示例1: Line
// Draw a line
func Line(screen *sdl.Surface, x1 int, y1 int, x2 int, y2 int, color sdl.Color) {
if x1 == x2 || y1 == y2 {
return
}
startx, stopx := minmax(x1, x2)
starty, stopy := minmax(y1, y2)
xdiff := stopx - startx
ydiff := stopy - starty
if xdiff > ydiff {
// We're going along X
y := float32(starty)
ystep := float32(ydiff) / float32(xdiff)
if y1 != starty {
// Move in the other direction along Y
ystep = -ystep
y = float32(stopy)
}
// Draw the line
for x := startx; x < stopx; x++ {
screen.Set(x, int(y), color)
y += ystep
}
} else {
// We're going along Y
x := float32(startx)
xstep := float32(xdiff) / float32(ydiff)
