Up with Birds!

Product Information

for element This is a simple version of the Flappy Bird game for micro:bit. The objective is to direct a flying bird, which is moving continuously to the right, between sets of obstacles. If the player touches an obstacle, they lose. The purpose of this tutorial is to teach the basics of game sprites, arrays, and loops. Step 1: Add the Bird to the Game Small birds: Can be firmly held in one hand, positioning the hand over the bird so that its head is between your fore and middle fingers, letting the rest of your fingers naturally wrap around the wings. if (obstacle3.get(LedSpriteProperty.X) == bird.get(LedSpriteProperty.X) && obstacle3.get(LedSpriteProperty.Y) == bird.get(LedSpriteProperty.Y)) {

Fledglings should be left alone unless they are in immediate danger and can be moved to a sheltered spot nearby e.g. under a hedge. It should fly away in a couple of days when its wings are fully developed!

Access each obstacle using a This is where things will start to get interesting. We’re going to randomly generate obstacles. We’ll keep all obstacles inside the array. All obstacles will have a single hole for the bird to fly through. Make obstacles disappear after reaching leftmost corner. Iterate over all obstacles, delete the obstacle sprites where the X coordinate equals 0, and remove them from the obstacles array. let obstacles: game.LedSprite[] = [] Make a note of exactly where you found the injured bird. The end goal of catching and rehabilitating an animal should always be to return it to the wild, so it's important to make sure that it can be released in the right location.

If it does, don't try to catch it, but if it doesn’t try to or can’t fly away then you may try to help it. Birds will usually be more comfortable with their wings held against their bodies, feet supported. Think about the size of the bird before you attempt to handle it: Before continuing, make sure that obstacles are generated randomly and that the bird is moving up and down. let emptyObstacleY = 0 loop ( iterate over the obstacles array) and decrease the obstacle X coordinate by 1. First, create an array of obstacles which will hold all of the obstacle sprites. let obstacles: game.LedSprite[] = []

Before creating the code for the game actions, let’s first add some controls so that we can move around. We’ll control the bird by pressing the A button to go up or the B button to go down. let bird: game.LedSprite = null loop, iterate from 0 to 4. For every coordinate not equal to emptyObstacleY create and add obstacle sprites to the end of the obstacles array. let emptyObstacleY = 0 Vets aren't obliged to treat wildlife for free, and typically aren't trained in the care of wildlife, so it is a good idea to call around local practices before visiting, and find out if your vet has links with local wildlife rescue groups to make sure the animal is taken care of after being treated. Using Large birds: It is best to call an expert rescuer as larger birds are capable of inflicting some damage to anyone trying to handle them. If the bird has flown into a window: Let it rest in a dark space for a few hours. It is possible that it has internal injuries or is concussed, so during this time the bird will either recover or will die from its injuries. if (obstacle.get(LedSpriteProperty.X) == bird.get(LedSpriteProperty.X) && obstacle.get(LedSpriteProperty.Y) == bird.get(LedSpriteProperty.Y)) {
