Really need ur help

[Dr Warm]

when i tried ur fla i couldn't get the enemy to move at all, also u seem to be using a tile based engine with art based buildings (did u get these ideas from tonypa or similar). the problem with ur enemy is that he can't tell if he's going to hit something.
With art based there's not really anyway to do this easily, this is because u can't check in advanced if something is going to hitTest == true with something until it happens.
The way to do this is to have four surrounding invisible squares around ur mc, have them called top, left, right and down. Then u have to go
if(_root.ball.top.hitTest(wall._x, wall._y, true){//<-- sorry i can't remember how to do hitTest, because i don't use them
//need to make new direction
number = Math.ceiling(Math.random()*3);
if(number == 1){
//heads down
_root.ball._y += 5;
}
if(number == 2){
_root.ball._x -= 5;
}
if(number == 3){
_root.ball._x += 5;
}
}

do u get what i mean, and u'd have to do something like this for all four sides, it'll get kindof messy.

What i'd recommend is going back to tonypa's tutes and just use the tile-based method, that he's already made and just 'borrow' his.


BTW please put a better title for threads i had know idea what this was about, like 'help with AI for maze' or similar.
And also many ppl don't have MX2004 so either save it in MX format or submit ur problem code and u (should) get quicker responses

Ok,thank a lot.i try to use the tile-based method to do.if still can't,i will ask u ok?thanks..

Anyone got another method to solve my problem....must tell me ok.

[keller]

Anyone got another method to solve my problem....must tell me ok.
Sorry,i still can't understand the tile-based method,coz if i use tat method i wan change a lot of thing.Do u and ur have another method?

[Dr Warm]

yeah for the tile based method u will have to change a few of ur things, but once u've changed them, if u want to change other things, it's easier just change a 0 to a 1 in an array etc. that's why i prefer this method

i think if u want to make AI with art based u'll have to devise your own method, because i can't think of any source that i have that will help you. But to start off with u'll need to do what i said before, with the four invisible boxes around the enemy for the hitTests.

ok thanks.i ll try my best.but if u or ur got another idea must tell me ok.thank a lot.

i looked again at ur fla, but i don't really understand how it works, maybe there's a new function that i've not looked at thats in MX2004, but i don't understand it:drool:.

in ur _root.onEnterFrame function for the character, when u have:
if(Key.onDown(Key.RIGHT)){
CheckXY(something);
}
i can't seem to work out how the checkXY works! could u explain it to me, cos u could probably use this function for the enemy as well

em...1st i write a function call function CheckXY(x,y){},u can see in my fla file.After that,i write _root.onEnterFrame function,So we no need write
if(Key.onDown(Key.RIGHT)){
CheckXY(something);
}
in MC of red.
So if(Key.onDown(Key.RIGHT)){CheckXY(1,0)},the 1 is x-axis,and is positive value,so the object will go right when i press the right arrow key.Can u understand?And When CheckXY(0,1),that mean y-axis is positive.

[Dr Warm]

no i get that bit, i just don't get how it see's what's to the left and right up and down, does it have something to do with u creating the tiles at the start, or is that only for the letters?

[keller]

left,right,up and down is for control my hero...So all i explain to u is only for my hero not the letter,Can get it?The purpose i write the function and the _root EnterFrame function is want use the arrow key to control my hero,so it will move around the maze when i press the up,dwon,left and rigth arrow key.Can get it?

[Dr Warm]

No that's not what i mean, i'll take another look at ur fla and see for myself (it's been about a week or two can't quite remember)

ok....but my game will pass to my lecturer after 2week.em....u knw how to use xml?Coz i never learn tis before.

[Dr Warm]

i only know the very basic.. basics, i would post on a different part of this forum for stuff on xml, there are heaps of ppl that use it alot

[Dr Warm]

i tried to do a ai for u but it doesn't quite work i'm not sure why, maybe if u see what i did u'll be able to fix it (hope this is the right version!)

Thanx a lot...i try to modify,see can work?thanx...but if u hav good idea for me must tell me ok?or anyone knw how to solve my problem,please tell me.Thanx...

[keller]

em...i can let the enemy work nw.but still got a little bit problem which is my enemy juz only can move randomly outer part of the maze.Can u tell me why?

Below is the fla file.

[Dr Warm]

em...i can let the enemy work nw. ok, at least that bits sorted, i'll see if i can get him to move around better, though i've not had much practice with this!

[Dr Warm]

em...i can let the enemy work nw.but still got a little bit problem which is my enemy juz only can move randomly outer part of the maze.Can u tell me why? yeah he only moves around the outer edge of the maze, because he only changes direction when something is blocking his way, and obviously if he's just moving along nothing 's blocking his way so he won't change direction.

There's two solutions to this:
1st: More simpler, just put walls in the way and force him to go there, but i don't think u want that do u?

2nd: Try to get him to scan directions while he's moving, test if he can move there and then move there, if he wants to. I've tried (and failed) to get this working, but maybe u can see what i'm trying to do in the fla file, for some reason it doesn't work, i can't figure it out.......

It should work, maybe there's an error in my logic, but more likely it's in the code

BTW when u post back, don't press reply in the bottom right corner, press "post reply" that way it doesn't just post all the things that i've said again, it makes it hard to read

[keller]

i knw wat u doing,i try to modify a bit.Thanx a lot.anyone got new idea must tell me k?Thanx....

[keller]

i think ur idea is good,so i use it.thanx u very much...

[Dr Warm]

did u get it to work? if so can u tell me what i did wrong :P, just for peace of mind :D

also what did u want the XML for?

[keller]

i juz delete the code below "startDir = downArrray[changeDir]" each direction,because i think that is good enough.

the XML i want is for connect my flash game,so i can change the language in my game,ei the word "flash" become chinese word,japanese or france.Can u understand?

[Dr Warm]

oh yeah i read about that yesterday in samples for mx2004. have you looked at that one, seems simple enuf?

[keller]

i have look the file,but i dunno how to use it.u knw?i got one day only.Haiz...so sad.
