bullet
As the Delay node is broken for my current version of Unreal Engine, I had to find a way
to ask the bullet to wait for a while after it is spawned and then destroy itself.
The best and most efficient way to fix the Delay node was using a timeline node and set-
ting its duration to 4 seconds. Then, when the animation finished, I called Destroy Actor .
The rest of the calculations of the bullet were done using OnComponentBeingOverlap
and checking the overlapped components.
If the overlapped component had an enemy tag then I just called Destroy actor to destroy
the parent actor that holds this component. Finally, I used a quick search method such as
Get All Actors Of Class to look for the uiText class and called its setScore custom event
to add 1 to the score and the UI.
