This is what i thought would be a very simple test…its very basic and easiest to understand if you think of it like an FPS. I have a rectangular prism on the right side of the screen, i have a spawner which spawns a small cube (named bullet, btw) when the left mouse button is clicked. The “bullet” is set to go flying straight forward. There is a rather large cube which the “bullet” will hit. When this collision happens, i want the large cube to disappear.

All goes according to plan except the large cube does not disappear, it just acts like a normal actor. In the logic i have it set to “end object” on collision with “bullet” but it doesnt disappear…what am i doing wrong?

…wow im an idiot. all it took was adding a property to the “bullet” and having the large cube react to colliding with the property instead of the object. sorry for the pointless thread, but perhaps someone else will have the same problem and search for it? maybe? nah that’ll never happen people are too stupid…well, w/e
