panda3D AI : movement...

Hi,

Always on panda3D AI. it seems when a NPC got a behavior like pursue, panda3D AI will orients the NPC directly on the target, but without a smooth move.
For example, you are pursuing a NPC, but you are behind it, and it has not seen you. You fire on it, and it does’nt rotate to you, but it is here directly front of you.
Is that possible to avoid this? how?
