So I have used the code of this website for drawing filled triangles. But I would like to improve my game by adding the illusion of color. Well sadly I made my game for the monochrome Nokia 5110 screen which can't draw just one pixel but needs to draw lines. So I though about a concept like that: I could enter a float into my fill triangle function (0-1 = 0-100%) and if I for example enter 0.5 then it will only draw 50% of all the pixels. This would be possible by always leaving a small gap when drawing lines. (I don't care if it starts glitching at for example 1 - 10 percent)


So it turns out that I am just way to dumb to create such an complicated filling method. Is this even possible? Thanks in advance!

Epilogue : You don't really need to create this whole function. Just a little tip or link to an already existing method will help. But thanks if you decide to create it anyway :3

  • \$\begingroup\$ I don't want to see the code you referenced, I want to see the code you wrote. Your question is tagged c++, not Java, so presumably you've had to do some translation from the reference. Show us your translation. \$\endgroup\$
