Hello! I am having a very annoying problem with compiling my program. I keep getting: Variable 'MOUSECLlCK' does not exist in program.

I ran a demo program for MOUSECLICK() and it worked well but when I copy the lines into my program I keep getting the above mentioned error. I delete and re-type the lines in case there were any hidden characters or glitches. This is a snippet where it halts:

rem ::::: Move routine with Mouse plus some cleanup
REM *** Check for mouse click ***
mousevalue = MOUSECLICK()
if mousevalue=1
move camera 32
dce$= " "
die3$= " "
line1$=" "
line2$=" "
line3$=" "
line4$=" "
line5$=" "
line6$=" "
line7$=" "
line8$=" "
endif

if mousevalue=2 then move camera 32*(-1)
ry#=wrapvalue(ry#+mousemovex())
rotate camera rx#,ry#,0

Any help or suggestions. The mouse clicks moved the camera in a 3-D environment forward or backwards.

It runs fine for me. Is this copy-pasted from your actual program? If not, check your spelling or post your actual code here, following the example:

I found the source of my problem. Had nothing to do with MOUSECLICK() but the compiler.

In the past I was able to do this with my coding:

else:endif

and Mouseclick():Rem select Left or right click

For some reason now, the new compiler does not see ":" as a divider. I re-wrote and removed all the ":" dividers and I no longer get the 'Variable' error no more on Mouseclick(). Any ideas? I have what came with Dark Game Studio and latest update to DPPro.

Sorry for the double post. Newbie you know.

You still can use : as a divider but it requires a space and I would not recmend it for comments. Just use one of the following:

+ Code Snippet

// I'm a comment
` I'm a comment
' I'm a comment
rem I'm a comment

remstart
   I'm a comment block
   I can go on until the rem+end is called
   Useful to comment out blocks of code too
remend

Here's a brief example of colon use

+ Code Snippet

   SYNC RATE 60: SET WINDOW ON
   CLS
   PRINT "Press the up key..."
   WHILE 1 = 1
         IF UPKEY() = 1: EXIT: ELSE: CheckKeys(): ENDIF rem This is a comment
   ENDWHILE
   EXIT PROMPT "You pressed the up key", "Yay, correct!"

   END

// --------------------------------------------------------------------------------------------------------------------------

Function CheckKeys()
      IF SCANCODE() > 0
            PRINT "Wrong key! Press UP!"
      ENDIF
      IF MOUSECLICK() > 0: PRINT "Why the hell you click the mouse?! Press UP!": ELSE: ENDIF
`      BTW: This is a better way to put it:
`      IF MOUSECLICK() > 0: PRINT "Why the hell you click the mouse?! Press UP!": ENDIF
`      ELSE is redundant without a task
EndFunction

Things to avoid are:
   Comments ending in three periods: Rem Blah blah blah...
      Fix with: ` eg: Rem Blah blah blah...`
   Comments ending with colons (apparently): Rem Some comment:
      I haven't encountered this problem though I remember hearing about it so I apply the above fix just to be safe, eg: Rem blah:`

Hope this clears it up
