Old games used a technique to animate textures where they shifted the sprite one row or column per frame. An easy/cheesy way to do this is to just produce a set of sprites that are shifted already and treat them as individual frames.
I want to see if there's a way to do it without duplicating and modifying the sprite. I'm thinking that ancient platforms (think Commodore C=64 or Apple ][) wouldn't have the memory to waste for this sort of thing.
The goal is to do this with one draw call, rather than two. You can use the
texture's wrap mode (via setWrap()) to make it infinite.
You can run it from this directory with:
./love .If you're using Sublime Text:
- Open the project.
- Under Tools -> Build System, choose "Launch Löve2D". You only need to pick the build system once, it's stored in the workspace file.
- Choose Tools -> Build or press its shortcut (Ctrl+B).
Press Escape to exit the demo.
This is written in Lua, using the LÖVE 2D game engine. I didn't know about that until I stumbled on CS50's Introduction to Game Development.
