Incrementally increase jump z velocity

I’m trying to create a pickup that increases the players jump height, and I need the effect to stack as you collect more. the blueprint i have so far increases my characters jump height just fine, it just won’t stack. Any help is greatly appreciated, thank you.

Looking at your blueprint you are just setting JumpZVelocity to 1000 when you collect one of your items, you’re not stacking values.

Something like this should do the trick (get current JumpZVelocity, add some power and set it again, i inserted a clamp to stay safe with huge or negative values)

Thank you very much!
