slide

问题 I want my sprite to slide like he's on ice. So if he's on ground then he can walk normally, but when he touches ice he will slide until something stops him. Does anyone know how one can do that? Thanks 回答1: Manipulate the friction coefficients like the "Sprite Movement Towards a Target" example (modified below): class Sprite(pygame.sprite.Sprite): ICE = 0.01 LAND = 1. def __init__(self): # ... self.normal_friction = .95 # friction while accelerating self.slowing_friction = .8 # friction while

问题 I am currently fading out the content of a div, replacing it with new content, and then fading it in again as follows: area.fadeOut('400').load("file.php", function(){ $(this).fadeIn('400'); } ); First of all, is this chained correctly?

问题 EDIT: What is the animation name of the gif below (from right to left)? What is the animation name of the complementary animation of the gif below (from left to right)? NOTE: I don't want to push a segue. I want to push a view with that animation. EDIT 2: Some people are confused when I talk about animation names.
