How to a creative_prop in the way the player its facing?

Hi!

This is a pretty basic question, but I don´t realize to do it. My idea is to spawn a projectile in the player´s position and move it forward.

I tried to take the camera´s and the spawned projectile´s location and substract them to create the direction vector.

After that, I take the player´s location and substract the direction vector so now in theory I have the new position forward the player in direction of the camera. Here is my idea in 2D:

It works, but if I make the game in first person the code is completly useless

I think this is super complicated and I thought that maybe there is a better way to do it or a function that can do it. Any idea?

I just found that there is a very usefull function called “GetLocalForward()” with this I can make the same process as before, but now the code works also in first person.

Here is it.

ForwardVector:=Rotation.GetLocalForward()

      
      #CAMERA 
      Camera_LocationX:=Character.GetViewLocation().X
      Camera_LocationY:=Character.GetViewLocation().Y
      Camera_LocationZ:=Character.GetViewLocation().Z
      #PROJECTILE SPAWN
      Rocket_LocationX:=Spawned_Rocket.GetTransform().Translation.X
      Rocket_LocationY:=Spawned_Rocket.GetTransform().Translation.Y
      Rocket_LocationZ:=Spawned_Rocket.GetTransform().Translation.Z
      #CALCULATING NEW POSITION
      NewPosition_LocationX:=Rocket_LocationX+(ForwardVector.X*1000.0)
      NewPosition_LocationY:=Rocket_LocationY+(ForwardVector.Y*1000.0)
      NewPosition_LocationZ:=Rocket_LocationZ+(ForwardVector.Z*1000.0)
  
     
      NewPosition:vector3=vector3{X:=NewPosition_LocationX,Y:=NewPosition_LocationY,Z:=NewPosition_LocationZ}
NewTransform:transform=transform{Translation:=NewPosition,Rotation:=Rotation,Scale:=Scale}
Print("Trying to move rocket")
Spawned_Rocket.MoveTo(NewTransform,5.0)

If you just want it to shoot forward from the player, you can set rotation to match player control rotation. It can go in the projectile’s construction script.
You can use Instigator > Get Control Rotation > Set Actor Rotation
Be sure to set an instigator.

You may want to update the tags if you’re looking for C++. It says Blueprint at the moment.

Oh, sorry. It seems I published the thread in the Unreal Engine section. This is UEFN :confused:
