[Snippet] RangeFromSegment

[Alain.Mark]

	function GetRangeFromSegment takes unit u, real x1, real y1, real x2, real y2 returns real
		local real r=SquareRoot((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1))
		local real a1=Atan2(y2-y1,x2-x1)
		local real a2=Atan2(GetUnitX(u)-x1,GetUnitY(u)-y1)
		if(a1>a2)then
			return Sin(a1-a2)*r
		endif
		return Sin(a2-a1)*r
	endfunction

just a little snippet that checks the linear range of a unit from a segment.

post it at small code snippets ~

it doesn't need to be approved first? :O

No, you post it there and if I "approve of it" then I will link to it from the first post.

 

[Alain.Mark]

ok. :3

Graveyarded on this part, will keep in in Small Code Snippets.
