Projectiles are flopping out of the barrel (simulate physics)

[vagnerlands]

After the exercise of lesson 233. Projectile Movement Component, I got a projectile being fired as expected. I realized that the projectiles weren’t hitting the targets, so I’ve:

1. added a (simple) collision sphere to the static mesh of my projectile;
2. in the projectile BP, I’ve set Simulate Physics.
   For some weird reason, now the projectile just flop out of the barrel and roll to the ground.

I’m using UE4 4.24.3 and I am suspecting that it has something to do with Projectile Movement component.

Anyone else had this problem?

Don’t simulate physics on the projectile.

[vagnerlands]

Indeed DanM, I’ll use only collision and overlaps events in the future for damage and animation effects.

@vagnerlands

flop out

Same to me

In projectile.cpp BeginPlay function, add ProjectileMovementComponent->bShouldBounce = true; (not in constructor)

It is better these properties show up on the BP_Projectile blueprint editor like below, but native C++ derived Projectile Movement component doesn’t shows (I don’t know why).

It seems it is better to use standard(added by “Add component” button) projectile component (we shouldn’t create projectile by “C++”) when we create actual game as a product…
