This document outlines how to use the Brush Ninja animation creator, and covers some of the more advanced features that may not be immediately obvious.
The editor is divided into three sections.
- The big white square is the current frame. This is what you should draw on.
- The group of circles are your brushes. The different sizes represent the size of the brush. Click to select the size you want.
- The group of colours are the paint colours. Click to swap between colours.
Underneath the frame canvas is a control panel. From here you can change the animation settings, and play the animation.
Playing the animation is as simple as pressing the play button. When you do this all of the controls will fade out so that you can focus on watching the animation. To bring the controls back press the play button (which will have changed to a stop button).
The timeline shows the frames that make up your animation. Each frame will be displayed for a fraction of a second before showing the next frame. By default only one frame will be displayed. Click the big green ‘add frame’ button to add more frames.
To change the selected frame in the editor simply click the frame you want to work on.
Under each frame in the timeline we have 2 buttons. The 2 documents copy the frame. The trash can deletes the frame.
You can also drag and drop frames to change their order. This also works with the add frame button. The advantage of being able to move the add frame button is that you can add new blank frames wherever you like.
Note that you must always have at least one frame in the timeline.
