Hello,

Well, I'm stumped. I've tried searching the wiki and other sites for the various terms I thought would apply, but nothing.

In the map I have, the player needs to put a cube on top of an arm, then press a button to raise the arm up on a timer to bring it into line with a laser receiver. I have the arm etc working ok, but when you press the button to raise the arm the lasercube is always flung off. I've tried setting the animation speed to 10%, but still no joy. Is there something I can do to not have the cube catapulted away?

Thanks in advance for any help!

So the cube is resting on the arm while the arms being raised? Maybe stick a box-shaped button prop (the square button that holds a cube) to hold the cube?

Yes, currently there's a glass-topped arm that raises straight into the air. I'd like the cube to sit on this and be lifted into the air.

I'd rather not add the cube-button, as the button wouldn't do anything itself, would be slightly confusing and I feel there should be a way to do this.

How about a small "NoDraw" wall brush to keep the cube from falling? Not too big but just enough to keep the box from falling. Say about 4 units high?

The problem seems to be that when the arm activates, the cube bounces a bit on top of it. Sometimes just a small amount, sometimes quite a bit. Also, the player needs to be able to walk on the area to place the cube at first.

It's very frustrating!

Simple fix: func_brush box around the panel's top parented to the top that holds the box in. starts disabled. When the panel is triggered to go up, turn it on. When it's finished moving, turn it off. Same for when it's dropping, turn it on then turn it off. So basiclly what MasterLagger said only mobile and turned on/off.
