Is there some sort of gdk command that would let you specify a certian x, y, z point along with a radius and it would check that radius from the point to see which models are in it?

like find models in radius of 256 from point 52,45,96?

EDIT: if not I could figure out how to do it on my own with a for loop, but if gdk had a command it would make things a lot easier.

Do you want to know if a model is actually in the radius, or if any part of the model is within the radius?

If it's the former, then you can just loop through each object and compare its distance to the point with the radius. If it's the latter, then you can create a sphere with the specified radius and position it at the specified point, then call Object Collision() with the sphere and each object you're checking, and if it returns a 1 then part of the object is in the radius.

You don't need to create an object to check for sphere collision (which is what you are doing really).

Instead, calculate the distance between each sphere, subtract both of their radii, and if the result is less than zero, they are overlapping.

You can get the object's radius by using the dbGetObjectSize function IIRC.
