If switching between projects, you can have multiple instances of the Uxn emulator open at various locations. Holding the alt key while clicking on the load-icon, will load the file as a 1bpp sprite sheet.

New file

All changes will be lost, make sure to re-name your file.

Opening a TGA

It is possible to open a TGA file with Noodle. When exporting a TGA from another program, make sure to uncheck RLE compression, and to select 'top left' as origin.

Resize canvas

To resize the canvas, pull on the black corner on the bottom right of the window. Adjusting the canvas size changes the number on top, next to the pattern menu. It's also possible to resize it by clicking alt + arrows.

Only resize the canvas at the start of a project, otherwise it will mess up your drawing.

Erase

It's possible to use the following tools to erase: brush tool, line tool, pen tool and rectangle tool. Select the tool you wish to use as an eraser, press escape key to toggle to erase mode, or click on a brush size in the top menu until it switches to a shape with a contour rather than one that is opaque.

It's also possible to erase using a pattern.

To erase the whole canvas press backspace.

Pattern menu

A set of 8 patterns to draw with. To change pattern select numbers 1 - 8.

The default pattern is black. Select the brush, or rectangle tool first, and then a pattern.

Pen

A tool to draw thin single-pixel drawings on the canvas. The shortcut to select the pen tool is q.

This tool can only ever be 1 pixel. Erase by right-clicking.

Brush tool

A tool to draw brush-like strokes on the canvas. To increase or decrease brush size use the box brackets [ ]. The shortcut to select the brush tool is w. Erase by right-clicking.

To draw using a pattern, select a style from the pattern menu and toggle between each pattern using the numbers 1 - 8.

Line tool

A tool to draw straight lines on the canvas. While the line is red it's possible to change its angle.

Lines will always be 1 pixel wide.

Magic tool

A tool to clean up lines. The shortcut to select the pen tool is r

This tool is useful to remove excess pixels when drawing sharp edges with the pen tool.

Rectangle tool

A tool to draw rectangles on a canvas. The rectangle tool shortcut is t.

To draw using a pattern, select a style from the right menu.

Zoom tool

For a more detailed view of a drawing, select the zoom tool (shortcut is y), or press on the spacebar or shift. The magnifying glass has a little circle next to it when zoomed in.

Use the arrows to move around the canvas while zoomed in, and press the spacebar, or shift key to return to the normal view. If you toggle zoom again after having moved with the arrows, Noodle will remember this new position and zoom in on that exact point on the canvas. If you want to zoom in on another far-away part of the canvas, select the zoom tool and click on the area you wish to modify.
