When I tried to use code (using the old input system) to enable/disable emission, the lasers would only fire for the first second or two of play and then stopped. The emission box would still flick on and off and the console still showed “shooting/not shooting”, but no lasers appeared.
I couldn’t figure out the problem, so I just reverted to when the laser trails disappear when the player stops pressing the button. Someone else seemed to have this problem so I’m just posting in case it keeps happening to people.
