Hi! I just started digging into Dragonruby. I'm really liking the straightforwardness of the API so far.
The first thing I wanted to do was try out some simple spritesheet-based animation. So I had a look in mygame/documentation/05-sprites.md and found the "Sprite Sub Division / Tile" example there. But when I tried it out, with my own spritesheet, nothing got rendered to the screen. After some experimentation I found that if I don't set source_h, or I set it to `-1` like other parts of the docs suggest, then I get the all the way to the bottom edge of the image rendered, as expected. But then If I set it to a positive number like 32 then the image does not show up at all.
Here's a small code example that demonstrates the issue for me:
def tick args
args.outputs.sprites << {
x: 100,
y: 100,
w: 100,
h: 100,
path: "dragonruby.png",
source_x: 0,
source_y: 0,
source_w: 32,
source_h: 32
}
end
As is, this shows a blank screen, but if I remove the source_h line, then I see part of the dragonruby logo as expected.
