I HAVE A PONG GAME AND I NEED TO A.I CODE TO GET THE BAT TO MOVE THAT I AM NOT CONTROLLING SO THE COMPUTER PLAYS AGENST ME...
HERES THE CODE IM USING

[/code]rem SCORING
if ballx#>6 then player2score#=player2score#+1:ballx#=0:ballz#=0:balla#=270
if ballx#<-6 then player1score#=player1score#+1:ballx#=0:ballz#=0:balla#=90
set cursor 300,50:print player2score#
set cursor 320,50:print "-"
set cursor 340,50:print player1score#
rem BALL MOVEMENT
ballx#=newxvalue(ballx#,balla#,0.3):ballz#=newzvalue(ballz#,balla#,0.3)
rem PLAYER 1 PADDLE MOVEMENT
IF upkey()=1 and player1pos#<3.5 then player1pos#=player1pos#+0.5
IF downkey()=1 and player1pos#>-3.5 then player1pos#=player1pos#-0.5
if upkey()=1 and ballx#>4 and ballx#<4.5 then balla#=balla#+8
if downkey()=1 and ballx#>4 and ballx#<4.5 then balla#=balla#-8
rem PLAYER 2 PADDLE MOVEMENT
IF keystate(17)=1 and player2pos#<3.5 then player2pos#=player2pos#+0.5
IF keystate(31)=1 and player2pos#>-3.5 then player2pos#=player2pos#-0.5
if keystate(17)=1 and ballx#<-4 and ballx#>-4.5 then balla#=balla#+8
if keystate(31)=1 and ballx#<-4 and ballx#>-4.5 then balla#=balla#-8
rem BOUNCING
if ballx#>4 and ballx#<4.5 and ABS(player1pos#-ballz#)<1.5 then balla#=360-balla#
if ballx#<-4 and ballx#>-4.5 and ABS(player2pos#-ballz#)<1.5 then balla#=360-balla#
if ballz#>4 or ballz#<-4 then balla#=180-balla#
rem MAKE SURE balla# IS LESS THAN 360 AND MORE THAN 0
balla#=wrapvalue(balla#)
rem POSITION OBJECTS
position object 1,5,0,player1pos#:position object 2,-5,0,player2pos#
position object 3,ballx#,0,ballz#:yrotate object 3,balla#
position camera 0,10,-10:point camera 0,0,0
sync
loop
[code]
HERE

you could just get the computer to track the ball position and occasionaly get it to miss by making it move slow eg:-(psuedocode)

if rnd(10)=0
speed=0.9
else
speed=1
endif

if ballvert>batvert
batvert=batvert+speed
endif

if ballvert<batvert
batvert=batvert-speed
endif

how it works...as long as the bat is at a different position to the ball then the program will adjust the bats position to get nearer to the balls height, so it will be at the same height as the ball when it gets there, to stop it being infallible (boring to play against) we create a random number from 0 to 10, and if it`s 0 (on average 1/11th of the time, then we make the bat move slower by 0.1, so if the bat has a long way to go then it will miss the ball since it will get there late, and if it`s a short distance it will be a close thing if it gets it or not since the total error will be smaller, hope that explains things.

Mentor.

ok im sorry to bug you but that makes no sence to me.... do you think you could use an example so i could visialize it?

Mentor has the right idea. What you need to do is have one of the player paddles track the ball, but use the speed variable to introduce some error into the tracking so it is not a perfect player.

You need to add some logic to your player 2 paddle control. Something like this...



DISCLAIMER: You may need to tweak the logic or the constant values to get the results you desire. The purpose of this code fragment is to show you how to organize that logic and what to test for.

Posting tip 1: You first post here was correct. Anyone can click on the source button and see your code is a seperate window. You second post was redundant and you had the code tags backwards.
( [ c o d e ] and [ / c o d e ] not [ / c o d e ] and [ c o d e ] )

Posting tip 2: The code tags are handy when you want to display formated text where spacing is important. It is good for ASCII art, tables, and other forms of text as well as source code fragments.
