I've made a program where a bar goes up and down the screen, and you have to press the spacebar when it's within a certain area.

For aesthetic purposes, I was wondering whether it's possible to make the 'area' more transparent than the bar underneath, so that you can still see the bar moving up and down?


Thanks!

I just need to make a shape slightly see-through.

Have you tried this?

Ah, that looks like what I'm looking for! Could you possibly explain what it means?

Here you are creating a new color, which is white and is half transparent. The values that you pass to construct a new color are the red, green, blue, and alpha values of the color.
Here you are setting the color to use to draw graphics
Here you are filling a shape with the color you set earlier.
Do note though, that the color will be set for the rest of the draw calls, so you'll probably want to set the color back to solid white unless you want everything afterwards rendered at half opacity.

Thanks!
