Hi all,
I'm having a problem with collision. Mi class generate a rectangle using the trimesh but when an object collide with the rectangle the car goes crazy. I don`t know what it happen. Somebody could help me?? here is the code than I'm using:
package util;
import java.nio.FloatBuffer;
import com.jme.math.Vector3f;
import com.jme.scene.TriMesh;
import com.jme.scene.batch.TriangleBatch;
import com.jme.util.geom.BufferUtils;
/**
* <code>Quad</code> defines a four sided, two dimensional shape. The local
* height of the <code>Quad</code> defines it's size about the y-axis, while
* the width defines the x-axis. The z-axis will always be 0.
