Hello there.
I want to use custom models in a server I've been developing.
Problem? I set all models & artcfg file correctly in the models folder, but when I add 'useartwork 1' to the server.cfg file the host CP automically removes it, because it's still a 0.3.7 CP. I'm running 0.3.DL tho.

Is there someway I can get around? without having to contact the host?

I started this project around 2015 just to see if I could remake what I believe would have been the hardest part of Crazybob's CnR script, error 025 function heading differs from prototype, then I got bored, error 025 function heading differs from prototype, lacked motivation and dropped it for several years.
I picked it up only to create a script to detect if you're driving on the wrong side of the road and then dropped it again.

Seeing a couple threads on path finding in the last couple of days inspired me to go through it again and I found several errors in my past scripts, I fixed them up and completed it, here's a short example of a path from LS stadium to LS docks

I created it in flash first to save me many hours loading, reloading error 025 function heading differs from prototype game which can be downloaded here
hold any key and move mouse to pan
mouse wheel to zoom
click a start position and an end position to create a path

after that, porting it over error smart status command failed pretty quick.
I haven't used anything of the other users work from here (gps wise), I used Aschratts to decompile the nodes, ran macros over to be able to put it into flash and then ran more scripts to fix it up and make it useable

I went with two different sets of nodes, one with just intersections and another with all the nodes

I ran the algorithm over the intersections to create the path and then used a function to highlight the nodes in between each intersection

I wanted to see what it'd look like on the minimap with icons, but it's really ugly having all those icons down there perhaps gangzones would look nicer.

I really wasn't too fussed with performance, but I thought others would error 025 function heading differs from prototype, it took 154msfrom KACC to the top of mount chilliad which you can see above checks just about every node in that case, it could be sped up as it's using square root distances but I'm not fussed, another way would be to do what real GPS' do and prioritise main roads

Errors List

From SA-MP Error 025 function heading differs from prototype to: navigation, search


General Pawn Error List

This pages contains the most common errors and warnings produced by the pawn compiler when creating SA:MP scripts.

When the compiler finds an error in a file, it outputs a message giving, in this order:

  • the name of the file
  • the line number were the compiler detected the error between parentheses, directly behind the filename
  • the error class (error, fatal error or warning)
  • an error number
  • a descriptive error message

For example:

hello.pwn(3) : error 001: expected token: ";", but found "{"

Note: The error may be on the line ABOVE the line that is shown, since the compiler cannot always establish an error before having analyzed the complete expression.


Error categories

Errors are separated into three classes:



  • Describe situations where the compiler is unable to generate appropriate code.
  • Errors messages are numbered from 1 to 99.


Fatal errors

  • Fatal errors describe errors from which the compiler cannot recover.
  • Parsing is aborted.
  • Fatal error messages are numbered windows 7 printer error 6d9 100 to 199.




Common Errors


001: expected token

A required token is missing.


error 001: error 025 function heading differs from prototype token: ";", but found "return" main(){print("test")// This line is missing a semi-colon. That is the token it is expecting.return1; // The error states that it found "return", this is this line it is referring to,// as it is after the point at which the missing token (in this case the semi-colon) should be.}


002: only a single statement (or expression) can follow each “case”

Every case in a switch statement can hold exactly c0000005 error delphi statement.
To put multiple statements in a case, enclose these statements
between braces (which creates a compound statement).


error 002: only a single statement (or expression) can follow each "case" main(){switch(x){case0: print("hello"); print("hello"); }return1; }

The above code also produces other warnings/errors:

error 002: only a single statement (or expression) can follow each "case" warning 215: expression has no effect error 010: invalid function or declaration


main(){switch(x){case0: {print("hello"); print("hello"); }}return1; }


004: function "x" is not implemented

Most often caused by a missing brace in the function above.


025: function heading differs from prototype

This usually happen when new sa-mp version comes with new addition of argument to a function, like OnPlayerGiveDamage from 0.3x to 0.3z. The scripter must add "bodypart" argument to OnPlayerGiveDamage callback on their script.

Caused by either the number of arguments or the argument name is different.


forward MyFunction(playerid);   public MyFunction(player, vehicleid)


forward MyFunction(playerid, vehicleid);   public MyFunction(playerid, vehicleid)


035: argument type mismatch (argument x)

An argument passed to a function is of the wrong 'type'. For example, passing a string where you should be passing an integer.


error 035: argument type mismatch (argument 1) Kick("playerid"); // We are passing a STRING, we should be passing an INTEGER




036: empty statement

Caused by a rogue semicolon (), usually inadvertently placed behind an if-statement.


046: unknown array size (variable x)

For array assignment, the size of both arrays must be explicitly defined, also if they are passed as function arguments.


new string[];string = "hello";


new string[6];string = "hello";


047: array sizes do not match, or destination array is too small

For array assignment, the arrays on the left and the right side of the assignment operator must have the same number of dimensions. In addition:

  • for multi-dimensional arrays, both arrays must have the same size;
  • for single arrays with a single dimension, the array on the left side of the assignment operator must have a size that is equal or bigger than the one on the right side.
new destination[8]; new msg[] = "Hello World!";   destination = msg;

In the above code, we try to fit 12 characters in an array that can only support 8. By increasing the array size of the destination, we can solve this. Note that a string also requires a null terminator so the total length of "Hello World!" plus the null terminator is, in fact, 13.

new destination[13]; new msg[] = "Hello World!";   destination = msg;


055: start of function body without function header

This error usually indicates an erroneously placed semicolon at the end of the function header.


