So I'm trying to get keyboard input from the user to move a character. It works in another program that I was using, and I copy pasted, but it isn't working in this one. It gives me Line 87, Column 38 1119: Access of possibly undefined property EVENT_FRAME through a reference with static type Class. I can't seem to figure out what the issue is.
This is the buttonClick function that is used to when I hit the start button.
public function buttonClick(ev:MouseEvent):void
{
createGameScreen();
this.mcLink.gotoAndPlay("Idle");
this.mcLink.x=50;
this.mcLink.y=200;
this.mcLink.scaleX=this.mcLink.scaleY=3;
this.stage.addEventListener(Event.EVENT_FRAME, this.enterFrameHandler, false, 0, true);
}
This is the event handler function for the keyboard input.
public function enterFrameHandler($e:Event):void
{
if (this.mcLink)
{
if (KeyboardManager.instance.isKeyDown(KeyCode.DOWN))
{
if (this.mcLink.y + this.mcLink.height > this.stage.stageHeight || this.mcLink.y - this.mcLink.height <= 0)
{
this.mcLink.y += -15;
mcLink.gotoAndPlay("Idle");
return;
}
this.mcLink.y += _nHeroMovementSpeed;
mcLink.gotoAndPlay("Down");
}
else if (KeyboardManager.instance.isKeyDown(KeyCode.UP))
{
if (this.mcLink.y + this.mcLink.height > this.stage.stageHeight || this.mcLink.y - this.mcLink.height <= 0)
{
this.mcLink.y += 15;
mcLink.gotoAndPlay("Idle");
return;
}
this.mcLink.y -= _nHeroMovementSpeed;
mcLink.gotoAndPlay("Up");
}
if (KeyboardManager.instance.isKeyDown(KeyCode.LEFT))
{
if (this.mcLink.x + this.mcLink.width > this.stage.stageWidth || this.mcLink.x - this.mcLink.width <= 0)
{
this.mcLink.x += 15;
mcLink.gotoAndPlay("Idle");
return;
}
this.mcLink.x -= _nHeroMovementSpeed;
mcLink.gotoAndPlay("Left");
}
else if (KeyboardManager.instance.isKeyDown(KeyCode.RIGHT))
{
if (this.mcLink.x + this.mcLink.width > this.stage.stageWidth || this.mcLink.x - this.mcLink.width <= 0)
{
this.mcLink.x += -15;
mcLink.gotoAndPlay("Idle");
return;
}
this.mcLink.x += _nHeroMovementSpeed;
mcLink.gotoAndPlay("Right");
}
}
}
Did you mean Event.ENTER_FRAME?
this.stage.addEventListener(Event.ENTER_FRAME, this.enterFrameHandler, false, 0, true);
// ^^^^^^^^^^^ EVENT_FRAME isn't a known Event.

Hi I don't understand why you are getting this error, but this can help you,
try the follow code instead of Point();
var checkPoints:Array=new Array({x:85,y:140},
{x:85,y:320},
{x:325,y:320},
{x:325,y:200},
{x:265,y:200},
{x:265,y:80},
{x:505,y:80},
{x:505,y:380},
{x:630,y:380}
);
Ok, so I have an object on the stage that moves on the "world" movieclip. I'm trying to make it so that when you're moving right. If the movieclip inside the moving movieclip("dude") called hitD collides with the walls in world, the dude stops moving forward.
Screen shots if it might help.
General stage dude object selected
http://prntscr.com/5bgjfq the world is everything but the ball
http://prntscr.com/5bgjuh
hitD
If anyone has any way they can modify these collision physics since my current code is sketchy as hell, all suggestions and ideas are welcome.

Thanks in advance for any help you can provide :)
For player physics, it's more clear approach to make a central ENTER_FRAME handler function that just for calculating the transformations to be applied to player.
You can still get information from out, but you just process the final output there. Else, it could be problematic, especially when things gets more complex and when you want to add some more feature.(e.g. Imagine in the future, you wanted to add fans on the ground that blows air up, and player have to rise when on them. There you have a lot to change, and probably with many problems.
For collision detection, this function will provide you this information: to which direction(s) the player can't go with variables 'UpColl', 'DownColl', 'Right Coll' and 'LeftColl'.
Then you can refer to this information from your main function that applies the transformation to your player. I'll give example to that also below.
function collEveryFrame(event:Event):void
{
// capture player positions
player_x = WORLD.player.x;
player_y = WORLD.player.y;
// the movie clip object where you store your solid objects. Remember, ALL MovieClip objets inside this MovieClip will taken as solid objects in your game, and regardless their shape, their boundingBox will be taken as collison. So they will all be square.
collContainer = WORLD.cW;
// your player's collision object
playerColl = WORLD.player;
// RIGHT SQUARE COLLISION DETECTION
for (var i:int; i < collContainer.numChildren; i++)
{
// Check if any collision object colliding with player
if (playerColl.hitTestObject(collContainer.getChildAt(i)))
{
// One collision detected. Check 'from which side' does the player colliding with the object;
if (collContainer.getChildAt(i).y > playerColl.y + playerColl.height - p1MoveSpeed)
{
playerColl.y = collContainer.getChildAt(i).y - playerColl.height;
DownColl = true;
}
else if (collContainer.getChildAt(i).y + collContainer.getChildAt(i).height < playerColl.y + p1MoveSpeed)
{
playerColl.y = collContainer.getChildAt(i).y + collContainer.getChildAt(i).height;
UpColl = true;
}
else if (collContainer.getChildAt(i).x + collContainer.getChildAt(i).width < playerColl.x + p1MoveSpeed)
{
playerColl.x = + collContainer.getChildAt(i).x + collContainer.getChildAt(i).width;
LeftColl = true;
}
else if (collContainer.getChildAt(i).x > playerColl.x + playerColl.width - p1MoveSpeed)
{
playerColl.x = + collContainer.getChildAt(i).x - playerColl.width;
RightColl = true;
}
}
}
// RIGHT SQUARE COLLISION DETECTION [End]
}
Transformation function;
function playerMovement(event:Event):void
{
// (apply this for all sides)
// if nothing keeps player from going right;
if (! RightColl)
{
// Apply everything currently pushing the player to right
if (keyIsDown(Keyboard.RIGHT))
{
movement_Right = 15;
}else{
movement_Right = 0;
}
// example fictional wind function returns wind speed
windSpeed = getWindSpeed();
player.x += movement_Right + windSpeed + etc + etc;
// say windSpeed is -5 (Wind is coming from right, so pushing the player to left)
// so if user pressing right arrow key, player will move to right 10px for every frame, else 5px to left, etc.
}
}
In this way, everything about physics will be easy to implement.
For example, when calculating the movement to down, add gravity and jump etc.

