[TUT] Debugging a freezing script (my method)

[JDMAlex]

My method to finding why your script freezes if there is a better method than this I would like to know! but this one seems pretty good for now

what you need:
below is the code I use currently that displays a message "break" for every line I put it on and also displays a message to press X to continue the loading process.

#define DEBUG // If you have this at the top it will allow debug message to show , if you remove it they will be hidden/non function.

void DebugBreak(char *sMessage){
#ifdef DEBUG
	PRINT_STRING_WITH_LITERAL_STRING_NOW("STRING", sMessage , 5000, 1);
	WAIT(800);
	PRINT_STRING_WITH_LITERAL_STRING_NOW("STRING", "DEBUG BREAK , PRESS X TO CONT" , 5000, 1);
	while(!IS_BUTTON_JUST_PRESSED(0,X)) WAIT(0);
#endif
}

Now what I do is in every line from top to bottom (when I get a freeze) I insert DebugBreak("Name_To_display"); on top of the native or code being executed
like this:

example

void CheckPlayer(void){
DebugBreak("DOES_CHAR_EXIST");
	if(DOES_CHAR_EXIST(GetPlayerPed())){
DebugBreak("IS_CHAR_DEAD");
		if (IS_CHAR_DEAD(GetPlayerPed())){
                DebugBreak("DOES_CHAR_EXIST  ");
			if(DOES_CHAR_EXIST(GamePed)){
                              DebugBreak("etc  ");
				EXPLODE_CHAR_HEAD(GamePed);
                              DebugBreak("etc  ");
				TASK_DIE(GamePed);
                              DebugBreak("etc  ");
				if(DOES_BLIP_EXIST(GamePedBlip))     DebugBreak("etc  ");REMOVE_BLIP(GamePedBlip);
				if(DOES_BLIP_EXIST(Base))     DebugBreak("etc  ");REMOVE_BLIP(Base);
				GameSwitch = 0;
			}
		}
	}
}

thats pretty much it , compile it / run it / press x when it says and pay attention to the key words you picked to pinpoint you to the exact moments you freeze!

I'm amazed I didn't think of this before! Nice JDM.

there is an opcode for catching errors in the game(opcode 73), but im guessing scocl hadnt been designed with that feature in mind

but thats a nice bit of code you have there anyway.
what i usually did was just use print("1"); print(2); etc before each statement i thought would cause me to freeze out, but this definitely looks a more professional way of doing it

[JDMAlex]

yeh , I also did it that way but sometimes I would forget to pay attention to the number but that opcode sounds better

[MaxSpeed]

This is pretty much how I did it. Nice tut

[JDMAlex]

thanks , I hope others can get passed there issues by using this
