How to make trigger event to change movement and character model?

Not sure if this is the right place to be posting this

My question is it possible to make a trigger event to change movement controls for example 2d game like Super Mario movement (left and right movement)
and have it change your movement into a 3D space in a 3D world basically like how super paper mario. but I also want to change the players model into a 3D model would this be possible with using a trigger event or how would I go about doing this and making my life easier…

side note I am new to unreal engine thanks in advance :slight_smile:
