How to implement animations

[op1337]

How does the workflow support UMG animations? Suppose, I wanted to animate the color of a button when hovered, what is the ideal workflow to achieve this? Can I use it with the UMG sequencer?

UMG animations do not support parameterization directly, so you can't for example have two color variables and animate between them. What you could do instead is have two color variables exposed to style sheets (e.g. Color A and Color B), and use UMG to animate an alpha value between 0 and 1. Then you have two options:

• You can feed all three values into a Material Instance Dynamic and use that to set the final color. This is the best perf, but is more overhead.
• You can create a pure Blueprint function that lerps between the two input colors and set that as a data binding to the color property on the widget.
