Why Won't Projectiles Collide with Map?

Hi -

I’ve set up a couple of projectiles now, based on both the Twin-Stick-Shooter tutorial from Epic, as well as the “bombs” created in Epic’s Blueprint Networking Tutorials.

In neither case am I able to get the projectile to collide with the geometry in the Twin-Stick_Shooter example map. The level geometry has collision components on the static mesh actors that make it up, and I’ve tried setting the collision on the projectiles to “BlockAll” as well as setting up special projectile collisions. No matter what I do, the projectile flies through the world collision.

Any idea why my projectiles aren’t colliding?

Thanks!

I figured it out - I had to replace the DefaultSceneRoot of the projectile by dragging one of the projectile components on top of it.

I’m not sure why leaving the DefaultSceneRoot was blocking the functionality, but as soon as it was replaced, everything started working as expected.

I went back and watched the Blueprint Networking Tutorial, and when the bomb was created by adding a sphere component, it automatically replaced the DSR. For some reason that does not happen when I’m adding components, but now I know to watch out for this!

Thanks MonsterDrew, over a multitude of post that ask this same thing, this is the only one that answer with the solution. Seems like everyone is giving for obvious that when you creater an actor there is an useless root component to be substituted…
