so im wondering what other people are using to detect an edge that you do not want your bad guys falling off but you do want the hero to fall off and maybe die or lose some health.

i have thought about this and i dont know what the best choice is.

the easiest way would be to build a wall object,hide it and only enable collision detection for it with bad guys.... or i need to check ground height clearances around the character and try to guide him away.

what would you guys do for this scenario...see image below.

You can use Sprite Hit Groups. Allow the enemy group to hit, but not your player. You do this by setting pairs of groups that can collide with one another.

The 3D physics has collision groups. Use SetObject3DPhysicsGroup(). Just remember if you use collision groups you must use them for
all objects in your world.

P.S. Just noticed Paul left out part of the help for the command.
Here is the parameters.

Another way to do this is to have a hidden plain that sits just in front of the player and extends into the ground to the depth that you consider to be the maximum depth that the player can step down.
Then check collision detection between the plain and the ground. If there is a collision, the player can continue to walk in that direction. If not then he is at the edge of a cliff.

Humm... I like that idea scraggle. If i put 2 of these infront of the characters moving direction i could probably also detect if the character could jump a hole to another platform.

Or use the same one and just move it ahead to see how far the hole goes to a jumpable distance.

Thanks

I use something like this:
this method allows you even stair step detection.
