I am working on making a JavaScript library to help people transition from TI-Basic to JavaScript. I have only made a text() command and a dispScrn() command. dispScrn() is used to create the screen area so all other commands work.
I'll work on a tutorial soon, well after I make a few more commands.

nice will this be some new language that is parsed as javascript but has a syntax like TI-BASIC? It would be nice to be able to do web apps this way

no, its a JavaScript library, so kind of like added commands that are more familiar to TI-Basic users. It will also have it's own look and everything that will remind you of the TI-Screen.

EDIT: added a pixelOn() command, so now you have basic drawing capabilities

EDIT2: added a sprite() command for displaying images anywhere and at any size.

Tutorial

Code: [Select]

<html>
 <head>
  <title>
   Page Title
  </title>
  <script src="jBasic.js"></script>
  <script>
   function setup(){
    //Place code here.
   }
  </script>
 </head>
 <body onload="gScreen = document.getElementById('window');setup();">
  <div id="window">
  </div>
 </body>
</html>

Use this basic setup and place any JavaScript in the '//Place code here.' line. Add any content you want between the <body> tags

Commands

dispScrn(w,h,x,y)
creates the window that the content is displayed in.
w = width in pixels
h = height in pixels
x = x location from the left of the screen in pixels
y = y location from the top of the screen in pixels

text(x,y,size,text)
Writes text on the screen.
x = x location from the left of the screen in pixels.
y = y location from the top of the screen in pixels.
size = text size in pixels
text = text content, can include html code for more advanced purposes.

pixelOn(x,y,color,w,h)
creates a block on the screen.
x = x location from the left of the screen in pixels.
y = y location from the top of the screen in pixels.
color = color of the block, can be in hex or named.
w = width in pixels
h = height in pixels

sprite(x,y,w,h,src)
places an image on the screen.
x = x location from the left of the screen in pixels.
y = y location from the top of the screen in pixels.
w = width in pixels
h = height in pixels
src = the source of the image, can be a relative URL or a direct link.

Nice, seems like it could do some interesting stuff

Eeems · « **Reply #5 on:** April 30, 2010, 08:07:13 pm »

Thanks

I've put way too much time into figuring out the basic stuff

I'll be adding more later, and I'll probably make an extended set for more functionality as well

Cool

* DJ Omnimaga hopes Eeems didn't kill his calc projects including ADE, tho o.o

Eeems · « **Reply #7 on:** April 30, 2010, 10:00:33 pm »

Well ADE kind of already died, but i haven't killed my mario physics engine yet. I'm just focusing on projects that get me marks at school right now.

DJ Omnimaga · « **Reply #8 on:** April 30, 2010, 10:08:30 pm »

aw sorry to hear

why did you kill it btw? I hope you aren't slowly quitting calc stuff

Eeems · « **Reply #9 on:** April 30, 2010, 10:25:02 pm »

I killed it because i needed to get on to more projects so i can get my full credits in computers. I may come back to it later though.
No I'm still into programming calcs, but i dont have the time to do it much right now.

DJ Omnimaga · « **Reply #10 on:** April 30, 2010, 11:04:31 pm »

Oooh ok phew, I was getting worried since most of your posts in the last month were non calc related. I hope when school is finished that you can do calc stuff again (and get your calc back)

Eeems · « **Reply #11 on:** May 01, 2010, 12:52:38 am »

Don't worry, I'll code for calcs for a very long time. Its what got me started on programming after all :p

I just added a line() command and a clrGraph() command as well.

line(Ax,Ay,Bx,By,w,color)
Draws a line on the screen.
Ax = the initial x location in pixels
Ay = the initial y location in pixels
Bx = the second x location in pixels
By = the second y location in pixels
w = the width of each line piece on the line
color = the color of the line. Can be hex or color name.

nice

Galandros · « **Reply #13 on:** May 01, 2010, 03:25:44 am »

Interesting. For now the code will look much like JavaScript but later when you added most stuff, it will be similar to BASIC, I think.
Don't forget to bring the Math.functions to a normal function.

I will keep updated about this.

I wonder, in Javascript, are there any possibility of interaction from the user by pressing keys? Otherwise I guess a point and click game could be awesome too when it has more commands
