These commands take care of moving the Player around: The user presses the arrow keys to move the Player. The Player will not move automatically, because there is no. pl.ace command puts the Player at location (400,450). setSides command says that the Player will STOP at the edges of the movement box, which extends from 0 to 800 across and from 200 to 600 up and down. The new Sprite command load 16 images named : grinch0001.jpg, grinch0002.jpg. In setup, the Player Sprite is created by thise commands: These are displayed one after another, creating an animation. The Player is considerably more complex than the Cookie.
PROCESSING MAKE SCREEN WRAP AROUND CODE
We don't need a movement command like : cy = cy + 20, because the Sprite code takes care of moving the Sprite - that's automatic. That command does 2 things - draws the Cookie AND moves it. In the draw method, the Cookie only needs one single command: The image isloaded, the cookie's starting position is set to (200,0), it's speed will be 0 across and 20 down, and it will wrap around when it reaches the bottom of the screen. In setup, the Cookie Sprite is created by these commands:Ĭookie = new Sprite("cookie.jpg") // load the imageĬace(200,0) // starting positionĬtSpeed(0,20) // speed of movementĬtSides(2) // side behavior = wrap around It is a single image - Cookie.jpg - stored in the sketch folder.
It won't run by itself, because you also need the Sprite class (available in the. Here is the code for the CookieMonster program. The user presses the arrow keys to move the Player around, to get it under the falling cookie and "eat" it. This program has 2 Sprites - the Cookie and the Player. we can hide all the complexity in the package, so our program only contains the control commands that we want to write someone else can do all the really tricky coding methods that can do things like moving the Sprite, changing directions, hiding, etc.īy using a Sprite class, we gain several advantages : variables with data about the position and speed of the Sprite That approach leads to complex, messy programs with lots of variables and lots of commands.Ī sprite is a moving character in a video game. We have made some simple video games using the normal drawing commands available in Processing.
