I have tested my game again. Then I noticed something strange. I recorded a demonstration video.
Function “Deactivate” does not works on Pooled Projectile component.
When I use function “Deactivate” to normal projectile movement component, they stop moving.
But when I use function “Deactivate” to Pooled Projectile component, they still moving.
I use function “Set Direction” to x=0 y=0 z=0 too, But they do not stop moving.
I also cannot use function “Set velocity” in Pooled Projectile as I use in Projectile Movement component.
