I have put the public static bool on my form1
What i do now to check if the player is on my poligons and where i put the export of the program?

you need a "Is in Polygon" function.

Like for example; http://assemblysys.com/php-point-in-polygon-algorithm/

I have no experience with your program language, neither I would like to because Microsoft but like he/I said... You need to build a IsInPoly function.

I have no idea about this example, I code in .NET

i have no idea about all my tools and programs, i code on potato

How I check if the player is on the polygon?

https://github.com/turbosnail/lfspolygon

look at c# code
Check_Pos (count of points, array of x points, array of y point, your x position, tour y position)

Is it so difficult to guess? If you want to be a developer, you must be able to find what you need, and not ask others to write everything for you.

Yes mate, sorry for asking but I am so noob with functions.
It is the first time I am working with it

I've submitted a couple of bugs on Github, other than those it seems to be working just fine.

@kristofferandersen fixed =)
