DESCRIPTION:Hi all,\n\nI have objects in a scene which I surround with an i
nvisible box(which is used for collision detection).\nUsers enter an amount
to move from keyboard and objects move. The problem is I cannot get the ob
jects to recognise when another object is in contact with it? Any help woul
d be great.\nCheers.\nps. source code for collision class below\n\nimport j
