i need some help....but i need to be a bit vague..

i m a script noob, but i m trying!


i found a tutorial that told me how to do something once with origins and triggers and the like, now i ve done this and it works great.....trouble is, i want more than one of these things without having tons of scripts....

i ve saved it all as a prefab, and my gsc is in maps/mp and called from the main gsc.

how can i make it so i can use that prefab lots of times with that same script? a targetname for the prefab? then the script using that targetname aswell?

i assume it needs to be something like the explodable barrel scripts....

help appreciated

you can have the same targetname for multiple script objects and access them via script by using getentarray and a for loop.

any chance u could write one for me to select a prefab targetname "faffer" to stick at the top of my script?

i will go through those....but it will have to be later

thanks

note: targetname faffer has to be script_model, script_origin or script_brushmodel. prefabs are no script entity, but can contain such for a more efficient workflow in radiant (duplication)

faffers = getentarray("faffer", "targetname");

for (i=0; i<faffers.size; i++)
{
	faffers[i] thread faffer_think();
}

// ...

faffer_think()
{

	// some example code

	while(1)
	{
		// self is a faffer entity in faffer_think()

		self rotateyaw(90, 3);
		self waittill("rotatedone");

		wait 1;

		self rotateyaw(-90, 2);
		self waittill("rotatedone");

		wait 2;
	}
}

i ve got the script to compile now...but none of my prefabs work now

i don't understand the "faffers" part....whats the purpose of that part of the script?

"prefabs are no script entity"

if its not in a prefab how can i give the whoel thing a targetname instead of all the pieces seperately?



maybe this is beyond me....

if you want to turn a brushes and patches into a script entity, select all desired objects, richt-click, script > script_brushmodel and give the script_brushmodel the targetname faffer

if you want a misc_model to be a script_entity, script > script_model

you can't turn a misc_prefab directly into a script_brushmodel / script_model. you need to enter the prefab or load the prefab .map

also, you can't turn a model into a script_brushmodel, and brushes & patches not into script_models. so if a prefab has models and map geometry you gotta turn them into script entities separately.


you can have script_brushmodels and script_models inside of a prefab and duplicate that prefab as whole for your map.

your map --> prefab --> script_(brush)models

// retrieve an array (set / field / list) containing all script entities having a targetname of "faffer"
faffers = getentarray("faffer", "targetname");

// execute the for-loop body as many times as script entities were retrieved (faffers is the array, faffers.size is the number of entries in it)
for (i=0; i<faffers.size; i++)
{
	// call the function faffer_think, run it threaded
	(will continue code execution without waiting till the other function is done - code parts will be run simultaneously)

	// also pass on one entity of the faffers array
	// i is a counting variable, the for-loop will increase (increment) it by 1 (i++) on every pass

	// single array entries can be accessed by array_name[n], n has to be a number (or a variable storing a number)
	// note that the first element has the number 0 ( array_name[0] )

	faffers[i] thread faffer_think();
}

without using a for-loop, you'd have to do something like this if you had 4 entities targetname=faffer:

faffers = getentarray("faffer", "targetname");

faffers[0] thread faffer_think();
faffers[1] thread faffer_think();
faffers[2] thread faffer_think();
faffers[3] thread faffer_think();

lot of work to write and very inflexible. imagine: if you had 100 entities, you'd have to copy, paste and change the number in brackets 99 times! and if you deleted 5 entities in radiant, you would have to update the script or it would 'cause a ingame error since you'd try to access no more existing entities ( faffers[94] to faffers[99] )

so loops are the smart way, 'cause they are flexible. they don't mind how many entities you have, they do the faffer_think() function call as many times as entities you have in your map (thanks to faffers.size which is used as condition in the for-loop, instructing the script how many passes need to be done to handle all entities). loops can help you to perform actions many times without having to code these actions many times. in your case, a for-loop is used to run code for each array element, whereby an element represents a script_entity here.

my prefab has more than one script_struct in it so it wont convert to a script_model_brushmodel....

so i think the second ones my only option?


thanks for the detailed reply btw!

this is what i ve got....

main()
{


faffers = getentarray("faffer", "targetname");


faffers[0] thread "threadname"();
faffers[1] thread "threadname"();


}

"threadname"()
{

etc etc etc

}


i have 2 prefabs with a targetname of "faffer" and i m just getting "undefined is not an entity"....

i only need about 20 so writing it all seperately is not a problem....i just need it to work with more than one the easiest way possible...

use this instead:

main()
{
	faffers = getentarray("faffer", "targetname");

	for (i=0; i<faffers.size; i++)
	{
		faffers[i] thread faffer_think();
	}
}

faffer_think()
{
	// dunno what you wanna do here...
}

and it won't work if you give the prefab a targetname, you have to turn something into a script_model or script_brushmodel and give that entity the targetname!

what do you want to do with the faffer entities actually?

maybe i cant have more than one then...

the script structs move the player, and they cant be converted to a scriptmodel/brushmodel....

so unless theres another way to force a player to take a path?

why use script structs to move the player?!

is this for SP, COOP or MP? and why you want/need to force the player to take a specific path?
