How do I change scale smoothly

I need to go from 1.3 to 1.0 of my game scale.

I think for this we use dt but i'm not sure how. Anyone?

Thanks.

Thanks man. It's almost working perfectly. I just need to prevent my interface Layer to scale too. Is it possible?

Edit: Nevermind. I just figure it out. Thanks

instead of having it be layout scale change it to layerscale and scale only the layers you want

I just went to layer properties and set scale rate of my interface to 0. Better this way since I need to scale all the world except interface.
