When the Clock1.Timer goes off, we want all of our gold coin ImageSprites to move to a new random location on the Canvas. We will use Clock1.Timer and the ImageSprite's MoveTo method to do this. We want the coins to move to random positions on the screen. To prevent the pirate from moving off the screen, we will also use PirateSprite.Bounce when an edge is reached. This means that the user can now control the direction of the pirate ship with their fingers by flinging on the screen. We want to reassign PirateSprite's current heading to the heading given to us from PirateSprite.Flung. You may notice that PirateSprite.Flung takes in 6 attributes: x, y, xvel, yvel, speed, and heading. To do this, we will use the PirateSprite.Flung event handler. To move the PirateSprite, we want the user to be able to "fling" the sprite in the direction that they choose. Upload the goldcoin image and set Picture property to goldcoin. Upload the pirateship image and set Picture property to pirateship. Set the properties of the components as described below: Component To reset the game so the player can play again
We use the Clock for its Timer method to move the coins The background that we will be putting our imagesprites on To create this interface, put the following components into the Designer by dragging them from the Component Palette into the Viewer. When you finish, it should look something like the snapshot below (more detailed instructions below the snapshot). Use the component designer to create the interface for GetTheGold.

This tutorial introduces the following skills, useful for future game development:įor this game, you will have two types of imagesprites: pirate and gold coin. Switch to the Blocks view and connect to a device or emulator. Name it GetTheGold, and also set the screen's Title to "GetTheGold". Getting StartedĬonnect to the App Inventor web site and start a new project. You'll program an application that has a pirate ship whose goal is to collect all the gold on the screen. By building the Get The Gold App you will get practice with setting visibility, using Clock components and Timers, and detecting collisions in App Inventor.
