This rectangle drawer uses 100% pen to draw you a filled out rectangle. Click on the first corner and the second corner after 0.5 sec (no need to be exact it is coded like this to prevent bugs) Pros: No glitches no lags
Feel free to use the script in your projects! I made this because I have only seen non-filled out drawers and the ones which do fill out are glitchy. Note: It draws it slowly to prevent glitches and round edges.
