Increase parameters over time

Hi do i modulate or increase parameters over time ? i.e when i pick up a EXP point object, i want my sprite/character glow horizontally and vertical intensity grow go from 0-100% and back down to 0 over 1 second in a sine wave pattern. Tried using a Sine value hasn't worked, dono is way in value tabs i can dictate a value to grow over time or

Tween behavior is made specifically for this case. You can tween a certain parameter (like sprite opacity), or a numerical value.

But how do I set that to the Intensity of a glow parameter?

You mean a glow effect? You tween a value from 0 to 100. And add another event:

Sprite Tween "tag" is playing : Sprite set "Glow" effect parameter 0 to Sprite.Tween.Value("tag")
