused by the local player. I can't think of any other client events which are triggered on updates to changes to chest contents. -TGG

Thanks for your reply! Finally got it working correctly! new code: public class PathRenderer { private Minecraft mc; public PathRenderer() { mc = Minecraft.getInstance(); } @SubscribeEvent public void render(RenderWorldLastEvent event){ Tessellator tessellator = Tessellator.getInstance(); BufferBuilder buffer = tessellator.getBuffer(); MatrixStack matrixStack = event.getMatrixStack(); Vec3d pos = mc.player.getPositionVec(); matrixStack.push(); matrixStack.translate(-pos.x, -pos.y, -pos.z); RenderSystem.color3f(1, 0, 0); RenderSystem.lineWidth(6); buffer.begin(GL11.GL_LINES, DefaultVertexFormats.POSITION); Matrix4f matrix = matrixStack.getLast().getMatrix(); Color c = new Color(1f, 0f, 0f, 1f); drawLine(matrix, buffer, new Vec3d(0, 57, 0), new Vec3d(5, 57, 0)); tessellator.draw(); matrixStack.pop(); } private void drawLine(Matrix4f matrix, BufferBuilder buffer, Vec3d p1, Vec3d p2) { buffer.pos(matrix, (float)p1.x + 0.5f, (float)p1.y + 0.5f, (float)p1.z + 0.5f).endVertex(); buffer.pos(matrix, (float)p2.x + 0.5f, (float)p2.y + 0.5f, (float)p2.z + 0.5f).endVertex(); } }

Hi yes a lot has changed. In particular, the code no longer uses the OpenGL transformation matrices, it keeps track of its own in a MatrixStack. So you need to supply the MatrixStack to the rendering method.

I just want to add new blockstate and model WITHOUT creating new file in assets. Only in code, maybe from String
