Ty for the info.

Also I noticed that adding a "EVENT_FRICTION" in the event of e.g. the player and setting "pXent_setcollisionflag(player, my, NX_NOTIFY_ON_START_TOUCH);" in the action of the rigid bodies also works for a collision event.

I haven't checked yet if it is possible to set "pXent_setcollisionflag" multiple times to link each rigid body with each character, but that would be pretty sweet if that is possible (for enemies etc.).
