Ethanon Editor
The Ethanon Editor allows developers to visually compose, configure and edit entities and particle systems that are attached to entities. Also create entire scenes and see how they are going to look like in real-time.
The Editor is divided into three main tools: ParticleFX Editor, Entity Editor and Scene Editor.
Editor tools have numerical input fields that allow using the mouse scroll wheel to gradually increase or decrease their values by scrolling up or down.
The screenshot below shows three numerical input fields. The one in the middle is selected:
Using the mouse wheel is recommended for editing whenever possible since it allows the user to gradually see the effects of the change.
