This tutorial describes how to convert a ploppable lot into a reward with reward conditions, optionally difficulty level dependant.
estimated difficulty rating: (https://www.sc4devotion.com/forums/proxy.php?request=http%3A%2F%2Fstudent.vub.ac.be%2F%7Ejjborms%2F4stars.jpg&hash=2aafd93b51766c38507b11baec922e2950092c4a)
As I've already created this in HTML and PDF format I will just post the files for download rather then reconverting them to forum format.
have fun :)
Thanks for the tutorial, but I could not make it work, please try to give more explanations and put more visual examples.
It would be of great help :-)
thanks
