Clone(true) bugs?

by Alex Rice · in Torque Game Builder · 10/05/2006 (10:06 pm) · 3 replies

Is anyone having erratic results with the t2dSceneObject::clone(true) member? I haven't got a recipe to duplicate this problem. It is probably a bug in my code. But I suspect clone(true) is returning corrupted sprites sometimes.

I have a FSM that I am iterating with onTimer() callbacks. One of my states calls clone(true) to spawn baddies. It works fine, they cloned sprites appear for a few times but after a while they on't appear on screen.

According to dump() info, I think they should be appearing on screen, but they are not. Here is a example mystery sprite that was created by clone(true). Wouldn't you expect it to appear on screen based on the following info? I ran setPosition("0 0") and setLayer("0") but still don't see this sprite. I even tried removing and adding back into the scenegraph. Any suggestions

I use clone to produce an array of 256 objects. In about 1 out of 40 runs, it will fail to produce an object (and just get 0). For now, I simply try again if it gets "0" after cloning. I haven't been able to reproduce it at will or seen any patterns. ...Yet.

Perhaps something similar is going on, though you seem to have an ObjectID.

Thanks for confirming Tom. I changed my code to instead of clone(true) do new t2dAnimatedSprite() and my game is running fine now. I suspect a tricky bug in clone() somewhere.

I also have seen some issues with clone(), but also have not been able to track them down. I'm pretty sure it's on the bug list (will confirm tomorrow), but without a reproduction case it's very difficult to track down.
