I’m sorry to see there hasn’t been an earlier response, but please consider editing your post. Right now you have given us no info on how you’re drawing the lines and no screenshots or diagrams showing what is happening VS what you would expect to happen. You did post your files, but it’s a misspelled .rar file, which I’m sure makes a lot of people a bit iffy about downloading it. Typically you would upload either a .unitypackage, or better yet, just the relevant .cs file(s).
There are a lot of great, friendly, helpful people here, but nobody’s jumping at the oppurtunity to just download (what is presumably) somebody else’s project and spend the first 20 minutes trying to figure out what’s what, and where and what the actual problem even is.
