[1.8] Entity textures for primed TNT

[thealbinosmurf]

I am new to Minecraft moding but not to coding or java. I just sat down and created a custom tnt mod and I copied the `EntityTNTPrimed.java`to do a custom explosion but when the block is activated and my `EntityNuclearTntPrimed` gets created it is invisible. Any help would be appreciated.

You should set up your own entity model.

1. Post your entity registration code.

2. Did you created/registered your TNT model?

How do you register non `TitleEntity` `Entities`?

[thealbinosmurf]

I tried adding:

int entityID = EntityRegistry.findGlobalUniqueEntityId();
EntityRegistry.registerGlobalEntityID(EntityNuclearTntPrimed.class, "nuclearTntPrimed", entityID);

 

but it did not help

[Abastro]

1. First, you should register your Entity using EntityRegistry#registerModEntity.

      (You have to specify the id. If you have only one entity, just putting 0 in it would be fine.)

2. TileEntities and Entities are totally different, just to note.

[Elix_x]

To change texture of tnt, you need to overhandle renderer of this entity. In client proxy in init section, register custom entity renderer. Than do what you what in it.

[Manslaughter777]

Show your tnt entity class. I had the same problem and had to change something in the entity class

 

EDIT:

The entity tnt class has 2 constructors, you need to write this.fuse = whatever number the other one is in the first constructor to.

[Manslaughter777]

Just write this.fuse = 80 in the first constructor and it should work

[Abastro]

It (the fuse field) is not related with this issue...

Anyway you should register custom entity renderer, as elix said.

It probably isn't... But that's what made mine work

[Abastro]

Anyway it seems that he didn't set up custom entity renderer.

Oh well if that's the case the fuse thing probably won't work either...

[thealbinosmurf]

Okay so a custom Entity Renderer like this? :

public class RenderEntityNuclearTntPrimed extends RenderEntity {

private static final ResourceLocation textureLocation = new ResourceLocation(UberTntMod.MODID + ":" + "textures/models/entityTest.png");

public RenderEntityNuclearTntPrimed(RenderManager manager) {
	super(manager);
}

@Override
protected ResourceLocation getEntityTexture(Entity par1Entity)
{
	return textureLocation;
}

}

 

 

 

And if so how do I get it to deal with the fact that my entity texture has custom top, bottom, side or should I join them into one file just for this entity I looked through the mc textures and saw no place where they did that though for normal tnt.

 

[Abastro]

Try using Techne. It would answer your questions and solve most of your problems.

[Elix_x]

Take look at RenderTNTPrimed.class. It is renderer class that renderers EntityTNTPrimed. It will answer most of your questions

How do you add the renderer to the entity?

[SkyGuard1]

Shouldn't your EntityNuclearTntPrimed extend EntityTntPrimed?
