Hi,
I need to resize a image for a crosshair. The crosshair should have the size of the screen (sniping-zoom).
Code: Select all
Dim Scope As Irrlicht.Video.ITexture
driver = Device.VideoDriver
driver.Draw2DImage(Scope, New Core.Position2D(0, 0), New Irrlicht.Core.Rect(0, 0, 1280, 1024, New Irrlicht.Video.Color(100, 255, 255, 255), True)
This work but only for a screen with 1280x1024 Pix.
Thank You

The easy way out would be to draw an image of the crosshair's outline and then center it on the screen and render black pixels all around it. Something like:
(pseudocode because I don't know .net)
Code: Select all
load image of crosshair; (put black around it in a square and use white for transparencies!)
load image of one black pixel;
crosshairX = (XRes / 2) - (half width of crosshair);
crosshairY = (YRes / 2) - (half height of crosshair);
then in the draw loop
if (scope == true)
{
draw(crosshair, (crosshairX,crosshairY));
draw(black, (0,0), rect<s32>(0,0,height of crosshair, YRes)
//^^Repeat above until all four sides are covered
}
The problem with this method is that the crosshair will appear smaller on higher resolutions.
You could also have an image for every supported resolution...
