The missing script wizard for GMS2 :) <3
GML Script Wizard
GML Script Wizard is a tool for GameMaker Studio 1.4 and 2 that automatically generates boilerplate headers you can use as your script's starting point. Easily add, remove and reorder arguments and local variables in your script header. Once you are happy with it, copy it to the clipboard with the click of a button and paste it into the GML code editor of your choice.
