If you can't finger that out, you won't know how to use it.
Err my tutorial might help: Right click on the Blockland short-cut then this will pop up:Click "Properties"Then this should come up:Then add " -mod editor" Without the " at the ending of the Target. should look like this:Then click "Apply" then you're done.To use: Just go in-game then click "F10" or "F11" F11 is the mission editor and F10 is a gui Editor/Creator.I hope this helps %100.
