Sprite:hitTestPoint

Available since: Gideros 2011.6
Class: Sprite

Description

Checks whether the given coordinates (in global coordinate system) is in bounds of the sprite.

(bool) = Sprite:hitTestPoint(x,y,onlyvisible,ref)

Parameters

x: (number) the x coordinate to test
y: (number) the y coordinate to test
onlyvisible: (bool) hit test only for visible sprite (clipping/masking) optional, default = false
ref: (Sprite) specifies which sprite is the reference of x,y coordinates. If nil global coordinates are assumed optional, default = nil, new Gideros 2023.2

Return values

Returns (bool) true if the given global coordinates are in bounds of the sprite, false otherwise

Example

Moves a pixel with the mouse

local pixel = Pixel.new(0xff0000, 1, 32, 32)
local x0, y0, focus
pixel:addEventListener(Event.MOUSE_DOWN, function(e)
	if pixel:hitTestPoint(e.x, e.y) then
		focus = true
		x0, y0 = e.x, e.y
		e:stopPropagation()
	end
end)
pixel:addEventListener(Event.MOUSE_MOVE, function(e)
	if focus then
		local dx = e.x - x0
		local dy = e.y - y0
		pixel:setX(self.camera:getX() + dx)
		pixel:setY(self.camera:getY() + dy)
		x0 = e.x
		y0 = e.y
		e:stopPropagation()
	end
end)
pixel:addEventListener(Event.MOUSE_UP, function(e)
	if focus then
		focus = false
		e:stopPropagation()
	end
end)
