[AS3] enemy spawn and main menu

[douwexxl]

hi readers.

i building a shooting game all in actionscript (nothing on stage)

( weapon in first person view and a crosshair that is controlled by the mouse.
the barrel of the weapon follows the mouse. i got a reload system with bullet display etc. so thats all good,

but i want my game to have some levels, i want a max of 10 enemys in level one, when u killed all the enemys i want a GRATTS screen and a time and score.

at the moment the enemy keep on coming i dont know how to make like 10 enemys spawn and if u dont kill them within the timelimit u are dead.

all my enemys are inside a array they are pushed on stage and there is a timer to controll them a little. so for a next level i can make them spawn faster.

==========
next question.

i made a nice movieclip for the main menu with option and startbuttons,

but i cant figure out how to get it working everything i try lets the game crash. i got the movieclip on stage but when i click the startgame button it crashes.

can anyone please help with my problems??

thanks in advance.

Post some code and I'll help I don't know what you're doing currently. But most likely you need to wrap the spawning code with an if statement like
if(spawn)
{
spawnthem;
}

yes im trying to do it with for loops but then the enemy will spawn in sets of 10 and they still keep on coming. i need to get 10 enemy on stage one by one and after the last enemy gets on stage the push function stops.

what code u need i will post it thank u verry much.

Spawning code probably but depending on the size of the game post it all (Or at least all the stuff that is used by the spawning code).

[douwexxl]

well i just started building the game so i its not that big yet. i cut all the code i try`d using to get the enemy spawn limited to 10.

this is the raw code i used for the crosshair / spawnTimer and enemysound effect in the document class, to get the them on stage.


package {

import flash.utils.Timer;
import flash.ui.Mouse;
import flash.media.Sound;
import flash.events.Event;
import flash.display.Stage;
import flash.display.MovieClip;
import flash.events.TimerEvent;


public class Engineshooter extends MovieClip {

//array`s\\..

public static var enemylist:Array=new Array() ;
//==================================

//spawn timer\\

private var enemy:Timer=new Timer(5000);
//===============================

private var _crosshair:Crosshair;

//enemy sound\\
private var EE:Sound = new EnemyEngine ();


public function Engineshooter() {

Mouse.hide();

_crosshair=new Crosshair(stage);
_crosshair.x=stage.stageWidth/2;
_crosshair.y=stage.stageHeight/2;
stage.addChild(_crosshair);


enemy.addEventListener(TimerEvent.TIMER,onstart);

enemy.start();

function onstart(e:Event):void {

var _enemy:Enemy=new Enemy(stage);
_enemy.addEventListener(Event.REMOVED_FROM_STAGE,r emoveenemy,false,0,true);
_enemy.addEventListener("killed",enemykilled,false,0,true);
enemylist.push(_enemy);
//EE.play();
stage.addChild(_enemy);

}

}
private function enemykilled(e:Event) {
trace("enemy killed");
//scoreHUD.updateKills(1);
//scoreHUD.updateScore(e.currentTarget.points);
}

private function removeenemy(e:Event) {
enemylist.splice(enemylist.indexOf(e.currentTarget ),1);

}
}
}


================================================== ===============

this works fine the crosshair is controlled by the mouse and i can shoot to kill the enemy.

the enemyclass dispatches the "killed" event that all works the way it should

but as u can see there is no spawnlimit in there. i try`d using a for loop and if/else statements but then the enemy spawns in pairs and keep on spawing.
i just want to get 10 enemys in the first level of the game with a display howmany enemy are left in the level to kill, then up to next level where 15 enemy will spawn etc, etc.

oh and the scorehud u see in there isnt finished yet so i commented it out for now, i got the graphics and im writing the class for it today.



i hope u can do something with this to help me out. thanks.

while(enemySpawned <= 10 && gamenotfinished)//Some variable controlling if the game has ended
{
var _enemy:Enemy=new Enemy(stage);
_enemy.addEventListener(Event.REMOVED_FROM_STAGE,r emoveenemy,false,0,true);
_enemy.addEventListener("killed",enemykilled,false ,0,true);
enemylist.push(_enemy);
//EE.play();
stage.addChild(_enemy);
enemySpawned++;
}
That should make sure there are no more then 10 enemies and they will not spawn if the game has ended.

oke thank u verry much but where do i put the while code cause it dont seem to work could u please write it were i should place the code??

thank u.

}
}
}

That is all the code with mine added in. When you want the round/game to end and the enemies to stop spawning set gameFinished = true; and then back to false when you want them to start spawning again.

oke thank u verry much for ur help, im building the game main menu screen now,

so now my document class is the menuclass and i added all the button clips to the stage.

the buttons are movieclips with buttons inside them and they are added with AS in the menuclass, so when i load the game u get the menuscreen with options play game etc and when u press the options button a new movieclip is loaded with the options in it.

so the options screen listens to the options button now im building all buttons for the optionsscreen and when u press a button in the options screen u get a new screen.

the way im doing it it takes allot of different movieclip and AS files who listen to eachother, do u think there is a better way of doing this or is this the (correct) way.

[UberMouse]

I'm not much help there since I didn't do the menu's in my game. But I do know that the way it is done is that there's a buttonHandler.as and a screenHandler.as which is a function that you call that creates the buttons/screens dynamically using the functions.

[douwexxl]

oke well, the way im building works fine ill try and find some stuff to read about this in the next few days.

i build an options screen movieclip and on the timelines of that clip, im build the buttons and the next or pref screen.

so when i click on a button in the optionsscreen u gotoAndStop to the next framelabel.

on a actions layer in the optionsscreen clip is the code for the mouseclick and what to do if u click the button.

i know there must be a better way but for now its the easyest way to do it for me.

i know some timeline action scripting but i wanted to take it a step further and build a game with only AS this will be my first game that doesnt have any graphics on the main stage until u load the game.

i hope i get my game to work on the startgame button. the rest of the buttons is easy just some movieclips to call and or delete from stage.

[douwexxl]

oh by the way what do u know about sound and music on off functions?? i build a button in the optionsscreen to adjust the music and sound FX in the game
