This is very simple.

Here is an example:

First, you must uncheck the “Auto Active” checkbox in the projectile movement component.

Then, in the NPC char you use “SuggestedProjectileVelocity” node, where given a speed, an origin and destination locations, it gives you the velocity vector required to reach the destination point. So:

In your NPC, just call that function after spawning the projectile.

305005-4.jpg

Now, adapt this to your case.

PS: If can’t reach target, then the velocity returned by SuggestedProjectileVelocity is (0,0,0).
