Line Renderer not showing
So I copied Dani's grappling script and modified it since I am using a character controller. It was working pretty well but when I restarted Unity, my Line Renderer has disappeared! I tried re adding the component but nothing worked.
So I investigated, went back to the video but nothing yet. Then when I was grappling below my map, I found out that the line renderer was stuck at the tip of my main canvas. I had 3 or more canvas'(Is that the problem, no it couldn't. It was working just fine with 3 canvas') So I am stuck with that but I will get back to this forum after. Please reply asap!
