Graal Tutorials -- Triggeraction

The triggeraction command is used for making npcw's
interact with other players and/or npcs.

For the npcw to interact with another player that player
must also have the npc. If you want it to work with all
players put the scripting into a system npc or make
players pick up the npcw.

Ill use bread making for the example of npcw to npc
interaction as nothing else springs to mind.

-------------------------------------------------
//The NPC Weapon

if(playertouchsme) //or another event happens
{
toweapons itemname; //name of the npcw
breadmaking=2; //This is used to set how quick the bread making will
go. At the moment it will increase by 2 each time the npcw is used.
} //anything else added in there is optional eg. hide;

if(weaponfired) //when the player uses the npcw
{
freezeplayer 0.5; //This is used so the player can only use the npcw
every so often so that the bread is not made in a couple of seconds.
//Other things could be added here. eg. setani
triggeraction playerx+1.5+vecx(playerdir)*2,playery+1+vecy(playerdir)*2
//the coordinates npcs needs to be at to interact. The coordinates
stated are for if the npc is just in front of the player.
,bread //the name of the action
,#v(breadmaking); //The variable that sets how quick the bread making
will go. This was set earlier.
}

-------------------------------------------------

Then you need the npcs.

-------------------------------------------------
//The NPC

if (actionbread //the action that was set in the npcw
&& this.breadpercent<=99) //Only increases the this.flag while it is
less than 100.
{
breadmaking = strtofloat(#p(0)); //sets the action paremeter.
this.breadpercent+=breadmaking; //increases the this.breadpercent
flag by 2 (as this is what the breadmaking variable is set to)
message #v(this.breadpercent)%; //optional - shows the perecentage
done
}

if (this.breadpercent>=100) //when the percentage reaches 100 (or more)
{
setstring bread,#v(strtofloat(#s(bread))+1); //adds 1 to a bread
string.
destroy; //removes the npc
}

-------------------------------------------------

That is a basic script which could be improved up on.
For example changing the graphic file at a certain stage(s).
eg. if (this.breadpercent>=50) {setimg bread50percent.gif;}

The NPC script could also be placed in a text file and then use putnpc.
eg. if(playerchats&&strequals(#c,bread)) {putnpc
bread.gif,bread.txt,30,30}

Here is an example of a npcw that interacts with other players. Only
the npcw is
needed for npcw to player interaction.

-------------------------------------------------
//The NPC Weapon

if (playertouchsme)
{
toweapons Money Steal; //name of the npcw.
}

if (weaponfired) {
triggeraction playerx+1.5+vecx(playerdir)*2,playery+2+vecy(playerdir)*2
,steal,; //same as before but this time there is no variable set and
the action is called steal
}

if (actionsteal) //action was set above
{
this.steal=random(0,9); //sets a this.flag;

if(this.steal<=4 && playerrupees>=1) //If the this.flag is less than 5
(50% chance) and the players rupees are more than 0 then steal will
work
{
playerrupees-=1; //the player who is stolen from loses 1 gralat
lay2 greenrupee,x,y; //1 gralat is dropped onto the floor.
}
}
