Projectile doesnt spawn

projectile doensnt spawn, please help

Probably you have incorrect position of cannon (and with that, of projectile spawn position). I had simmilar situation: cannon was too low and when projectile was spawning it was immediately destroyed by collision with floor. So check if your projectile is not colliding with anything other than cannon at spawn point.

The SpawnActor node is likely working, but the projectile is immediately colliding with the Cannon and is getting destroyed. This can be fixed in two ways:

  1. Adjust where the projectile spawns so it’s no longer colliding the Cannon
  2. Change the collision handling setting in the SpawnActor node to “Always Spawn, Ignore Collisions”

Option #1 is usually the best way to handle this problem, but sometimes option #2 is acceptable.
