Well, Lua development certainly has slowed down a bit. Anyways, I now introduce my latest project, Runner Jumper! It's kinda based off Canabalt. You run across the rooftops and go as far as possible. Although you don't see in the screenie, it gets faster as you go on.

Hiscore actually works with this program. I have been programming on-calc, so the program is being run on nspire_emu with oclua.

I'm probably going to add a better, moving sprite. Dimensions are 10*15 if you're interested.

Screenie is attached and suggestions are welcome!  Smiley

Edit: I just noticed how choppy the screenshot was. It's not actually that bad in the game Tongue

Sounds pretty cool. Are the stick-based graphics due to speed issues or are you planning to switch to sprites/tiles in the future for buildings?

Good luck with this project!

Lua developpement has indeed slowed down, and that's sad.
I hope there will be a lot of new projects during summer vacation...

Yeah, the graphics are going to be upgraded sometime...

Well, here's a version I put together with some sprites. It looks pretty nice, but the program runs noticeably slower... Any ideas on making it faster?

Spoiler for Still Alive:
This was a triumph.
I'm making a note here: HUGE SUCCESS.
It's hard to overstate my satisfaction.

Aperture Science:
We do what we must because we can.
For the good of all of us
Except the ones who are dead.

But there's no sense crying over every mistake
You just keep on trying till you run out of cake
And the science gets done and you make a neat gun
For the people who are still alive.

I'm not even angry.
I'm being so sincere right now.
Even though you broke my heart and killed me.
And tore me to pieces.
And threw every piece into a fire.
As they burned it hurt because
I was so happy for you.

Now these points of data make a beautiful line
And we're out of beta we're releasing on time.
So I'm GLaD I got burned think of all the things we learned
For the people who are still alive.

Go ahead and leave me.
I think I prefer to stay inside.
Maybe you'll find someone else to help you.
Maybe Black Mesa -
THAT WAS A JOKE. HA HA, FAT CHANCE.
Anyway, this cake is great:
It's so delicious and moist.

Look at me still talking when there's science to do.
When I look out there it makes me GLaD I'm not you.
I've experiments to run there is research to be done
On the people who are still alive

And believe me I am still alive.
I'm doing science and I'm still alive.
I feel FANTASTIC and I'm still alive.
While you're dying I'll be still alive.
And when you're dead I will be still alive.

Still alive
Still alive

Do you create the view of the buildings with rectangles, or is it an image? because if it were an image it would be quite slowing down indeed Smiley

Right now I just use some images, but they're tiled. I just realized that the picture is simple enough to just use rectangles! Yay! Cheesy

When displaying sprites, do you redraw them every frame or do you just shift the screen around and only draw the missing parts? The latter, if possible in Lua, might be faster. Also this looks nice Smiley.

Attached is an early, but not fully finished build. It has the basic running and stuff so you can has some fun.

I might include features of Canabalt like cranes, billboards, birds?

The falling platforms, bombs, and boxes will be more difficult...

Hope you enjoy!

That is a pretty interesting article, but yeah I fixed the speed problem. Drawing rectangles is a LOT faster than images...

I plan on adding parallax scrolling in the background for depth, that'll probably be the easiest feature to add right now.
