A-to-Z Nspire Lua tutorials

This page links to Steve Arnold’s website where you can find excellent detailed, step-by-step tutorials.

However, they are all in English. Inspired-Lua is making its best to translate them into French too.
The french version so far is available here.

Lesson 5: Putting it all together: Some Applications
page setup template, simple quiz document

Lesson 6: Quick Start: Controlling a Point on a Graph page
on.arrowUp, on.arrowDown, on.arrowLeft, on.arrowRight, on.create, timer.start, on.timer
Lesson 7: Quick Start: Working with Images in Lua
image.new, drawImage, image.width, image.height, image.copy, on.resize
Lesson 8: Quick Start: Getting Started with Graphics in Lua
drawLine, fillRect, fillPolygon, drawArc, fillArc, isColorDisplay, setAlpha
Lesson 9: Graphical Shape Numbers
Drawing an array, and varying the grid pattern
Lesson 10: Taking Shape Numbers Further
Putting it all together, on.escapeKey, on.tabKey

Lesson 11: Introducing Classes
class, init, contains, paint, selected, color table, unpack
Lesson 12: Mouse Controls with Classes
on.mouseDown, on.mouseUp, on.mouseMove
Lesson 13: Keyboard Controls with Classes
Using arrowKeys, enterKey, tabKey and escapeKey with classes
Lesson 14: Keyboard Controls with Multiple Classes
Using a table to define multiple classes, #Objects (dimension of table Objects)
Lesson 15: Mouse Controls with Multiple Classes
TrackOffset variables, table.remove, table.insert, cloning selected class objects

Lesson 16: Further Useful Tips and Tricks I
Useful string commands: find, replace (gsub), split: applied to pretty print function for algebra
Lesson 17: Further Useful Tips and Tricks II
math.eval (and all applied to fraction function along with a template for multiple keyPads)
Lesson 18: Further Useful Tips and Tricks III

The lessons in this next section require OS 3.2 functionality.

Lesson 21: (3.2) Text Boxes and Rich Text Input
The new and better way to enter and work with text as the user inputs it: Rich Text boxes come alive!
Lesson 22: (3.2) Create Your Own Math and Chem Boxes
Displaying and evaluating mathematics has never been easier now that we can let TI-Nspire MathBoxes take care of the heavy lifting!
Lesson 23: (3.2) Welcome to the Physics Engine! (I)
Based upon the open-source Chipmunk Physics Engine, this powerful new feature adds amazing possibilities to your Nspire scripting and is the perfect tool for creating simulations of all sorts.
Lesson 24: (3.2) Welcome to the Physics Engine! (II)
Bouncing a ball around the screen maybe a very simple simulation, but it can be the start of something much bigger.
Lesson 25: (3.2) Welcome to the Physics Engine! (III)
Bouncing multiple coloured balls around the screen is much more fun.
