Snippet: Get vector by using distance and angle from a source sprite

MikeHart Guru

January 2012 edited January 2012 in Code snippets

This is a function, that will determine a vector with a given source sprite, the distance from it and the angle:

getVector = function(source, dist, angle)
	local a = math.rad(angle)
	local x = source:getX() + math.sin(a) * dist
	local y = source:getY() - math.cos(a) * dist
	return x,y	
end
