Could anyone tell me how to make energy ball launchers and catchers do something useful? I have them up and running, but I don't know how to make them open a door, or in this case, kill a brush entity (one that is being used as a wall). Any help will be greatly appreciated.

PS: I am using a prefab catcher an launcher with "OnTrigger" and "OnSpawn"
outputs

On the orb catcher there should be a trigger_multiple, this what "catches" the ball and activates everything. You should see the outputs in there already. Just add a OnTrigger>Door>Open type output and you're golden.

Read here for more info on orb catchers.

The thing is, the OnTrigger output is counted as invalid (red) so it does'nt work

click the drop-down menu and choose whatever seems most likely to act in a similar way to OnTrigger

OnStartTouch perhaps?

Thank you all for the help. I got it working. The door won't animate right (pushing backwards and then resetting itself instead of moving to the side),so I replaced it with a wall that is 'killed' OnTrigger.

Just change the doors "move direction" property to get it to move the right way. Also change the reset property to -1 if you want the door to stay open (at least till you want to shut it). Don't forget to uncheck "touch opens" in the flags tab.
