Spring arm is ignoring collisions

I don’t know how it happened and I cannot find a way to fix it.

This is kind of urgent.

Thanks in advanced

I do not believe your spring arm is supposed to detect collisions. But if you want it to detect collisions, you can set the length of the spring arm and put a collision box around it, then run your collision blueprint off of that.

That doesn’t really help. I’m still new to unreal, and the spring arm did work, but for some reason, it stopped. It’s the default spring arm in the engine, I don’t know where its collision detection blueprint is.
