__NOTOC__
This function takes a set of XY coordinates, a distance and a rotation argument. It returns XY coordinates of the point that is the given distance away from the given point, in the given direction.

==Syntax==
<syntaxhighlight lang="lua">float, float function getPointFromDistanceRotation(float x, float y, float dist, float angle)</syntaxhighlight>

===Required Arguments===
* '''x''': The X coordinate of the starting point.
* '''y''': The Y coordinate of the starting point.
* '''dist''': The distance from the starting point to the target point.
* '''angle''': The direction from the starting point to the target point.

==Code==
<section name="Function source" class="both" show="true">
<syntaxhighlight lang="lua">
function getPointFromDistanceRotation(x, y, dist, angle)

local a = math.rad(90 - angle);

local dx = math.cos(a) * dist;
local dy = math.sin(a) * dist;

return x+dx, y+dy;

end
</syntaxhighlight>
