I was trying to make a small mod in TF2. However, the only main problem I have is the implementation. Is there anyway to detect if an object enters a certain region in the map? (Ex. Sandman ball, rocket, etc)

Thanks.

The only approach is sort of nasty. On a timer, every 0.3 seconds or so, loop through all the entities (FindEntityByClassname), determine if its a sandman ball or projectile, and then compare its location to your predetermined region.

If you need anymore help getting started, just ask.

Like what my idea is, is that when the sandman ball (or object) goes into "hole" then the person gets a point.
It's like those sack toss games that you play when you were little.

Neat, if you were making your own map for this there might be a smarter, yet more complicated way.

You could use the SDKHooks extension and hook the projectile entity's Touch function to tell when it collides with another entity. This means that you'll have to mark the region with another entity and test for it. Can't say off hand which entity would work. trigger_hurt maybe? You just have to play around and see.

The only problem is:
Can the collision be restricted to the Sandman ball?

[pheadxdll]

Yeah, just make the region solid, or put it above a solid object.

1. How would I make the region? Would I have to apply a special texture on a rectangle block?
2. What do you mean by "solid"?
3. Can anyone give me an example touch trigger?

What about using env_beam and hooking OnTouchedByEntity output? Use just enough to cover your "hole" and if they are touched by sandman balls ~~~> SCORE!
