Just wondering how to make a counter that goes from 1 to 100 when a key is pressed. In the same way, counting down from where the previous count was set to 1 when another key pressed. This function will feed the intensity of a point light.
Another use for this function will be to vary the RGB value of a series of spot lights. The spot lights will represent an LED RGB strip.
Make the lights in your blueprint either Dynamic or stationary lights, then either set the variable + or - on press or use a timeline with a float track to drive it, and use the set colour node to take care of that.
Hopefully it helps
