[ H3LP ] Find object?

[CrazY.]

Hello, how I can check if a MovieClip exists in another?

Basically I need to check if a "SolidPoint" (represented by a red X) is "inside" of the object clicked by the mouse and block the player's movement if true.

function CBaseUI_MouseDown(e:MouseEvent):void
{
	// If find SolidPoint in e.target, do not move the player
	_player.moveTo(mouseX, mouseY);
}
