![]() This code s hows the snake’s properties: //. To store information about the snake’s direction, add a property called snakeDirection of the type PVector. To store the positions of the snake’s rectangles, add a property called snakePositions of the type ArrayList. The snake will also require a property specifying the direction of the snake. The snake will require a property specifying the position of each rectangle representing the snake’s tail and head. When the general properties are in place, it’s time to add the properties for the snake. We use the boolean variable gameover to check if the player has lost the game and the float variable s specifies the size of the rectangles representing the objective and the snake.ĭisplay the first two properties of the game: // A boolean used to check if the game is ended The first two properties to add are gameover and s (see code below). The first step is to add global properties that can store information about size, positions, etc. More For Game Developers How to Built A Career in the Gaming Industry ArrayList refers to a list of other data types that can be dynamically resized and PVector refers to a two or three-dimensional vector. Boolean and float are primitive data types boolean refers to a value that can be either true or false, and float refers to a number that, unlike an integer, can specify a whole number and a decimal part.ĪrrayList and PVector are composite data types. Here is a short overview of the data types used to add properties to the game. To keep the article simple, the following section is divided into different steps of coding the game.
