I think it would be handy to have a collision flag for entities.
something like..

g_Entity[e]['collision'] = 0
g_Entity[e]['collision'] = 1
g_PlayerCollision = 0
g_PlayerCollision = 1

Say if an entity collides with another entity, then both would report back 1.
I'm working on a pickup and carry script and it would be good to have feedback to know when two or more entities have collided so you can script to drop the object instead of the entity going through walls, etc.

The collision flag would work from the entities collision boxes around it. So if two or more collision boxes hit each other, then it reports.

It would also be good to use it as an event flag, say if a car hits a wall or another car, you could trigger a sound effect or animation, etc.
I think you would want it to report 1 for a collision even if the entities have their collision turned off.
Ill keep with the car theme, picture a finish line beam / ribbon across a track and when the car passes through the ribbon (which would have its collision turned off) it would report back 1 once the car passed through it, and so would the car.

There are lots of different ways you could use a flag like this.

It should even work with the player collision box, and maybe a collision flag for the player as well, like g_PlayerCollision.

But you wouldn't want it to report collision with the terrain.

you sure do know how to dream... but yes completely agree, collision feedback would be great

also the ability to return the size of an object (in all directions - x,y,z) would be nice (you could then detect if it's only a minor collision with a smaller object for example)

and also the ability to return the height of the terrain at any x,z point (not directly related but i think this is needed to detect when an object is "colliding" with the terrain)

And also the entity id (number) that collide with.

And some command to get the entity id, something like "GetEntityID", and so on....
