Draws a filled or unfilled arc at position (x, y). The arc is drawn from angle1 to angle2 in radians. The segments parameter determines how many segments are used to draw the arc. The more segments, the smoother the edge.
Contents
Function
Draws an arc using the "pie" ArcType.
Synopsis
love.graphics.arc( drawmode, x, y, radius, angle1, angle2, segments )
Arguments
DrawMode drawmode- How to draw the arc.
number x- The position of the center along x-axis.
number y- The position of the center along y-axis.
number radius- Radius of the arc.
number angle1- The angle at which the arc begins.
number angle2- The angle at which the arc terminates.
number segments (10)- The number of segments used for drawing the arc.
Returns
Nothing.
Function
| Available since LÖVE 0.10.1 |
| This variant is not supported in earlier versions. |
Synopsis
love.graphics.arc( drawmode, arctype, x, y, radius, angle1, angle2, segments )
Arguments
DrawMode drawmode- How to draw the arc.
ArcType arctype- The type of arc to draw.
number x- The position of the center along x-axis.
number y- The position of the center along y-axis.
number radius- Radius of the arc.
number angle1- The angle at which the arc begins.
number angle2- The angle at which the arc terminates.
number segments (10)- The number of segments used for drawing the arc.
Returns
Nothing.
Examples
Drawing half a circle
function love.draw( )
love.graphics.arc( "fill", 400, 300, 100, 0, math.pi )
end
Drawing Pacman
pacwidth = math.pi / 6 -- size of his mouth
function love.draw( )
love.graphics.setColor( 255, 255, 0 ) -- pacman needs to be yellow
love.graphics.arc( "fill", 400, 300, 100, pacwidth, (math.pi * 2) - pacwidth )
end
Notes
The arc is drawn counter clockwise if the starting angle is numerically bigger than the final angle. The arc is drawn clockwise if the final angle is numerically bigger than the starting angle.
