Zelda Game HitTest help

[amps7]

Hi,im experimenting with making a zelda game (not tile-based) and am in need of a code for when the hero hits a wall. I know this has been asked so many times before but i just cant seem to get a suitable code.

[Templarian]

to make it simple you are doing it on when the key is pressed right?

if(Key.isDown(Key.LEFT)){
character._x -= 4
if(hittest){
character._y += 4.
}
}
something basic like that but not in psuedo.

[amps7]

Thanks Templarian, i'll need to try it out when i get home. In the meantime,could you please help me with another confusing problem? What is wrong with this code:


if (Key.isDown(Key.UP) && Key.isDown(Key.RIGHT)){
this.gotoAndStop(3);
}
}


It looks perfect to me but doesnt seem to work at all. :(

[TheCanadian]

One of the brackets was facing the wrong way, try this:


onClipEvent (enterFrame) {
if (Key.isDown(Key.UP) && Key.isDown(Key.RIGHT)) {
this.gotoAndStop(3);
}
}

[amps7]

Sorry that was a manual error when i was typing it! Its Fixed now.

[TheCanadian]

So does the code work for you now?

[amps7]

No it doesnt seem to be working,i've made up a .fla of main character. Could you (or anyone else) please examine it to see what's wrong?
Heres the .fla.

[amps7]

Anyone? I can't seem to work it out :puzzled:

[Insane Knux]

Ah, don't feel bummed out! I'll give a go at it! ;)
So what exactly is your problem? He moves fine for me!

[amps7]

Thanks,I need you to examine the code for him diagonally right.



if (Key.isDown(Key.UP) && Key.isDown(Key.RIGHT)) {
this.gotoAndStop(3);
}
}


I just need you to see whats wrong with it and why he dosent seem to carry out the actions.

[Insane Knux]

Aight, I'm on it.

WEWT! 170th post! :thumb:

//EDIT
Currently it works, just the animation doesnt. Easy fix, brb.

[Insane Knux]

Alright man... I couldn't get it working... but tomorrow I'll take another swing at it...

[Lord Rahl]

Hmm, this is odd. I'm working on it now and I'll let you know with what I come up with.

[Lord Rahl]

Well I have to admit. I can't figure it out. I have seen it before and it still annoys me. Anyways, I worked up something similar for you to look at that does work. I'm still working on it and may possibly figure it out. Untill then, check out the posted fla.

[Aggrix]

Do this instead:



if (Key.isDown(Key.DOWN)) {
this.gotoAndStop(2);
}
else if (Key.isDown(Key.UP)) {
this.gotoAndStop(3);
}
else if (Key.isDown(Key.LEFT)) {
this.gotoAndStop(4);
}
else if (Key.isDown(Key.RIGHT)) {
this.gotoAndStop(6);
}


The other way was first checking for the right key and if it was down it would play frame 6. Then right after that it would play frame 3 for the up key. This was causing it to keep switching from frame 6 to 3 and not play out the walking animation on frame 3.

Bravo Aggrix. ;) And to think it was so simple. Though, I should have noticed that right off.... or at least tried the same thing. :look:

[amps7]

Thanks Aggrix,Lord Rahl,InsaneKnux and The Canadian for your help.
It was very simple but things like that can really throw you off.

[amps7]

Ok,one more question (i think...). Is there a more effective way of doing a hittest for circular objects or more complicated objects?

[Lord Rahl]

You can do it multiple ways, but this script works with round objects better than most. Just place it in your goodguy MC and replace object with wall or whatever.


onClipEvent(enterFrame){
if (_root.object.hitTest(getBounds(_root).xMax, _y, true)) {
//place script to back track speed here
//example: _root.object._x -= _root.speed;
}
if (_root.floor.map.hitTest(getBounds(_root).xMin, _y, true)) {
//place script to back track speed here
}
if (_root.floor.map.hitTest(_x, getBounds(_root).yMax, true)) {
//place script to back track speed here
}
if (_root.floor.map.hitTest(_x, getBounds(_root).yMin, true)) {
//place script to back track speed here
}
}

Thanks,now this is what i've got so far:

The .fla is 104kb zipped so i've hosted that.

[Lord Rahl]

Its great so far. Is there a talk key or way of entering house yet?

Edit: Also, is the fairy part of the main character MC? If it is, your main character will stop when it hits the wall too.

[Insane Knux]

Heh, very nice game.
Oh, and bravo Aggrix! You obviously pay more attention to detail!
Also: YAY! I was thanked :) lol.

[TheCanadian]

Talk with space.

[amps7]

Thanx guys.

Lord Rahl, i haven't added the ability to enter the house yet. Talk is with Space (as the canadian mentioned). The fairy isnt part of the main characters MC and it has just got a simple co-ordinate code on it for staying slightly behind the hero.

[amps7]

Sorry for asking another question but i'm learning ALOT here. What would be the most effective way of playing an animation when the hero hits a wall or a tree. If you know Zelda games then you will know that whenever link moves into a wall that he cannot get by he plays his "pushing" animation.

[TheCanadian]

Put this on Link.


onClipEvent (enterFrame) {
if (this.hitTest(_root.tree)) {
gotoAndPlay("treeHitAnimation");
}
}

"treeHitAnimation" is the lable of the frame you would like to play.

[amps7]

ok,thanx

[amps7]

Ok,ive been experimenting tryin to achieve a Zelda style scrolling and its harder than i thought. So far ive got a code on the Hero's MC that states when the hero reaches a certain X or Y value (the end of the screen) the view switches to a different frame.This works ok except for the respawning nd positioning of the Hero on the different frames. Can anyone help me out?

[nathan99]

ok, i dont like your hitTest too much. :) you should use a if not hitting when button is pessed then move for eg


if(Key.isDown(Key.LEFT)){
_xscale=-100;
if(!_root.leftwalls(this)){
//if the left walls are NOT hitting
_x-=speed;
//move left
}
}


get me? this way seems a lot smoother, heres how i have used it in a game im doing now

[nathan99]

add i_eat_lots_of_food@hotmail.com to ur msn if u have it and i can help

[amps7]

ok,thanx

are you creating your graphics in photoshop, imageready, illustrator?? i want to do something like this, but i want to create my own characters, i just wanted to know what program works the easiest, i was thinking of making a character pixel-like just like link.

- Thanks

[smack_boom]

Hey amps! If you want to take this game furthur maybe i can help. I've made an Zelda engine in the past.

[nathan99]

ok i have accepted

[amps7]

jonathanOber- The graphics used are just sprites ripped from the original SNES game.
SmackBoom- Any help i get is appreciated!
