Owl — A fast, lightweight, and flexible game engine for the TI-Nspire

[ExtendeD]

hoffa, could anything done with Ndless Lua extensions to improve the engine?
An alternative to the default key press detection?
Scrolling?
A wrapper to nRGBlib's drawTile8Multicolors()?

Those things definitely could be used, but maybe we could try to improve the functions/event stuff TI made, so we keep compatibility.
I guess this is a bit more complex, but it might be worth the try

dang, I really have to learn Lua X.x

EDIT Weird I don't notice much of a frame difference. Is it just due to the getkey speed limitation and lack of smooth character movement?

Actually I just noticed that that TNS used the timer to refresh the screen every 0.01s (I was measuring the FPS), rather than updating after moving Link (I uploaded again and updated the link). I think why it doesn't seem to be that much faster is because of the key repeat limitation indeed. Also if I had used a map with loads of sprites you would have seen a huge improvement, but even now it should be quite a bit more responsive.

You should make a demo where the character gradually moves from a tile to another like in some RPGs. I wonder how smooth it would be on-calc.

I did this: a smooth tile by tile movement a la Pokemon, I thought that would be hard to code, but no!

I made something like this

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7

If getkey Set movement distance in one var End Else Move by one pixel along the direction Decrease the movement variable

The trick is to define movement if only the movements variables (not the positions) are null.

[DJ Omnimaga]

In Lua you mean? Because the issue in Nspire Lua (for now) is that there could possibly be some delay between each moves. It would be nice to test, but if the character moves smoothly between tiles, but stops for 0.1 second between every tile, it probably won't look great unless you have a walking animation where your sprite does two step between each tile and the animation shows him stop for a bit in the middle of a tile.

Made That with axe, but should be easily portable...

[Jim Bauwens]

Well, what I did in my bombermaze thing is move the character 4px (or a bit more) each time you press.
But this is done smoothly, using the timer. So, it feels quite responsive and looks good

Oh wow didn't notice there were new posts here. Owl is on hold while I work on the SDL port, so don't expect any updates right now.

I think I'll keep this project as TI-Nspire's official Lua only.

It's ironical; I found the NK propaganda videos very amusing. Beware of anything I say. I'm also supporting the Free People of the Democratic People's Republic of Korea in their heroic struggle to crush the American Imperialists.
