Hi everybody !
I introduce here my second project in Lua (after my space invaders) : Bobby Carrot.
It's a mobile game which I try to port to the Nspire.
It's a puzzle game about a little rabbit who has to eat all the carrots of each level.
I made the menu, the sprites, the level displaying and the scrolling. It remains the tiles actions and 48 levels

(I'm going to do a level creator in C)

First, it was going to be my contest entry. But my free version of Nspire student software expires in 18 days, so I give up (I'll have to ask someone to make the .tns for me, and I can't share the code if it's a contest entry)... :'(

The level creator is attached, if you know the game, try it. There's a readme in the ZIP file.

sweet bunny

Is he animated?
I hope so.

Chockosta · « **Reply #2 on:** June 18, 2011, 09:26:51 am »

He's not animated yet, but I hope I'll can do it.

Hope you'll make it.

little hint:
try to make a better change betwen the Plants and the grey place (on the screenshot)

Chockosta · « **Reply #4 on:** June 18, 2011, 09:36:32 am »

Well this could be a good idea, but if I did that, the sprites won't be "mappable" (I really don't know the word)
I'll try that.

Looks very nice indeed!

Very sad to hear that progress may halt because of the loss of student software. :'(

There are other tools you can use to convert the files... they just won't be compatible with OS 3.0.2 until you load it onto your calculator and send it back to the computer.

Looks great!

Chockosta · « **Reply #7 on:** June 18, 2011, 01:01:47 pm »

Yeah, but I have OS 2.0.1 on my calc. (I love oslauncher !)

I finished the level creator (beta).
I attach it in the first post. You can try it if you already know the game...
There's a readme in the ZIP file

Beta version of the game !
You can try the 10 first levels (good luck for level 10).

I didn't add a readme, so here are the controls :
arrows : control Bobby / select the level
escape : quit the current level
enter : select the level.
There are 6 kinds of blocks :
-bush : it blocks you.
-rotating pipes : they rotate 90° clockwise each time you go on them.
-buttons : if you push them, all the pipes rotate.
-spikes : you can walk on them only once.
-carrots : eat them all !
-target : when you have eaten all the carrots, go on the target in order to complete the level.

You can see a video of the level 8 here

If someone could make some maps, It would be very nice

. It's pretty hard to do a good level...

p2 · « **Reply #9 on:** June 19, 2011, 10:49:52 am »

looks great.

but can you try to modify the walking?
It needn't to be animated, but It would look better if the steps aren't like beaming.

Or that the rabbit looks into the direction where he's walking. (Bad english... $:-\$ )

The graphics look really nice. This is why I wish I had an nspire...

Yap, he's taking full advantage of greyscale, like Hoffa did in Pixel Escape. This is getting awesome, nice job

Chockosta · « **Reply #12 on:** June 19, 2011, 01:21:21 pm »

Thanks for the comments !
For the rabbit, I can't make his movement "smooth". It would become too slow.
I could make him looking into the direction where he's walking (I don't know how to say it better

), but I'd have to add 3 sprites. The tns file is already 34 KB heavy. Adding these 3 big sprites would make it ~50 KB heavy. Is it too much or not ?

p2 · « **Reply #13 on:** June 20, 2011, 04:54:00 am »

Good games are large and very good games are very large. That's normal

If it's not too large fot the TI, it's ok.

Chockosta · « **Reply #14 on:** June 20, 2011, 07:41:25 am »

I've just added these sprites, and it's only 40 KB large

And, nice picture ! Bobby is gonna eat you all !
