The following code produces the error:

Quote: "ENDFUNCTION and EXITFUNCTION must return the same data type at line ..."


However, both IntArray(0) and n are clearly (and explicitly defined as) integers.

I find returning arrays not a fun thing in DBP.

Why make sense when you could make brownies?

DBPro most likely interprets arrays like "IntArray(0)" as DWORD pointers and not integer values. Functions in dbpro need to end a function with the same variable type. In your case you'd need to do something like:

And for testing purposes I tossed in these commands and ran it through the dbpro debugger.

Executed perfectly.

When this 'difficulty' appeared during an upgrade and broke some code I had, I just added 0 to the number and that solved the problem.

In many languages, it is standard that an array identifier that is followed by a subscript suffix will resolve to the array element that the subscript index maps to. If DBPro breaks this convention, then it isn't documented anywhere in its help files.

Sure, there are a number of ways to resolve the issue, but I won't bow to this 'workaround' mentality unless 'bugs' such as these do in fact turn out to be the intended behaviour of the language.

Added additional text to the help to clarify this:

ENDFUNCTION:
EXITFUNCTION:
It is vital that if exit function command is used within a function declaration, that the return types are identical not only in data type, but whether they are arrays, variables or literals. You also cannot have expressions as part of the return data.

strange as i get this
Command out of place at line 139.

with this code

function moveplayer()
if upkey()=1
playerspeed(player) = playermaxspeed(player)*1
ENDIF
if downkey()=1
playerspeed(player) = playermaxspeed(player)*-1
ENDIF
curangle = playerangle(player)
if leftkey()=1 and playerspeed(player)>0
playerangle(player) = curangle +5
if playerangle(player) >360
playerangle(player) = 5
ENDIF
if leftkey() = 1 and playerspeed(player)<0
playerangle(player) = curangle -5
if playerangle(player) <0
playerangle(player) = 355
endif
ENDIF
if rightkey()=1 and playerspeed(player)>0
playerangle(player) = curangle -5
if playerangle(player)<0
playerangle(player) = 355
endif
ENDIF
if rightkey() = 1 and playerspeed(player)<0
playerangle(player) = curangle +5
if playerangle(player) >360
playerangle(player) = 5
endif
endif
ENDFUNCTION
line 139 is ENDFUNCTION
is there something missing in the function(if there is i can't find it)
or is it a bug

Indent your code and it will make it easier to read and find bugs.

It looks like you missed an ENDIF here:
