This must be simple, but I just can’t figure it out. I have a fps style environment which the user can use the arrow keys to swing the main camera around to look at the ‘world’. I would like to use the same arrow keys to control the rotation of a mesh object, using the space bar to toggle between both control methods. I have tried a few approaches without success. This latest effort doesn’t work at all…any suggestions?

on=0

;main loop********************************************************************************************
While Not KeyHit(1)

If on=1

lights_movement

c_arm_movement

unlock_table

position_cameras

check_flag

Else

lights_movement

camera_pick

camera_movement

position_cameras

check_flag

End If

UpdateWorld
RenderWorld

Rect x,y-3,1,7
Rect x-3,y,7,1

Flip

Wend
;*****************************************************************************************************

Function check_flag()
If KeyDown(57)
on=1-on
EndIf
End Function

the other functions work perfectly, but introducing another loop layer seems to muck things up completely. any suggestions...please
thanks,Shawnus

ok i can't help but try placing your cod in

{code} {/code} change {} to []

so {code} hi {/code}

becomes

hi

First line:

Global on=0

You need to make 'on' global to access it from a function, otherwise it's another 'on' being used in the function :)

Thanks for the replies. Actually, in my original code 'on' was global- I just published a condensed version to show people the basic structure. I Still haven't figured it out...

i would use on = 1
and then do on = on*-1 but thats just a prefrence, it may actually be working... try doing what your doing but putting a FlushInput(or something) and then a delay(100) and see if it works

Change:

KeyDown(57) --> KeyHit(57)

Maybe?
