[1.4.6]AutomaPaint 1.1.1 (Turn computers into integrated circuits!))

• Paint Mode

Spoiler

A.K.A: "The Canvas". A pretty generic paint program, paint mode offers an environment where users can set the starting generation for their automaton. Pixel placing is done with the left mouse button, pixel erasing is done with the right mouse button, and pixel color picking is one with the middle mouse button. using the scroll wheel scrolls through all the colors, indicated at the bottom of the screen.

To bring up the main editor menu, press the "ctrl" key. On the bottom of the editor, five buttons, "[L] [M] [T] [X]", will appear. "[L]", "Load", does what you'd expect it to do, it loads a TangentPaint file. Clicking on it will bring up a prompt on the bottom, where you enter the name of your file. Make sure the file is in the same director as TangentPaint, or else nothing will get loaded. "", "Save", is also what you'd expect, it saves all data from the text editor and paint mode "canvas" into a save file. Clicking on it brings up a prompt that you can type in the name of your file. "[M]", "Menu" brings up a menu with a few buttons: "[TXT] [BACK] [START]". "[TXT]", will take you to the text editor. "[BACK]", will take you back to the canvas. "[START]", will take you to the cellular automaton environment.

The "[T]" button, "tools", will bring up a menu containing editing tools. Currently, the only tool in there is the "line tool". To use the line tool, have the color you want to use already selected, and click on the starting point. A "1" with a background of the color you chose previously will appear in the spot. The second place that you click on will draw a line from the "1" point, to the place you clicked. WARNING: Panning while using the line tool has unpredictable results! You have been warned!

The last button, "[X]", simply stops the script, and takes you back to the terminal.

Using the arrow keys in the canvas pans you around. Panning into a place with nothing expands the canvas. Keep that in mind!

• Text Editor Mode

Spoiler

Text editor mode is a rather simplistic text editor, designed to do nothing more than edit the rules for the automatons. To leave this mode, and return to the canvas, press the "Ctrl" key. All changes you make here are automatically saved when you quit. Please take note that any "spaces" in the editor act as a "carriage return", and anything past one will not get saved! Remember, I made this editor for editing a simple CA rule system, not writing pretty attachment notes on images!

• Cellular Automaton Lab

Spoiler

The star of the show, the CA lab allows you to run the CA that you create in the other two editors. The environment is finite, so any gliders that hit the side of the world will act as if they hit a brick wall, and stop. Future version might allow you to run this mode on a monitor.

The new interface for the CA Lab can be brought up with the "Ctrl" key. On this menu, you'll see four buttons: "[#] [BACK] [BACK & SAVE] [START GENERATING]". "[#]" will bring up a (currently a bit buggy) menu that allows you to enter how many generations you want the CA to run. "[BACK]" will take you back to the canvas. "[BACK AND SAVE]" will bring up a prompt asking if you're sure you want to overwrite the canvas with the sandbox. If you hit the "Y" key on your keyboard, the canvas will be over-written with the current generation in the CA. Hitting anything else will close it, and take you back to the CA Lab. "[START GENERATING]/[STOP GENERATING]" Either turns the automatic clock on, or off. The CA will run as fast as it can with this on.
