I used to do zoom in and zoom out using camera plugin, but with construct 3 there is not.. so how to make a smooth zom in and zoom out efect?
Develop games in your browser. Powerful, performant & highly capable.
To instantly zoom you adjust system 'scale' and to do it gradually I guess you add or subtract to the scale value over X seconds.
You can scale layout. Use a lerp for a cool effect.