Well, near the bottom of your code you say: Bunch.parent.removeChild(Bunch);
But you also have: Banana_mc1.addEventListener(Event.ENTER_FRAME, moveDown); which invokes a function that keeps referring to Bunch.
You could test that by NOT removing Bunch. If that fixes the null var problem then you'll have to decide how to proceed. Do you want the game to continue or end after Bunch goes away?
Then there's also this:
hitAry[i].parent.removeChild(hitAry[i]);
trace(hitAry[i]);
You're trying to trace it right after you remove it! That mightmake hitAry[i] null!

if (cpuScore >= 1)
{
stage.removeEventListener(Event.ENTER_FRAME, loop);
scoreBoard_L.visible = true;
}
}
Mouse.hide();
mywelcome.text = "Good Luck, " + myName;
function checkVisibility () {
for (var scoreBoard_W:String in buttonsStates) {
if(visible == true)
{
scoreBoard_W.addEventListener(MouseEvent.CLICK, goto3);
function goto3(Event:MouseEvent)
{
gotoAndStop(1,"Menu");
}
}
}
}
The problem is in this line
scoreBoard_W.addEventListener(MouseEvent.CLICK, goto3);
As you using for (var scoreBoard_W:String in buttonsStates){...} inside definition of function function checkVisibility () {...} you declare local String-type variable which block your access to button with same name.
Changing
scoreBoard_W.addEventListener(MouseEvent.CLICK, goto3);
to
this.scoreBoard_W.addEventListener(MouseEvent.CLICK, goto3);
will do the trick.
I'm having a problem with my jump function for a platformer engine. I've moved all of the hit testing onto the individual platforms in the level, so I don't have to write things out for each individual one. The problem with this is that only the first movieclip added to the stage can be jumped on to. The others just make the player sink through the floor if up is held down (as they should- as he's not meant to be there there's nothing to stop him).
So the problem is that the check for the jump just isn't registering properly on the second block. Here's the code (sorry about the excessive MovieClip(parent) s)
var playerRef:MovieClip = MovieClip(parent).player;
stage.addEventListener(Event.ENTER_FRAME, hitUpdate);
function hitUpdate(e:Event):void {
if (playerRef.hitTestPoint(playerRef.x,this.y - (playerRef.height/2)) && playerRef.x + playerRef.width > this.x && playerRef.x < this.x + this.width && !MovieClip(parent).upDown) {
MovieClip(parent).downMomentum = 0;
playerRef.y = this.y - playerRef.height;
}
if (playerRef.hitTestPoint(playerRef.x,this.y + this.height) && playerRef.x + playerRef.width > this.x && playerRef.x < this.x + this.width) {
MovieClip(parent).downMomentum = 0;
playerRef.y = this.y + this.height + MovieClip(parent).gravity;
}
if (playerRef.hitTestPoint(this.x,playerRef.y) && playerRef.y + playerRef.height > this.y && playerRef.y < this.y + this.height) {
MovieClip(parent).speed = 0;
playerRef.x = this.x - playerRef.width;
}
if (playerRef.hitTestPoint(this.x + this.width,playerRef.y) && playerRef.y + playerRef.height > this.y && playerRef.y < this.y + this.height) {
MovieClip(parent).speed = 0;
playerRef.x = this.x + this.width;
}
if (playerRef.hitTestObject(this)) {
MovieClip(parent).groundTouch = true;
} else {
MovieClip(parent).groundTouch = false;
}
}
And the jump function runs like this:
stage.addEventListener(Event.ENTER_FRAME, updates);
function updates(e:Event):void{
player.y += downMomentum;
if(!groundTouch && downMomentum < downMomCap){
downMomentum += gravity;
}
if(downMomentum > downMomCap){
downMomentum = downMomCap;
}
if(upDown && !jumping && groundTouch){
jumping = true;
jumpTimer.reset();
jumpTimer.start();
}
}
jumpTimer.addEventListener(TimerEvent.TIMER, jumpTick);
function jumpTick(e:TimerEvent):void{
if(downMomentum*-1 < downMomCap){
downMomentum -= jumpProg * jumpIncrement;
}else{
downMomentum = downMomCap * -1;
}
jumpProg -= 1;
}
jumpTimer.addEventListener(TimerEvent.TIMER_COMPLETE, jumpDone);
function jumpDone(e:TimerEvent):void{
jumpTimer.stop();
jumping = false;
jumpProg = 5;
}
I just can't find a solution to this, though I suspect it's something to do with how it checks for the player touching the platform.
