i programming small game. i've made character moving tilting phone. i'd character ( image spritenode ) jump, when touch screen. still want him move left , right when tilt phone while jumping. best way it? thinking making physicsworld , give him mass , activate gravity. but how let him jump once when touch screen? i'd happy answers. thanks. the question is: do need physics ? it depends on want game physic makes game more realistic, need? does ground has slopes? is there caves or several floors? can pass through floors while jumping up? ( doodle jump style ) your character have velocity associated, vector x , y speed. velocity applied each frame of game loop. simulate gravity, remove small amount of y velocity, begin fall down progressively, faster , faster. if want make character jump, apply relatively high amount of y velocity. you may want subclass sknode add velocity property, can know , apply position in game loop, think apply existin...
