 Re: User Triggered Map Displacement?

Hi guys,

I was just wondering if it's possible to say, when a user does a certain thing (for example, presses a button), they ground at a certain spot would displace a certain way. Basically I want an explosion that will displace the ground to resemble a small metor crash, or something along those lines.

So is it possible, and how?

Thanks in advance!

No, displacements can't move. You're going to have to fake it: model the craters by hand using displacements or map geometry, cover the craters with a surface func_brush, and then toggle the func_brush when the meteor hits. The concept is kind of similar to a punji pit, except without the sharp jabby skewers at the bottom. image

Alternatively, you can try hacking something together with the env_terrainmorph entity, though there's some bugs associated with it and I haven't used it personally - I'm not even sure how well it works, but you can give it a shot I guess.

I think using CJ's idea you could also:

1) Have the cover layer with a high breaking tolerance (so weapons cannot shoot the spot) and have it a func_breakable. Set some sort of a blast to detonate it.

2) have a func_door on the parts to move fast downward. That way during the blast flash, you'll overlook them sinking.

/me shuts up now with stupid suggestions.





The best things in life, aren't things.

Just out of curiusity, when the func_brush is triggered the displacement would show instantly right? As opposed to animated.

Yes, but if there's an explosion effect from the meteor, people aren't going to notice.

Indeed, thank you very much. I might just make it so that the player is to far away to notice, but when they go back to the area it will have changed.

Thank you!!!<html><head><link rel="stylesheet" href="themes/standard.css" type="text/css"></head><body topmargin=2 leftmargin=2>

Mark my suggestion as correct and I'll get 5 big ones. :P

Even though I haven't tried it, I know it'll work.

Five big ones for you <img src=" SRC="images/smiles/icon_biggrin.gif">
