Get a Reference to the VoxelObject

Next we need to change the way the voxel button looks when you step on it. To do that, we need a reference to this entity’s voxelObject.

1. In the onCollisionEnter function, create a new variable called voxelObject.
2. Use this.entity.getComponentByType to find a particular component on this entity. 
3. Give ComponentType.VoxelObject as the input so that we are looking for a VoxelObject.
