I created a (very) simple map that has the sole purpose of jumping on a button several times to open the end door. I have been trying to create a counter on the wall to display how many more times you need to jump on the button to open the end door, and haven't gotten anywhere. I am trying to do this so that I can create bigger maps that incorporate both aspects later. Here is my page for the map on steam: http://steamcommunity.com/sharedfiles/filedetails/?id=68484764
Thanks for any help you can give.

I gotta admit that the counter above was pretty cleverly designed, but I don't think that there is a way to make it count down unless you want to make something really messy.

PAINT SKILLZ HAXXOR!

Connect the buttons to the door and connect the jump-button to the lightbridges like you did in your previous map.

I don't know what application this thing would have, but there you go...

It's way easier in Hammer

This is pretty interesting, although I'm not sure what puzzle applications you could have for hitting the same button multiple times. Especially if you give the player a visual indicator as to how many times they have to hit the button.

As for what you can do to make a visible counter, I think Hammer is your best bet.

Hammer definitely. The PTI editor is majorly limited with complex logic.

Look up how to use a math_counter.
If you want to display a number gui somewhere, try searching TWP for anything that might help.
Consequently I found this: post31123.html however that might not be the best thing to use.

If you become stuck: I can edit my Underground Timer instance to suit your needs.
