library IsWayWalkable initializer Init
// Is Way Walkable system by The_Witcher
//
// well it's a system that checks whether units can walk from a specific rect to another...
//
// FAQ:
// Thats useless!! everyone can let a unit run the way and check whether it reaches the finish or not!!
// - Yes but my system checks within max. 0.3 seconds and it uses no units!!
//
// OK maybe i will use it but for what?
// - Best use is for a TD. It would check whether the creeps can run from spawn to finish
// so you can check whether a player blocks or not...
//
// And how to use it?
// - well just use:
// call IsWayWalkable(spawn, finish) returns a boolean
// rect rect
//
// Ok, ok but how can I import your system??
// - one of the easiest things ever^^
// just copy this trigger in your map and you're done!!

Approved
you are right....
(well....you probably are doing that but it is 11 o'clock in the morning at mine....)