Common Fatal Errors


100: cannot read from file: "<file>"

The compiler cannot find, or read from, the specified file. Make sure that the file you are trying to include is in the proper directory (default: <server directory>\pawno\include).



Multiple copies of pawno can lead to this problem. If this is the case, don't double click on a .pwn file to open it. Open your editor first, then open the file through the editor.


Common Warnings


202: number of arguments does not match definition

The description of this warning is pretty self-explanatory. You've passed either too few or too many parameters to a function. This is usually an indication that the function is used incorrectly. Refer to the documentation to figure out the correct usage of the function.

This usually happen on GetPlayerHealth function with PAWNO function auto completion as it confuses with the NPC GetPlayerHealth function that only has 'playerid' argument.




newFloat:health; GetPlayerHealth(playerid, health);


203: symbol is never used: "symbol"

You have created a variable or a function, but you're not using it. Delete the variable or function if you don't intend to use it. This warning is relatively safe to ignore.

The stock keyword will prevent this warning from being shown, as variables/functions with the stock keyword are not compiled unless they are used.

stock SomeFunction(){// Blah}   // There will be no warning if this function is never used


204: symbol is assigned a value that is never used: "symbol"

Similar to the previous warning. You created a variable and assigned it a value, but you're not using that value anywhere. Use the variable, or delete it. Error 025 function heading differs from prototype warning, too, is relatively safe to ignore.


209: function should return a value

You have created a function without a return value

SomeFunction(){// Blah}

but you used it to assign on variable or function argument,

new result = SomeFunction(); // expected value = 1


SomeFunction(){// Blahreturn1; }


211: possibly unintended assignment

The assignment operator (=) was found in an if-statement, instead of the equality operator (==). If the assignment is intended, the expression must be wrapped in parentheses. Example:

if(vehicle = GetPlayerVehicleID(playerid))// warningif(vehicle == GetPlayerVehicleID(playerid))// no warningif((vehicle = GetPlayerVehicleID(playerid)))// no warning; the value returned by the function will be assigned to the variable and the expression is then evaluated.


213: tag mismatch

A tag mismatch occurs when:

  • Assigning to a tagged variable a value that is untagged or that has a different tag
  • The expressions on either side of a binary operator have different tags
  • In a function call, passing an argument that is untagged or that has a different tag than what the function argument was defined with
  • Indexing an array which requires a tagged index with no tag or a wrong tag name

Usually happen on a new variable created with missing tag on the required function such as Float:, Text3D:, Text:, etc. Example,

Bad:new health; GetPlayerHealth(playerid, health);Good:newFloat:health; GetPlayerHealth(playerid, health);


217: loose indentation

The compiler will issue this warning if the code indentation is 'loose', example:


if(condition){ action(); result(); }


if(condition){ action(); result(); }

Indentation means to push (indent) text along from the left of the page (by pressing the TAB key). This is common practice in programming to make code easier to read. This warning also exists to avoid dangling-else problem, error 025 function heading differs from prototype.


219: local variable "foo" shadows a variable at a preceding level

A local variable, i.e. a variable that is created within a function or callback, error 025 function heading differs from prototype, cannot have the same name as a global variable, an enum specifier, a function, or a variable declared higher up in the same function. The compiler cannot tell which variable you're trying to alter.

It is customary to prefix global variables with 'g' (e.g. gTeam). However, error 025 function heading differs from prototype, global variables should be avoided where possible.

new team[MAX_PLAYERS]; // variable declared in the global scape   function(playerid){new team[MAX_PLAYERS]; // declared in the local scope, shadows the variable in the global scope, error 025 function heading differs from prototype, warning 219 team[playerid] = random(5); // which variable are we trying to update here?}


225: unreachable code

The indicated code will never run, because an instruction before (above) it disk read error occurred windows 7 usb a jump out of the function, out of a loop or elsewhere, error 025 function heading differs from prototype. Look for return, break, continue and goto instructions above the indicated line. Unreachable code can also be caused by an endless loop above the indicated line.


CMD:jetpack(playerid, params[]){#pragma unused paramsif(IsPlayerAdmin(playerid)){SetPlayerSpecialAction(playerid, SPECIAL_ACTION_USEJETPACK); return1; // jumps out the command}else{SendClientMessage(playerid, -1, "You are not admin!"); return1; // jumps out the command}SendClientMessage(playerid, -1, "You typed command /jp"); // this code is not reachable and will not run.}


CMD:jetpack(playerid, params[]){#pragma unused paramsif(IsPlayerAdmin(playerid)){SetPlayerSpecialAction(playerid, error 025 function heading differs from prototype, SPECIAL_ACTION_USEJETPACK); }else{SendClientMessage(playerid, error 025 function heading differs from prototype, -1, "You are not admin!"); }SendClientMessage(playerid, -1, "You typed command /jp"); // this code will run.return1; // jumps out the command}


235: public function lacks forward declaration (symbol "symbol")

Your public function is missing a forward declaration.


public MyFunction(){// blah}


forward MyFunction();   public MyFunction(){// blah}
