AS: Basic Movement

[Denvish]

Basic Movement

Left, right, down, up, and diagonal movement

On the main stage, select the MC you wish to make move
Add Actions:

onClipEvent(load){
speed=10; stop();
}
onClipEvent (enterFrame) {
_x+=Key.isDown(Key.RIGHT)*speed;
_x-=Key.isDown(Key.LEFT)*speed;
_y+=Key.isDown(Key.DOWN)*speed;
_y-=Key.isDown(Key.UP)*speed;
}

Unfortunately, this one doesn't allow for changing the orientation (eg walking)... so

Left, right, down, up movement with orientation

Create a new MC with 4 frames.
On the first frame, add your character walking right.
On the second frame, add your character walking down.
Third frame, left. Fourth frame, up.

Put the MC on the stage and add these actions:
onClipEvent(load){
speed=10; stop();
}
onClipEvent (enterFrame) {
if (Key.isDown(Key.RIGHT)){_x+=speed; gotoAndStop(1);}
if (Key.isDown(Key.DOWN)){_y+=speed; gotoAndStop(2);}
if (Key.isDown(Key.LEFT)){_x-=speed; gotoAndStop(3);}
if (Key.isDown(Key.UP)){_y-=speed; gotoAndStop(1);}
}

---------------------------------

If you wish to use the WASD keys, the keycodes are:

WASD -- ARROWS -- A.KEYS
- (68) ------ (39) ------ (Key.RIGHT)
- (65) ------ (37) ------ (Key.LEFT)
- (87) ------ (38) ------ (Key.UP)
- (83) ------ (40) ------ (Key.DOWN)

Use them like this:
_x+=Key.isDown(39)
or
if (Key.isDown(39)){_x+=speed;}

Other useful ones:

SPACE -------- (32)
ALT ------------ (18)
ENTER -------- (13)
BACKSPACE --- (8)
SHIFT --------- (16)
Z --------------- (90)
X --------------- (88)
C -------------- (67)

Sweet job man, I learned a few things myself.

I hope this and your many other text tutorials help all in need.

Basic side-scroller (walking) movement

The variable 'dir' just holds the direction in which the character is moving, so he knows which direction to face when stopped

onClipEvent(load){
speed=10; stop(); dir=0;
}
onClipEvent (enterFrame) {
if (Key.isDown(Key.RIGHT)){
_x+=speed; gotoAndStop(2); dir=0;
}else if (Key.isDown(Key.LEFT)){
_x-=speed; gotoAndStop(3); dir=1;
}else{
if (dir==0){
gotoAndStop(1);
}else{
gotoAndStop(4);
}
}
}

That snippet assumes that frame 1 is stationary facing right, frame 2 is moving right, frame 3 is moving left, frame 4 is stationary facing left. Don't ask why they're in that order... ;)

for(i=0;i<numPlats;i++){
if(this.hitTest(_root["plat"+i])){
this.jump = false;
}
}

This is a really basic multi-object hitTester. What it does is it goes through and checks to see if the hero is hitting plat0, plat1, plat2, etc. and stops the character's jump if he is touching the platform. All you have to do is put this on the hero mc's enterFrame handler, then rename ALL the platforms according to this pattern: plat0, plat1, plat2, plat3, plat4, plat5... Then, on the hero, create a numPlats variable and set it equal to the number of platforms on the stage.

Sorry guys, I n00bulated. The above code is an addition to the Side-Scroller tutorialette that Denvish wrote (2 posts up).

Heh. Thanks for the input me ol' china. I'm probably going to a jumping/gravity thread at some point, your snippet will probably suit that or the hitTest one better. But it's all good.

[gamatek]

see now the thing is that if I put make it so the character attacks when the user clicks D it wont work, here is the code I put for the attack,Key Up being the attack key, but its not working

onClipEvent (enterFrame) {
if (Key.isDown(Key.UP)) {
_x += speed;
gotoAndStop(5);
}
if (Key.isDown(Key.RIGHT)) {
_x += speed;
gotoAndStop(2);
dir = 0;
} else if (Key.isDown(Key.LEFT)) {
_x -= speed;
gotoAndStop(3);
dir = 1;
} else {
if (dir == 0) {
gotoAndStop(1);
} else {
gotoAndStop(4);
}
}
}

any help

How do i make checkboard movement? like in the game frogger? so that rather than him moving smoothly he takes big movements at a time, but not right away, so even when holding down the arrow key, he doesnt keep moving super fast, it takes like a second between eahc move?

I don't know n and b by heart, but i know e is 69. Or is it 65? One of those, for sure.
