Implementing a simple character using classes.
The example below shows how to implement a simple top down character using classes. I think it is pretty easy to understand and someone might be able to use it to step into object oriented programming (oop). I hope this is helpful. Cheers!
// This creates the class and tells the class what properties to use when created. In your main file's init() method use the 'new' // keyword to create a class. This would look like 'myNewPlayer = new Player(0, 0, 2, "player", 32, 32). The values are going to depend // on your game. The image parameter is the name of your sprite you made in the sprite editor. Player = class constructor = function(x, y, speed, image, width, height) this.x = x this.y = y this.speed = speed this.image = image this.width = width this.height = height end // Call this in your main file's update() method example: player.move() move = function() if keyboard.UP then this.y += this.speed end if keyboard.DOWN then this.y -= this.speed end if keyboard.RIGHT then this.x += this.speed end if keyboard.LEFT then this.x -= this.speed end // Comes from the 'helper' source file's Clamp Function. This file is linked from the main tutorial page. this.x = clamp(this.x, -screen.width/2 + this.width/2, screen.width/2 - this.width/2) this.y = clamp(this.y, -screen.height/2 + this.height/2, screen.height/2 - this.height/2) end // Put a call to this in your main file's draw() method such as 'player.draw()' draw = function() screen.drawSprite(this.image, this.x, this.y, this.width, this.height) end end
