GamePlay Question

Mechanic Question

How do I go bout a 2d side scroller game? Like old school contra? Or like a metal slug ?

Do I just adjust the camera to a side view of the hero and have the camera follow here through 2d space?

Can any elaborate or point me in the right direction? thank you. logic or advice. thanks.

make an orthographic camera, put it to the side of the player and make the player it's parent. Then you'll need a movement script for the player, but this way the camera will move completely with the player, no smoothness.

Have a look at this tutorial for 2D games in Unity.
