问题 Below is what I have so far. At the moment, the player moves, and all I want it to do now is face the mouse cursor at all times (think Hotline Miami or other top-down games). I've used some code involving atan2 that I found online, but I barely understand what it does (finds the distance between the player and mouse somehow...) and my character just spins wildly offscreen until I get an 'Out of memory' error. Any help would be much appreciated, I've looked all over the internet and can't find

问题 This question already has answers here : Pygame doesn't let me use float for rect.move, but I need it (2 answers) How to draw a moving circle in Pygame with a small angle at a low speed and blinking? (1 answer) Closed 13 days ago . My code is acting differently for negative velocities than it is positive ones I'm trying to implement platformer physics, the player has velocity in the X direction, the velocity is increased or decreased when the user presses "A" or "D" respectively, or set to 0

Basically, in the original, the wall sliding works very well on the inside of the walls, but I wanted to make it work on the outside as well, so I made a new basic

问题 I have a problem with a game that I'm doing. I basically have objects that are in a map and I have to check for each of them if they collide with the walls (and then do something). Since was working with AS2, I thought about doing the same way: I drew a picture with only the walls, so with only rectangles and everything else in between is transparent (does not exist, then the floor for example). In AS2 I put the image to the screen, let's call it wall, and then I did a hitTest to wall with
