How would I detect how many objects are being collided with?

[SubWooferX3]

I'm currently working on a level generator, and I need to detect how many blocks an object is colliding with. So for example, if it's colliding with 2 objects on one loop I need to set a counter to "2" and if it's overlapping 4 on the next loop I need to set the counter to "4"

I just did an example mfa for someone else that, among other things, did this. See my bottom post here:

By the way, you seem to be using the words "colliding" and "overlapping" interchangeably. My method used overlapping. I assume you mean overlapping (returns true as long as objects are touching) rather than colliding (returns true only upon first contact between two objects)
