Examples
| Description | This example will draw a crosshair in the center of the screen. |
|---|---|
| Used on | |
| Code | --gets the center of the screen local x = ScrW() / 2 local y = ScrH() / 2 --set the drawcolor surface.SetDrawColor( 0, 255, 0, 255 ) local gap = 5 local length = gap + 15 --draw the crosshair surface.DrawLine( x - length, y, x - gap, y ) surface.DrawLine( x + length, y, x + gap, y ) surface.DrawLine( x, y - length, x, y - gap ) surface.DrawLine( x, y + length, x, y + gap ) |
| Output | Draws a crosshair. |
| Description | This example will draw a pixel perfect circle. |

| Used on | |
| Code | hook.Add( "HUDPaint", "Circle", function() local center = Vector( ScrW() / 2, ScrH() / 2, 0 ) local scale = Vector( 100, 100, 0 ) local segmentdist = 360 / ( 2 * math.pi * math.max( scale.x, scale.y ) / 2 ) surface.SetDrawColor( 255, 0, 0, 255 ) for a = 0, 360 - segmentdist, segmentdist do surface.DrawLine( center.x + math.cos( math.rad( a ) ) * scale.x, center.y - math.sin( math.rad( a ) ) * scale.y, center.x + math.cos( math.rad( a + segmentdist ) ) * scale.x, center.y - math.sin( math.rad( a + segmentdist ) ) * scale.y ) end end ) |
| Output | Draws a pixel perfect circle on the screen. |
