Would somebody please explain how to move object with the letter keys on the keyboard. I've used the arrow keys for moving my editting camera and would like to keep it this way for now, it helps me see quickly where i place my objects on the matrix.

anyways, I'ved looked at variuos codes for ideas and just can't seem to pull it off. help would be appriciated
thanx

You can use the scancodes for that. For instance, like the following snippet...

+ Code Snippet

#constant A_KEY = 30
#constant B_KEY = 48

key=scancode()
select key
  case A_KEY
    nove object playerobject,2
  endcase
  case B_KEY
    rem do something else
  endcase
endselect

Could you post the code snippet where you use the arrow keys for moving, so we could help you better... ? ...and no, not the whole source, just the part where the moving stuff occurs.

rem move edit camera
repeat
rotate camera camera angle x(0)+(mousemovey()/2.0),camera angle y(0)+(mousemovex()/2.0),0
cx#=camera angle x(0) :cy#=camera angle y(0)
if upkey()=1 then xrotate camera 0,0 : move camera 0,0.2 : xrotate camera 0,cx#
if downkey()=1 then xrotate camera 0,0 : move camera 0,-0.2 : xrotate camera 0,cx#
if leftkey()=1 then yrotate camera 0,cy#-90 : move camera 0.2 : yrotate camera 0,cy#
if rightkey()=1 then yrotate camera 0,cy#90 : move camera 0.2 : yrotate camera 0,cy#
if wrapvalue(camera angle x(0))>40 and wrapvalue(camera angle x(0))<180 then xrotate camera 0,40
if wrapvalue(camera angle x(0))>180 and wrapvalue(camera angle x(0))<280 then xrotate camera 0,280

this i used from them manual from controlling the player but put it on my edit camera from the get go so i could see where i was placing objects

this is my first program what im trying to do is create a vehicle combat game in pro. I felt that with it having a simple arena with very little animation it would be a good place to start. I've read the book 600+ pages but all the exaples are classic with the example game having lots of sever crap that at this point i don't care to deal with.

what object number is your vehicle? just use
if keystate(17)=1 then move object <vehicle number here>,10
put that in your main loop

Ok here you go this is a working bit of code.

+ Code Snippet


autocam off
sync on

`make object to move around
make object cube 1,10
position object 1,20,5,20


`make a matrix so you can see object moving
make matrix 1,5000,5000,50,50



do

`get keyboard input 30=a key, 44=z key, 24=o key, 25=p key
if scancode()=30 then move object 1,2
if scancode()=44 then move object 1,-2
if scancode()=24 then dec angle#,2
if scancode()=25 then inc angle#,2

`get object position to use with set camera to follow command
x#=object position x(1)
y#=object position y(1)
z#=object position z(1)

`rotate object to new angle
yrotate object 1,wrapvalue(angle#)

`positons camera
set camera to follow x#,y#,z#,angle#,35,10,10,0

sync
loop

Just copy this you should be able to figure out how to include it in your own program.
