hi, im new in making games what method that use for make our character can run on its own? Like Jetpack Joyride Game in Play Store. Sorry for the bad english, im using google translate.
You make an animation of a character running, and then just play it. Write a bit of script to detect inputs from the player, and use this to change the character position and/or animation. I have an article on 2D animation techniques in Unity that might be helpful. I apologize that it is only available in English. Please also see this handy Getting Started FAQ.
