ExitLocation - output, results, fanfare-ovation.

StartLocation - here the menu and invitation to the game is spinning.

Supporters of MVC models are already crying, because and logic and representation are stuck in the body of the class. We will try to develop the application architecture in the best OOP traditions. Pygame is not an exception, so I suggest not to dwell on the details of the implementation of this library, but it should be noted that its tools allow you to load an image, and simply move it along x and y. She is, she is understandable, she is not without excellent examples. Python is great in terms of documentation.

I am not a professional programmer and this is not my main activity.

Yes, most likely nonsense - use an interpreted language to write games.

Yes, the idea is not new, but it turned out cool.

The character can now only jump, but I plan to finish the game to the end.

Yes, I used other people's pictures - I am ashamed and I will fix it soon.

For example, the Doodle Jump game was implemented (partially). That may be desirable for some games, but it isn't how jumping works in the real world.I want to tell and show you my experience of acquaintance with the pygame library - presumably an excellent library for the implementation of graphical applications (mostly arcade games) in the python language. The velocity squared physics rises quickly initially and hovers at the top of the arc longer.

Then I changed self.m = 8 to make jump height about same as original.Ĭhanging the code that handles the jump physics results in a nice parabolic jump as in real world physics. To keep changes to a minimum, I replaced the "if self.v>0" expression for F with one line: Mass doesn't play into vertical velocity (ignoring air drag) as all objects are accelerated by gravity at the same rate. If you change (self.v*self.v) to (self.v) you don't need the if/else because the expression proportional to self.v changes sign with self.v. But the F term should be proportional to v not v^2. The vertical velocity, v, does decrease linearly due to constant acceleration (because v = at) as your example program does. The change in y-coordinate is given by dy = v * dt, where dt is the constant time step. But what you really want to do is calculate the change in the vertical y-coordinate for constant gravity acceleration while jumping. The expression 1/2 * m * v^2 is kinetic energy not force. Very helpful tutorial for understanding pygame programming.

If you want to jump on objects, simply add them to the screen, do collision detection and reset the jump variables if collision is true. Self._display_surf.blit(self._image_surf,(,)) Self._image_surf = ( "pygame.png").convert() Self._display_surf = _mode((self.windowWidth,self.windowHeight), pygame.HWSURFACE) If the player is, its position will be updated according to the above formula. In Python, we set a variable isjump to indicate if the player is jumping or not. If the player reaches the ground, the jump ends. The velocity goes down over time because when the player jumps the velocity will not increase more in this simulation. Where F is the force up/down, m is the mass of your object and v is the velocity. For jumping, we use a formula from classical mechanics: F = 1/ 2 * m * v^ 2 Moving left and right is similar to the previous tutorial and simply mean changing the (x,y) position of the player. To do so, we will implement the player logic.
