You place a warp line in a spot you want to warp (and if you don't want warping, place it in a corner and make walls over it). Then you change the warp direction in the way you want it to look. It will look like it has warp direction, but will only warp in the directions you placed warp lines.
Really? Did you place the warp lines before you changed the warp direction?
Yeah, VVVVVV is kinda weird with that. Sometimes, it will let you insert it just fine, sometimes not.If it doesn't, you have to do it by hand by editing the .vvvvvv file.
so the question has been answered, do we need to lock the thread?
Not if it isn't needed.
