Static methods
staticpointInTriangle(x:Float, y:Float, ax:Float, ay:Float, bx:Float, by:Float, cx:Float, cy:Float):Bool
Returns true if the point (x,y) is inside the given (a,b,c) triangle
staticpointInRectangle(x:Float, y:Float, rectX:Float, rectY:Float, rectWidth:Float, rectHeight:Float):Bool
Returns true if the point (x,y) is inside the given (rectX, rectY, rectWidth, rectHeight) rectangle
staticinlinepointInCircle(x:Float, y:Float, cx:Float, cy:Float, radius:Float):Bool
Returns true if the point (x,y) is inside the given (cx, cy, radius) circle
staticinlinedistance(x1:Float, y1:Float, x2:Float, y2:Float):Float
Returns the distance between point (x1, y1) and point (x2, y2)
staticinlinesquareDistance(x1:Float, y1:Float, x2:Float, y2:Float):Float
Returns the square of the distance between point (x1, y1) and point (x2, y2) It is expected to be used to simply compare two different distances when you don't need the actual distance value (that needs sqrt call).
staticangleTo(x0:Float, y0:Float, x1:Float, y1:Float):Float
Returns the angle between (x0, y0) and (x1, y1) in degrees.
staticangleDelta(angle0:Float, angle1:Float):Float
Returns the delta between angle0 and angle1, all values being angles in degrees.
staticclampDegrees(deg:Float):Float
Clamp an degrees (angle) value between 0 (included) and 360 (excluded)
staticangleDirection(angle:Float, result:Point):Point
Set the given result's x and y values so that it's a vector representing
a direction matching the angle (in degrees)
Parameters:
angle | The angle to compute the direction from |
|---|---|
result | The vector (a |
