So I downloaded Hammer a few days ago and I've been screwing around with it a bit. I think I've got the hang of the basics, but I just ran into some issues. I wanted to try making an activatable teleporter thing. I attached a prop_button to a trigger_teleport, which worked fine. However, when I tried to get it to only teleport cubes (prop_weighted_cube, to be precise), it stopped working. You can take a look at my map here. What painfully obvious mistake did I make?

For teleporting an object the destinations of the object should probably be an info_target and not a info_player_destination -> these are meant for the player and probably will not be too accurate for an object.

Secondly (most importantly), in the flags tab in your trigger (which you should really change to a trigger texture) tick the one that says Physics Objects.
