I'm trying to make a scrolling effect for Thrust II. The scrolling basically consists of painting a part of the canvas onto itself. However, it's leaving some garbage behind during the scrolling. Is that not supported? Here's a minimal main.lua that reproduces the problem: lg = love.graphics local c...

Operator error, sorry

This line was the culprit:

To train myself in love.physics, I've made a restricted version of an old (93-ish) DOS toy called Impact . It works, but the problem I'm having is that the system seems to keep losing energy slowly, until eventually everything comes to a stop. Is that a known limitation of the engine? Here's my main...

This thread is older than dirt. This is literally my first thread (probably) on this forum and is 6 years old. I wouldn't even consider trying to go back to this project. And if I did, I'd rewrite it completely and use Bump. Is there any other adventure game engine? I'd love to have a ZZT/MZX style...

Oh, good catch! I reorganized the order somewhat, trying to implement your suggestion of drawing the top layer to the canvas rather than separately, but got distracted adding features and forgot to finish that part. And, well, sorry for the mess, I realize it's a lot of ad-hoc code for the controls ...

Don'tcha love feature creep... :oops: ;) I think your formula to overlay blending might be wrong. There are several formulas called "overlay". I used the one GIMP used until 2.8. I think it's been recently changed in GIMP to match SVG's. I like GIMP's better because it's more continuous an...

Thanks for the video and for the reply. So I did the same as you. Drawing to a canvas and sending the canvas to the shader then drawing a blendmode image. What I've done different is that I draw the image to back on the canvas. I don't know if that is a good idea. That was the next thing I was going...

So I finally got to implementing it in the only way I figured out. I realized that I could use the screen position parameter for the lower layer coordinates that I needed. However, this way feels a bit convoluted. Is there a better way than this? Currently it involves four steps: - draw everything t...

I'm trying to find information of how to implement a composite layer function. By composite layer function I mean a function whose input is two color/alpha component values and its output is a color/alpha component value. Something very similar to love.graphics.setBlendMode but with my own function ...
