[EDIT]

I just put this in the render class.

  @Override
    protected ResourceLocation getEntityTexture(EntityGolemObsidian entity) {
        if(entity.isLavaForm()) {

            if (entity.ticksExisted % 3 == 0) {
                this.textureIndex--;
            }

            if (textureIndex == -1) {
                textureIndex = 15;
            }

            return golemLavaTextures[textureIndex];
        }
        else {
            return golemObsidianTexture;
        }
    }

 

[OP]

Hello.

 

I have an entity where I would like lava to appear to be flowing down its body. I have tried to google every form of "forge animate entity texture" and have only seen threads where item and block textures are animated, or the model is animated. I have created a texture for each frame of the animation and my idea is to render one frame every or every other tick. I don't know how to tell Minecraft to render a new texture every tick. How do I do so? Or is there another more efficient manner of doing so?

 

The render class https://github.com/EstebanZapata/ObsidianTools/blob/mob/src/main/java/com/estebanzapata/obsidiantools/client/renderer/entity/RenderGolemObsidian.java

public class RenderGolemObsidian extends RenderLiving<EntityGolemObsidian> {

   // private static final ResourceLocation[] golemLavaTextures =  new ResourceLocation[16];
    private static final ResourceLocation golemObsidianTexture = new ResourceLocation(Reference.RESOURCE_PREFIX + "textures/entity/golemObsidian.png");
   // private static final ResourceLocation golemLavaTexture = new ResourceLocation(Reference.RESOURCE_PREFIX + "textures/entity/golemLava.png")

    public RenderGolemObsidian(RenderManager rendermanagerIn, ModelBase modelIn, float shadowSizeIn) {
        super(rendermanagerIn, modelIn, shadowSizeIn);
        //this.initLavaTextures();
    }

    /*protected void initLavaTextures() {
        for(int i = 0; i < golemLavaTextures.length; i++) {
            golemLavaTextures[i] = new ResourceLocation(Reference.RESOURCE_PREFIX + "textures/entity/golemLava" + i + ".png");
        }
    }*/


    @Override
    protected ResourceLocation getEntityTexture(EntityGolemObsidian entity) {
        return golemObsidianTexture;
    }


    protected void rotateCorpse(EntityGolemObsidian bat, float p_77043_2_, float p_77043_3_, float partialTicks)
    {
        super.rotateCorpse(bat, p_77043_2_, p_77043_3_, partialTicks);

        if ((double)bat.limbSwingAmount >= 0.01D)
        {
            float f = 13.0F;
            float f1 = bat.limbSwing - bat.limbSwingAmount * (1.0F - partialTicks) + 6.0F;
            float f2 = (Math.abs(f1 % f - f * 0.5F) - f * 0.25F) / (f * 0.25F);
            GlStateManager.rotate(6.5F * f2, 0.0F, 0.0F, 1.0F);
        }
    }
}

 

Client proxy https://github.com/EstebanZapata/ObsidianTools/blob/mob/src/main/java/com/estebanzapata/obsidiantools/proxy/ClientProxy.java

public class ClientProxy extends CommonProxy {
    public void preInit(FMLPreInitializationEvent event) {
        super.preInit(event);

        RenderingRegistry.registerEntityRenderingHandler(EntityGolemObsidian.class, new IRenderFactory<EntityGolemObsidian>() {
            @Override
            public Render<? super EntityGolemObsidian> createRenderFor(RenderManager manager) {
                return new RenderGolemObsidian(manager, new ModelGolemObsidian(), 0.5f);
            }
        });
    }

    public void init(FMLInitializationEvent event) {
        super.init(event);
        ItemsRender.init();
        BlocksRender.init();
    }

    public void postInit(FMLPostInitializationEvent event) {
        super.postInit(event);
    }
}

Couldn't you look at RenderCreeper to see how it renders the charged effect?
