[Resolved] [Resolved] [Resolved] [Resolved] tank A I ?

ummm ok i think i figured how to make the auto aim thingy
i still need help for the chopper though
anybody? anybody at all???

its probably something silly that i can see
cia:D

i would also like some suggestions on how to make a good hittest for this kind game
tommason sent me something but i still dont know how to apply that to a mc though




http://digilander.iol.it/magneto1/tank1.swf

this is a circular tracking MC.
all the code is in the chopper MC.
note that the chopper MC is only a container for the shape MC which should be your actual chopper.
it circles the tank by;
1. moving the center for the chopper MC to same x/y as the tank MC
2. adjusts the x/y of the shape MC so it remains in the same physical position
3 then it simply rotates the chopper MC

hope this helps
BlinkOk

thanks blink you r on the bowl as usual :D
but the chopper is not facing the tank it just spins around it and also moves exactly when i move the tank making it look kind of weird

what i am trying to accomplish is this

the chopper follow the tank (as is doing with tommason code is fine)

now when the tank stops the chopper eventually catch up with it
and once the chopper is to close (not on top of it)starts spinning around the tank
later i gonna make the chopper shoot
now when i move away the chopper follow me but with a slight delay making look like i am actually outrunning the choper

anyway i will try to tweek your code to accomplish this
although i doubt it as i said before my math skill really sucks :D

cia:D
thanks again blink

magnetos have a look at this:
http://geocities.com/ugur112/flafiles.html
I made a sample for you there.
Tell me if it is what you need or what to change

waooo tom thats cool but it was so slow i got scare:D

yeah thats ok but (yeap there is always a but damn it:D)

the following is cool and also the spinning is cool

but when the chopper start spinning and i move the tank
the chopper immediately moves too
i mean the "following" becomes totaly dependent on the tank movement key press
that doesnt feel right does it?


there should be some sort of random delay that will make the chopper follow the tank after the tank moves

thanks tom

cia:D

hey there magnetos,i noticed your post and wanted to answer quick as it seems like it´s the first time in some days that we´re in at the same time :)
i know,the speed is jerky but that´s mainly because of the second swf posted on the page (which is much more cpu consuming).
I´ll make seperate pages for each flash example but i´m a bit lazy with that until i get my hands on mx...(made this page extra for you).
Download the file and run it as it is and you´ll see it´s much faster.I know what you mean with the delay following,i´m adding it right now and will update the file on the page within the next hour.
hope that helps
ha,it was a good idea to post the first part of my post before writing on,so i could catch you while you were in :)
No it´s some hours before i´ll go to bed,it´s 22.52 (or 10.22.pm) here,by the way,i´m not from the netherlands but from germany,but the time ´difference is almost the same (i think).

waoooo tom cant you sleep?:D

by the way: I´m pretty good in creating pathfinding ai (and npc movement in general) for tilemapped games but i skipped working on them as it looks like (the current) flash is too slow to handle bigger tilemapped world with scrolling.So i started making it not tilemapped,what´s much faster and allows me big maps with scrolling but makes up some new problems (like tileheight and pathfinding).Especially pathfinding seems much more complicated in non-tilemapped worlds,as i have to create ai for the npcs so they can decide which mcs are walkable and how to find the shortest path.
Please have a look at my current approach and tell me your ideas about it:
http://www.geocities.com/ugur112/pat...iourtest1.html
the character is placed at a random position on the start area and finds his way to the goal

thats pretty cool tom do you use hitTest to spot the walls?

the npc i have is from one of those mad-sci tutorials
and it uses hitTest to detect the walls
he used more or less this alghoritym

if( wall detect_wall= true)
{stop to think a random small time}
if (think is over){change direction }
else{ keep going}

it also checks if the npc is close to the hero/tank and if so it stops

i am gonna make it so that when he stops he rotates facing the hero/tank and start shooting

c:D

yes,the version on the page still used hittest,but in the newer version i´m working on right now i use the collision system from our collisionok2.fla (the one i sent you of which the swf is left to the tank sample page).
It doesn´t use hittest and runs much better (faster) because of that.
In that one all mcs on screen are sorted in an array and hittest is made based on their coordinates
(pythagoras+proto stuff.
I´m pretty much finished with the delay thing,give me twenty minutes and it´s there ;)

thanks tom... look forward to it

sorry for the dely (;) ),magnetos,but i wanted to put all in the code of the chopper and keep it simple.
i think this is what you wanted.
http://www.geocities.com/ugur112/flafiles.html
(click on "chopper with delay version")
the heli has a random delay (between 9 and 14 seconds) when it reaches the tank before it can move again.
I think it will look quite cool when you add a "hoover left-to right and other way round" animation for that time.
If you need something else,feel free to ask

Thanks tom that look great !!
i go play with it now:D


ps why do you still use

setProperty (this, _x, getProperty(this, _x)-movex);
setProperty (this, _y, getProperty(this, _y)-movey);

don t you like the flash5 dot notation?
i know i know is just i started with flash5
and i have trouble understanding flash4 syntax

well thats it for now
cia:D

glad you liked it.Tell me when you want help/suggestions or show the new version :)
well for the scripts,i just use what i´m used to,so there are also some flash4 thingies in it sometimes (i replace them when looking at the code again,but while coding it,i just write it (and somehow i remember those things from flash4 best which were most difficult to accomplish then...)
I´ll change that with the next version (if you have a new request and i work on it again),but since i downloaded flash mx i´m changing and enhancing all my flas with it,that´s real fun.

I don't have access to an Algebra or Trig book at the moment, and I'm in need of some AI help for my 2D space game. Should I continue my posts here in magneto's post or should I really open a new post, going over the situation there?

Thanks,
TotalMonkey

well,magnetos has to decide,it´s not my thread,just tel your problem/what you want to achieve (here or in a new thread),we´ll see what to do about it then :)

whatever you want totalmonkey ....its cool with me
cia:D

Cool. thanks, magnetos, but I've decided to open a new thread since mine really goes into more than just AI at the moment. Since the subject reads "tank a.i.", it's more fitting that the thread should be about tank a.i. :D

Thanks, again, and here's the thread I've started about my problems:
http://board.flashkit.com/board/show...hreadid=281665

Folks here, please take a look, as there'll be more problems to fix after I solve the first one (a coordinate system issue, i think). Thanks! :)

TotalMonkey!

how do you stop the tank when it touches a building?
and when i make the damageground thing... how do u keep it on the bottom cuz when it duplicates the thing, it makes it on top of everything and how do u keep the size and rotation different everytime?

thanks, moogle

hello?
