bunnymark example - add color to the bunnies

[mvoltz]

I noticed all the bunnies are gray. Two small changes add random colors and alpha to each bunny. (at least it works in linux :)

if rl.IsMouseButtonDown(rl.MouseLeftButton) {
                ...
                b.Speed.Y = float32(rl.GetRandomValue(-250, 250)-500) / 60.0
		b.Color.R = uint8(rl.GetRandomValue(50, 240))
		b.Color.G = uint8(rl.GetRandomValue(80, 240))
		b.Color.B = uint8(rl.GetRandomValue(100, 240))
		b.Color.A = uint8(rl.GetRandomValue(100, 255))
               ...
	}
}
...
for _, b := range bunnies {
        ...
	rl.DrawTexture(texture, int32(b.Position.X), int32(b.Position.Y), b.Color)

If you want, you can create a pull request to update the example :)

Ok I'll do that soon. (note to self - learn more git, esp. pull requests)

Will that affect benchmark in any way, and how is it handled in other bindings? I recently saw a bindings benchmark, so it would be nice if they are all similar enough.

Good question. I'm in the learning phase so my goal was to mimic the raylib example while learning Go. Note: I don't code for a living. 1. One current difference between Go and C examples is the bunnymark graphic. Go binding: wabbit_alpha.png: PNG image data, 26 x 37, 8-bit/color RGBA, non-interlaced Raylib: wabbit_alpha.png: PNG image data, 32 x 32, 8-bit gray+alpha, non-interlaced I'm using a lowly mini pc with an N100 chip to test. With no changes to the source, just the graphic, performance is very slightly improved using the Raylib version. As is, 12-13k bunnies starts to dip below 60fps. The raylib graphic in Go gets a few hundred more bunnies before it dips below 60. 2. Raylib also uses 800x450 resolution for just about every example - Go's example is 1280x960 If I drop the resolution to 800x450 - the bunny count goes up to ~22k bunnies at 60fps. 3. Here's the part i don't understand... I get 75k bunnies before dropping below 60fps with the changes below. Here's the diff between original and my changes. < b.Speed.X = float32(rl.GetRandomValue(250, 500)) / 60.0 < b.Speed.Y = float32(rl.GetRandomValue(250, 500)-500) / 60.0 ---

b.Speed.X = float32(rl.GetRandomValue(-250, 250)) / 60.0 b.Speed.Y = float32(rl.GetRandomValue(-250, 250)-500) / 60.0 b.Color.R = uint8(rl.GetRandomValue(50, 240)) b.Color.G = uint8(rl.GetRandomValue(80, 240)) b.Color.B = uint8(rl.GetRandomValue(100, 240)) b.Color.A = uint8(rl.GetRandomValue(100, 255))

< rl.DrawTexture(texture, int32(b.Position.X), int32(b.Position.Y), rl.RayWhite) ---

rl.DrawTexture(texture, int32(b.Position.X), int32(b.Position.Y), b.Color)

__ I will look at some other bindings to see how they handle this example. Best, Mark
