Help: Tools


Please send any feedback to   

These tools are designed with a specific animation process in mind. However, you should feel free to experiment and use them to achieve your desired results. We would love to hear any ideas you have for new tools or for improving any existing tools.

While it is not necessary, it is recommended that you use a pressure sensitive drawing device when working with TweenMaker.


The pencil tool lets you rough out a drawing for later clean up with the ink tool. The pencil will only draw on a ruff layer. The harder you press on the tablet, the darker and wider the pencil line will be. The width of the pencil line can be controled via the pencil style window.


Used to erase pencil lines.


Used to draw smooth lines that can be inbetweened between key frames. If you have a pressure sensative tablet, the harder you press, the wider the line will be. The width and style of the line can be controlled via the ink style window.


The edit tool allows you to modify existing lines in TweenMaker. When you move the tool across the screen you will see either a plus , a line , or an angle next to the arrow. The edit tool may also be used on the background level to adjust the positioning, scale and rotation of images.

Selected lines are displayed with a box around them. They can be manipulated as follows:


Painting is done by selecting lines in sequence that define the boundary of color you wish to paint. You paint a shape by selecting all the lines in order that make up the shape. As you do, a preview of what the shape will look like shows up faded on the screen. Clicking on this faded shape will make it solid and complete the painting process. If you make a mistake while selecting lines that form your shape, you can click somewhere else on the screen (where there is no line) to abort making your shape. If you left click on an existing shape, that shape will take on the current paint color. If you click on overlapping colored shapes, a menu will appear that gives you the option of coloring all the shapes under the arrow that color or picking a specific shape to color. Every shape and line has a name that can be changed. See the layers window section to learn how to do this.


Since colored shapes are made up of lines, they will also move along with the bone motion.

When you click on the motion tool, two other tools will appear that can be used to add better motion to your animation: Add Bones and Edit.

Motion: Add Bones

Left click and drag to add bones to which lines may be attached. If you click and drag from an existing point, a bone will be added that shares that joint. The cursor arrow will look like this to let you know your cursor is over a joint.

Motion: Edit

This tool is similar in function and complexity to the line editing tool described above. As you move the tool across the screen, you will see either a plus , a circle , or a bone next to the arrow.
