Something simple I whipped up with the new stuff that was introduced into forge with the January update. Thought I'd share it here, nothing too amazing and I doubt I'm the first, but I hope this helps anyone that want's a good looking and working ladder.
Gravity Volumes don't work in custom games unfortunately. Good use of the volume though when they patch it up i may use that.
Thanks ^.^, I've been doing this since Halo 4, and I havn't seen any other maps making ladders this way so when they put gravity volumes in I knew I had to make one again and share it with the community, though I really doubt I'm the first to come up with this so don't credit me on it. also I see your point, however the way I saw it was that if this was on a competitive map, no one would really understand that they would be able to climb the ladder, since there's no prompt saying jump to climb ladder, so I figured at a gameplay standpoint, the floating purple stuff would catch some people's eye and at least hint that there's something unique to the ladder. That's kind of how I saw it. Both ways work just fine, unfortunately I've been told they don't work in custom games so if that's the case hopefully they patch that quickly. Really? dang that sucks, hopefully they patch it soon. I'm glad this little trick might come useful for you.
After going back and playing halo 1 I'm pretty sure I've moved on from ladders. Props on your solution though.
God! I'm so frustrated! They finally add gravity volumes, which I need for a minigame concept I've had since before launch.... .....aaaaaand they're broken.
