Raycast obstacle avoidence with sphere collider issue

[Mcg]

I’ve been looking around at ways to do obstacle avoidance and found using raycasts on sphere colliders to get the normal point and adjust the moving direction but I found a scenario that stops it working.

This is what generally happens

But this happens when the sphere colliers are aligned (this case was the same Y positions ) and the hit point normal returned just comes straight backwards.

Was wondering what the best approach would be to solve this?

Easiest solution would be to just add a random 0.00001f to each axis during avoidance calculation.

Alternatively, check if the normal is within a small tolerance of the reciprocal of the movement vector.

awesome thank you
