Rendering multiple models

[RafaMv]

Hey guys, I would like to render a mob that will have different modelbases. Just imagine a robot that can change its arms. However, I don't know how to render the models separately (and properly). Does anyone have a good idea how to do that?

 

I tried this:

public void renderModel(Entitybot bot, double x, double y, double z, float u, float v) {

ModelBase modelPart;

ResourceLocation texturePart;

GL11.glPushMatrix();

GL11.glTranslatef((float) x, (float) y, (float) z);

GL11.glRotatef(180.0F, 0.0F, 0.0F, 1.0F);

for (int i = 1; i < 5; i++) {

modelPart = (ModelBase) bot.getModelPart(i);

if (modelPart != null) {

texturePart = bot.getTexturePart(i);

bindTexture(texturePart);

modelPart.render(bot, 1.0F, 1.0F, 1.0F, 1.0F, 1.0F, 0.1F);

}

}

GL11.glPopMatrix();

super.doRender(bot, x, y, z, u, v);

}

See that bit that says "modelPart.render"?  Yeah.  That's the bit responsible for rendering a given part.

Depending on how drastic the differences are, you could put the different parts in a single model class and render the appropriate part according to the entity's state (which you would need to sync to client with DataWatcher or other means).

 

What I mean is basically this:

public class YourModel extends ModelBase {
private ModelRenderer arm1;
private ModelRenderer arm2;
private ModelRenderer everythingElse;

@Override
public void render(Entity entity, float f, float f1, float f2, float f3, float f4, float f5) {
super.render(entity, f, f1, f2, f3, f4, f5);
setRotationAngles(f, f1, f2, f3, f4, f5, entity);
everythingElse.render(f5);

if (((YourEntity) entity).useArm1()) {
arm1.render(f5);
} else {
arm2.render(f5);
}
}

 

Obviously you could make the code look nicer by using an array for all the possible arms and returning the index of the arm to use from your entity's function, but this is the basic gist of it.
