ph_num_contacts
The total number of physics contacts of the last frame can be found in
this variable. A contact is generated for every vertex of a physics shape intersecting
another model or level block. PH_SPHEREs creates one contact point per
collision, PH_BOXes up to 4, and PH_POLY an unlimited number of
points. You should monitor this variable to see if an excessive number of contacts
are being generated and consider calling phent_settype() with a simpler
collision shape. The value of this variable is also useful for debugging vehicles
to make sure that all wheels/tracks are touching the ground.
Range:
0 .. unlimited
Type:
var, read only
Example:
if (ph_num_contacts < 4) { print("ground contact lost!"); }
