impact resolution - the entities are merging -

I am experimenting using the code provided in tutorials.

I want to detect collision. I have used EVENT_IMPACT to detect the impact. However, I can see my two entities ( 2 planes - mig.mdl - from tutorial nr.10) are "merging" ( get one in the other) a lot until it is detected the impact. How to increase the resolution of detection? - if is possible? Bellow you can see the code.

I want the impact to be detected when the two entities are in contact.

Maybe is something wrong in my code? ( in this example I also can navigate with the joyistic and move the two entities)

You probably have to change the collision hull of the entities. You can do this by calling 'c_setminxmax(entity_name)' after you've created the entities...


Also 'POLYGON' should only be used on 1 of the colliding entities. It's not really meant for moving entities either.

DJB MASTER Thanks a lot!!! It works!!!!

Have a good day!
