How do I transform an object smoothly

Hi,

How can I transform an object/sprite smoothly? (like growing a button or rotating smoothly)

Thanks!

Increment by dt every tick is a general answer.

Set Sprite scale to 1+dt

Set Sprite angle to Sprite.Angle+dt

Use a multiplier of dt to change the rate.

Thank you!

Can you help with one more thing?

how do I make smooth opacity fade?

Same thing. Set opacity to sprite.opacity-dt

If you want to constrain it so it doesn't go negative, you would do max(0,sprite.opacity-dt)

Alternatively, use the fade behavior.
