[1.9.4] Help with Reflections needed, it always catches an exception

Posted August 29, 20169 yr

Hey everyone,

I am currently in the process of updating a mod to 1.9.4 and I try to get rid of the Access Transformer, so I tried to get the variable with a Reflection but everytime I do "getInt" to the field it just catches an exception.

int i;

public ClientTickHandler() {
	try {
		sprintToggleTimer = ReflectionHelper.findField(EntityPlayerSP.class,  "sprintToggleTimer", "field_71156_d");
		i = sprintToggleTimer.getInt(mc.thePlayer);

	}

	catch (Exception e) {
		SimplyJetpacks.logger.error("Unable to find field \"sprintToggleTimer\"");
	}
	System.out.println("i = " + i);
}

Hope someone can help me

The one I had defined: "Unable to find field sprintToggleTimer"

That's not the actual exception. You have this:

catch (Exception e) {

This is known as a Pokemon Catch Block. I.e. "gotta catch em all!"

You didn't even then print out the error but instead a generic "I had a problem" message.

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.

Where are you creating an instance of ClientTickHandler? I'm assuming you do it in one of the initialization states (pre-init probably), which means mc.thePlayer will be null. You can fetch the field from EntityPlayerSP in your constructor, but you cannot read it while not in-game.

So the error is just with my "debug" integer i... I see...

The weird thing is that the exception is not caught ingame but it is not working like I supposed it to be either.

if(!sprintKeyCheck && sprintToggleTimer != null && mc.thePlayer.movementInput.moveForward >= 1.0F && !mc.thePlayer.isCollidedHorizontally && (mc.thePlayer.getFoodStats().getFoodLevel() > 6.0F || mc.thePlayer.capabilities.allowFlying))
	{
		if (sprintToggleTimer.getInt(mc.thePlayer) <= 0 && !mc.gameSettings.keyBindSprint.isKeyDown()) {
			sprintToggleTimer.setInt(mc.thePlayer, 7);
                sprintKeyCheck = true;
            }

		mc.thePlayer.setSprinting(true);
	}

This (coupled with some other methodes) should make it possible to sprint in midair with the jetpack to activate its boost, but as a result I am always sprinting as soon as I am not on the ground which is not what should happen

Okay I figured it out was just a really dumb mistake... I just forgot the "else" after the "if" :-X

But thanks everyone for the help

How to add my mob to another mod's biome in 1.20.1.

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)
