This tutorial explains how to write advanced modules in C. It is assumed you know how to code and are familiar with how the ASSS code works.

This tutorial is a continuation of Writing Modules In C.

Passing Data To Timers

Write me!

typedef struct ThisIsData
{
	Player *p;
	int number;
} ThisIsData;

local int timerfunc(void *vp) //vp is void pointer, just an address that can point anywhere
{
	ThisIsData *tid=(ThisIsData*)vp; //we know it points to our data
	
	if(tid->number == 10)
	{
		//if it worked anything in here will work too
	}

	return 0; //return 1 if you want timer to run again, or 0 if you want it to be removed
}

anotherfunction()
{
	ThisIsData *tid=amalloc(sizeof(ThisIsData)); //we must allocate memory because anything in this function is destroyed when it ends

	tid->number=10

	ml->SetTimer(timerfunc,1000,100,tid,0); //now set timer to activate in 1000 centiseconds, then repeat every 100. we are also sending the address of tid
}


Passing Multiple Arguments To Commands

Commands do not have to be in order. Write me!

local void examplecommand(const char *command, const char *params, Player *p, const Target *t)
{
	char *sentence=strdup(params); //strdup clones a string because strtok replaces " " with a \0
	char* word=strtok(params," "); //strtok reads everything until next \0 into word
	
	while(word) //while word != null
	{
		if(!strnicmp(word,"a=",2))
		{
			//do stuff if first 2 letters of word are 'a' then '='

			word+=2; //like move start of word 2 letters forward
			int check=atoi(word); //then read a number
		}
		else if(!strnicmp(word,"bc=",3))
		{
			//do stuff if first 3 letters of word are 'b' then 'c' then '='

			word+=3; //make sure you move it 3 letters and not 2
			int check=atoi(word); //then read a number
		}
		else if(!stricmp(word,"-de"))
		{
			//do stuff if word is "-de"
		}
		word=strtok(NULL," "); //advance to next word, or set word to null if none left
	}
}
