There is a lot more code in this game so the actionscript has been spread over a number of pages to aid explanation and make it a little more obvious what each function is doing.

Game Logic

In this game the logic flow is:

1. Initialise common variables
2. Add a function to the introduction movieclip to reset/initialise the game.
3. Initialise/reset the game each time it is played
   • Reset the scoreboard
   • Attach and position the blowpipe from the library
   • Attach and position targets from the library
   • Add a function to each target to make it move
   • Add a function to each target to reset it when popped
4. Start game engine
   • hide the mouse
   • Add a function to the blowpipe to detect keypresses for movement and firing darts
5. Additional functions required:
   • shoot and move each dart
   • pop the balloon when hit by a dart
   • game over when all darts used

The Code

Write or copy/paste the following actionscript into Frame 1 of the Actions layer.

Initialise the Game

/*
initialise common variables
*/
var num_targets:Number = 3;
var num_darts:Number = 25;
var score:Number = 0;
var miss:Number = 0;
var tx:Number = 600;
var lvl:Number = 100;
// function get click from intro movieclip
intro.onRelease = function() {
	init();
};
/*
hide the intro movieclip 
initialise game variables
attach the dartgun and set time to fire
load the targets
start the game
*/
init = function () {
	intro._visible = false;
	num_targets = 3;
	num_darts = 25;
	score = 0;
	miss = 0;
	lvl = 100;
	scoreboard.darts.text = num_darts;
	scoreboard.score.text = score;
	scoreboard.miss.text = miss;
	_root.attachMovie("blowpipe", "dartgun", 999);
	dartgun._x = 267;
	dartgun._y = 351;
	dart_ttl = getTimer();
	loadTargets();
