[SOLVED] [1.6.4] Hit Box Not Right Size

Recommended Posts

so as part of my mod i'm adding a chicken that is 3 times the size of a normal chicken, but the problem is that the hit box is remaining the normal size, and im not sure how to go about changing the size of it.

 

Here is my code:

 

 

ModelGiantChicken:

package mods.mochickens.mobs.models;

import org.lwjgl.opengl.GL11;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.model.ModelRenderer;
import net.minecraft.entity.Entity;
import net.minecraft.util.MathHelper;

public class ModelGiantChicken extends ModelBase
{
  //fields
    ModelRenderer lleg;
    ModelRenderer rleg;
    ModelRenderer body;
    ModelRenderer lwing;
    ModelRenderer rwing;
    ModelRenderer head;
    ModelRenderer bill;
    ModelRenderer chin;
  
  public ModelGiantChicken()

a lot of the code in the entity class is place holder for now. could someone please show me where it sets the size of the hitbox?

Hi

 

The hit detection for where the user's mouse is pointing is done in

EntityRenderer.getMouseOver

 

                for (int i = 0; i < list.size(); ++i)
                {
                    Entity entity = (Entity)list.get(i);

                    if (entity.canBeCollidedWith())
                    {
                        float f2 = entity.getCollisionBorderSize();
                        AxisAlignedBB axisalignedbb = entity.boundingBox.expand((double)f2, (double)f2, (double)f2);
                        MovingObjectPosition movingobjectposition = axisalignedbb.calculateIntercept(vec3, vec32);

 

So if the hitbox is the same for the other code (which I guess it probably is), then it looks like changing entity.boundingBox should do what you want, this is done in the vanilla code by setting Entity.width and Entity.height which is done in Entity.setSize().

 

So in EntityGiantChicken your

this.setSize(0.3F, 0.7F);

should be bigger.

 

Never tried it myself, but looks promising.

 

-TGG
