well he has awful organization (at least i think so)
i made it all on separate lines and you get

+ Code Snippet

do
if rightkey()=1 then Dxpos=Dxpos+10

texture object 1,1

if Dxpos>2500 then Dxpos=-2500
if leftkey()=1 then Dxpos=Dxpos-10

texture object 1,5

if Dxpos<-2500 then Dxpos=2500  
if inkey$()=d then wxpos=wxpos+10

texture object 3,3

if wxpos>2500 then wxpos=-2500
if inkey$()=a then wxpos=wxpos-10

texture object 3,6

if wxpos<-2500 then wxpos=2500 

position object 1,Dxpos,Dypos,0
position object 3,wxpos,wypos,0

sync
loop

why not try this

+ Code Snippet

do

texture object 1,5
texture object 1,1
texture object 3,3
texture object 3,6

if rightkey()=1 then Dxpos=Dxpos+10
if leftkey()=1 then Dxpos=Dxpos-10
if inkey$()=d then wxpos=wxpos+10
if inkey$()=a then wxpos=wxpos-10

if Dxpos>2500 then Dxpos=-2500
if Dxpos<-2500 then Dxpos=2500  
if wxpos>2500 then wxpos=-2500
if wxpos<-2500 then wxpos=2500 

position object 1,Dxpos,Dypos,0
position object 3,wxpos,wypos,0

sync
loop

why is everything so random in you other code? i just put all the textures together and all the ifs together.
just so you know, if you put a :, its just like pressing enter, it counts everything after the : as the next line. i dont know if what i did will change anything

that would change the whole way the code works .... youd have to go:

+ Code Snippet

if rightkey()=1
  Dxpos=Dxpos+10
  texture object 1,1
    if Dxpos>2500
       Dxpos=-2500
    endif
endif

as opposed to what you guys are saying...cause its a nested if statment not 2 seperate ones...unless im missing something, but u guys should be more carful cause its completely different code

no, its not nested, if you want it to be nested the you would have to have:

+ Code Snippet

do
if rightkey()=1 : Dxpos=Dxpos+10 : texture object 1,1 : if Dxpos>2500 then Dxpos=-2500 : endif
if leftkey()=1 : Dxpos=Dxpos-10 : texture object 1,5 : if Dxpos<-2500 then Dxpos=2500 : endif
if inkey$()=d : wxpos=wxpos+10 : texture object 3,3 : if wxpos>2500 then wxpos=-2500 : endif
if inkey$()=a : wxpos=wxpos-10 : texture object 3,6 : if wxpos<-2500 then wxpos=2500 : endif
position object 1,Dxpos,Dypos,0
position object 3,wxpos,wypos,0
sync
loop

if the code has the word then, then it isnt a nested if/then.

oh, i think iv got it

+ Code Snippet

do
if rightkey()=1 then Dxpos=Dxpos+10 : texture object 1,1 : if Dxpos>2500 then Dxpos=-2500
if leftkey()=1 then Dxpos=Dxpos-10 : texture object 1,5 : if Dxpos<-2500 then Dxpos=2500  
if inkey$()= "d" then wxpos=wxpos+10 : texture object 3,3 : if wxpos>2500 then wxpos=-2500
if inkey$()= "a" then wxpos=wxpos-10 : texture object 3,6 : if wxpos<-2500 then wxpos=2500 
position object 1,Dxpos,Dypos,0
position object 3,wxpos,wypos,0
sync
loop

when you see a $, it means that it is a string, and what ever a string is equal to, must have "" around it, see in my code above
