Is there a trigger that allows you to build a sentry in seconds?

Long story short, I'm making a jump map specifically for Engineer and I was wondering if there's some kind of trick in Hammer that allows you to insta-build sentries.

I believe a "trigger_add_or_remove_tf_player_attributes" brush is what you're looking for.

Set the attribute to "engineer sentry build rate multiplier", and experiment with the value number. I think '999' would give you what you're looking for, but that's just a guess since I haven't tried it myself.

You'll still need players to upgrade their sentries, but this'll make them construct in the blink of an eye.
