Hello !
I make levels for nSMM 0.7.4a
Enjoy this ! 

These levels are enjoyable, thanks for creating them
I hope to implement course world at some point, and I'd like to include some levels, you should join the discord 

On my Ti-nspire CX II, the on.paint function only runs when I click the page number. It works fine on the student software.

I won't pretend I know how this really works, but the way I see it the paint function is called when events are triggered, and also when platform.window:invalidate() is called. You can add this code and it should refresh automatically without input:

timer.start(0.01)
function on.timer()
        platform.window:invalidate() --refreshes screen
end

Be warned about using this method though, switching off the handheld while the timer is running will cause it to freeze.

Progress is currently coming along nicely, with a plethora of additions since I last replied here. These include but are not limited to:
- piranha plants
- multi coin blocks
- fire flowers and stars
- decorations
- a hud

The full changelog since 0.4.0a is presented here:

0.6.1a (28/08/22):

- added invisible blocks
- major reshuffling of block ID's
- more accurate death anims for when hit by fireball/star
- added piranha plants with variants for 4 directions: up down left & right
- added multi-coin blocks
- made the block bounce animation twice as fast (4 frames) to give the illusion that it is less clunky (it isn't)
- fixed 50/50 chance of being invisible when powering up during iframes
- fixed despawing (...not actually despawning)
0.6.0a (22/08/22):

- new blocks:
   ~ entity only block -> solid to mario but lets everything else through
   ~ mario only block -> reverse of entity only block
   ~ coin ? block -> get coins
   ~ coin brick block -> get coins
Truthfully, I would appreciate interest in this project, as so far no one has given feedback on this. There could be some obvious issues that I don't encounter that would improve it. You can join the (miniscule) community here. Updates are posted there, but 0.6.1a is attached here too.

Hi Chalex,
Please continue on the good work, it helps your neurons stay healthy, and maybe invite others to do likewise.

Uh, thanks! Neuron health is one of my priorities at this time indeed.

While my modification to Minecraft 2D is all but dead in the water, I've decided to take up my own project from scratch. Yes, I've had the terrible idea of making a platformer in Lua. Due to it running like piss due to hardware (and in my opinion deliberate) limitations, several compromises have been made:

First, the framerate is awful. I haven't measured it but it's pretty bad. In it's current state it's surprisingly very playable (could just be me used to it though) but as more features are added it will inevitably worsen. You are free to suggest and/or implement optimisations to my shoddy code if you like, it would be very much appreciated!

Secondly, TI-nSpire Lua does not support holding down buttons, except for arrow keys. This means that in order to maintain an input the button has to be repeatedly pressed. It does not have to frame perfect as I coded a timer which makes every press last longer. The arrow keys would be theoretically fine for movement as that's all that requires constant pressing, but there is a significant delay between initial press and it turning into "held button" mode that is not good enough. Both arrow keys and keypad buttons are supported and it's up to the player to decide which is less bad.

Why not code it for ndless? Because I like making my life difficult.

With my manifesto dealt with, you can download the latest version from Github (which I don't know how to use) or the Discord server I created (which I know how to use):

DISCORD
(contact me here if you want to contribute or you have a query)
GITHUB

CURRENT STATUS:
Basic level collision is finished. Enemies and death are working. Mushrooms work. There is no editor but blocks can be placed ingame (temporarily)

FUTURE:
I intent to make the original SMB on the NES playable by remaking the objects from there as a priority. There are no plans for other styles. A main menu will be made at some point along with a saved levels menu (after a significant portion of the game is done and the editor is made). A standalone application to save exported levels will be made too with the idea of housing a set of levels made by someone to be downloaded and played.

The latest version as of writing is attached but will become quickly outdated, I may periodically post newer versions.

You'll want to use the ti nspire scripting tools to convert images to the ti.image format

Hey! I was wondering if you would like some help? I’ve attempted something like this in the past, but I couldn’t figure out how to open the code up, but considering someone else is doing it I wanted to help. I’ve been programming for about 3 years now so this shouldn’t be that hard to work with. If you would like some help, you can just reply to me here, but it would probably be easier to email me at [email protected] as I will be able to respond quicker there. Also, attacking endermen crash your game, check on line 2018 for a null value .

Editing the code is easy providing you have the student software, you just need to click Insert>Script Editor>Edit Script. I don't know anything about coding myself honestly, I coded for 5 years in Scratch and now that I'm older I'm translating my knowledge into written code (which meant stopping the use of hardcoding, endless if statements and endless loops - but I at least understand the fundamentals). This is really the first time I've touched real programming and for that reason, I feel I'd frustrate both of us if we both worked on it. You are however free to try and patch something better from my code, but I also don't want to feel guilty of throwing garbage to you to fix .

And the error on line 2018, that has something to do with teleportation.

function AbstractMob:teleport(x, y, distanceX, distanceY, rangeX, rangeY)
    local searchX=0
    local searchY=-100
    local searchNum=math.random(0,1)
    local attempts=0
    while (world[searchX][searchY].solid and world[searchX][searchY+1].solid) and attempts<=9999 do --LINE 2018
        searchNumX=math.random(0,1)
        searchNumY=math.random(0,1)
        if searchNumX==0 then searchX=math.random(x-distanceX-rangeX, x-distanceX)
        else searchX=math.random(x+distanceX, x+distanceX+rangeX)
        end
        if searchNumY==0 then searchY=math.random(y-distanceY-rangeY, y-distanceY)
        else searchY=math.random(y+distanceY, y+distanceY+rangeY)
        end
        attempts=attempts+1
    end
    if attempts<=9999 then
        return searchX, searchY+1
    else
        return x,y,2
    end
endThe code checks random areas for an area to teleport to within a certain range and if its in a hole for example the attempts var exceeds 9999 then it doesn't move.
I don't think I can reproduce that error as well, perhaps you remember the circumstances that it occured in? I never got an error like that in my testing.

I've split this into it's own topic.

Thank you

New update!
I am releasing the v2 version Chalex's MC2D Mod!

Textures look bad due to being taken with an emulator!! They look crisp on hardware!
A showcase of all the new blocks!



Strongholds now have a 1 in 10 chance of generating in place of dungeons!



Fixes:
 - Hamster changed to glowstone
 - A few crashes fixed


New!:
 - Strongholds generate in place of 1/10th of a dungeon! They contain an end portal and some stairs. Once I manage to make a new dimension I might even be able to implement the End
 - New stone brick block types!:
    - Stone Bricks (craftable from 4 stone)
    - Mossy Stone Bricks (craftable from 1 vine and 1 stone brick)
    - Cracked Stone Bricks (craftable by smelting stone bricks)
    - Stone Brick Stairs (craftable from 6 stone bricks)
 - Other new blocks!
    - Vines (obtainable as chest loot and act like ladders)
    - Iron bars (craftable from 6 iron)
    - End portal frames (not craftable)

Bugs :
 - Sometimes the roof of strongholds spit an error. I have no clue why.


Future:
 - The end!
 - Valuable blocks (block of iron, gold etc)
 - Nether Portals to teleport to the "Nether" layer!
 - Endermen!
