[1.9.4] Change Entity Model Size

Hi. I was wondering how (and if) I can resize a specific box in an entity's model. To put it in a perspective imagine a creeper that is about to explode. It expands. For example I want to make only the body to expand... (I do not want to apply this to a creeper) Let's take an example code...

public class ModelExample extends ModelBase {

ModelRenderer box1;
ModelRenderer box2;

public ModelExample() {
box1 = new ModelRenderer(this, 0, 0);
	box1.addBox(0F, 0F, 0F, 1, 1, 1);
	box2.setRotationPoint(0F, 0F, 0F);
	box1.setTextureSize(32, 32);
	box1.mirror = true;
	setRotation(box1, 0F, 0F, 0F);

box2 = new ModelRenderer(this, 18, 0);
	box2.addBox(1F, 0F, 0F, 1, 1, 1);
	box2.setRotationPoint(0F, 0F, 0F);
	box2.setTextureSize(32, 32);
	box2.mirror = true;
	setRotation(box2, 0F, 0F, 0F);
}

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);
	box1.render(f5);
                box2.render(f5);

}

private void setRotation(ModelRenderer model, float x, float y, float z) {
	model.rotateAngleX = x;
	model.rotateAngleY = y;
	model.rotateAngleZ = z;

}

public void setRotationAngles(float f, float f1, float f2, float f3, float f4, float f5, Entity entity) {
	super.setRotationAngles(f, f1, f2, f3, f4, f5, entity);
}

 

How can I edit the size/dimensions of box2?

Use GL11#scalef with some factor. E.g: 1.25F before calling box2#render and 0.8F after (to revert scaling).

You can also use GL11#push/pop-Matrix and/or GL11#translatef if you need to align scaled box to "fit" other boxes.

Its pretty straight forward unless you start doing complex models with connected/moving parts - then you have some more math.

 

Oh and btw: In method Model#render - last param is scale (In 1.10+) - that one should be used rather for whole model.

If you want part-specific scaling values you can save them in Entity (which is passed to Render#render and Model#render) or @Capability if you are replacing models/renders of not-your entities.

 

Big note: 1.10 has whole render/model system decoded, I highly recommend updating, makes things much clearer.

1.7.10 is no longer supported by forge, you are on your own.
