Hey,

I'm currently working on my A.I. of the game, now I have A.I. on platforms and they need to move freely on the platform but they need to know when to stop moving when they approach an edge so they don't fall off.

I've been trying to do this with rays but it hasn't been very successful. My question is: Are there better solutions?

Thanks!

Have you tried casting the ray down and to the front of the AI so you get a prediction of an edge?
What about getting the position and size of the platform and making sure the AI does not exceed those bounds?

NavMesh ?

...or check distance from the edge? ...but when platform have irregular shape then it may be problematic, so NavMesh imo is best choice.

Ah, i solved it. Turns out that the ray was hitting the AI. All i need to do was setting: actor.ray(false); -raycast- actor.ray(true);

Thanks for the replies and help!
