I would like to build a character creation app with next js. This tool should allow the user to alter the character with given slider as well as buttons for the gender.

I would like to have a 2d animated version of the character that is dynamically changed with the input. For example the age slider should change the age of the character and the height should change the height as the slider is moved.

However I have absolutely no idea what the right way is to approach something like this. Of cause I need to create all ne animations before hand, however I am not sure in which way I need to create them. Changing the picture with every movement seems not right. Also I would probably only need to alter parts of the character.

If you have any examples for something like this it would be highly appreciate if you could share them.
