The AURA function can be easily added in the Blueprint event graph.

Keyboard example

The blueprint shown below demonstrates how to control AURA-enabled keyboards. (Click here to view full-sized image)

When the game begins, black color is applied to all AURA-enabled devices. Then W, A, S, D keys on keyboard device are set to red color.

Or you can use SetKeyColorEx, SetFKeyColorEx, SetColorByXYEx to set color of multiple keys at once. (Click here to view full-sized image)

Mouse example

There is no "key code" associated with LED's on mice. Instead, the LED's on a mouse are exposed as a 1x3 matrix, so SetColorByXY() should be used.

When the game began, all LED's on AURA-enabled mice become red, and LED's on other devices are set to black.

Animation Introduction

Before using animation functions you need to copy the GIF or PNG files into Content folder of your UE4 game project. Then you just need call PlayAnimation() with proper parameters, the specific animation will be shown on the selected Aura device.

If PlayAnimation() is called again while an animation is being played, the current animation will be replaced by the new one.

Parameters

• X, Y
  Coordinate. Animation will be played at (X, Y) coordinate.
• Length & Loop
  If both Length and Loop are set to 0, the animation will be played infinitely until StopAnimation() or another PlayAnimation() is called.
  If Length is non-zero but Loop is 0, the animation will be played for Length milliseconds.
  If Loop is non-zero, Length will be ignored, and the animation will be played Loop times.
• Speed
  The default speed is 1, which meas the animation speed is as it defined in GIF files.
  The range of Speed is 0~100. The smaller Speed is, the faster the animation will be played.
  For example: Assume that there is one GIF file whose animation length is 10 seconds. If Speed is set to 0.5, the length will become 5 seconds. If Speed is set to 2, the length will become 20 seconds.

Example

Assume you have one Aura-enabled notebook and one Aura-enabled mouse.

Follow the blueprint below:

• When the game begins, all lights on the notebook and the mouse will be set to black.
• If "U" is pressed, the effect of BOOOOM.gif will be played infinitely with 2x speed on the notebook and the mouse.
• If "I" is pressed, the effect of FlashBoom.gif will be played on the notebook, and BOOOOM.gif will be played on the mouse.
• If "O" is pressed, the effect of colorful.gif will be played once on the mouse. FlashBoom.gif still plays on the notebook infinitely.
• If "1" is pressed, all effects on both devices will be stopped, and all lights will be set to black.
