I got a script runtime error after I added a sliding door to my map, here is the door script straight from the "Getting started in scripting: moving things":
main()
{
thread door_slider ();
}

door_slider ()
{
door = getent ("slide ", "targetname");
trig = getent ("slider_trigger ", "targetname");
while (1)
{
trig waittill ("trigger");
door movez (80, 2, 0, 0.5);
door waittill ("movedone");
wait (4);
door movez (-80, 2, 0, 0.5);
door waittill ("movedone");
}
}

The console says:

******* script runtime error *******
undefined is not an object: (file 'maps\mp\door1.gsc', line 12)
trig waittill ("trigger")

(file 'maps\mp\door1.gsc', line 3)

I think you are missing


main()
{
maps\mp\_load::main(); <------- this lil bit of coding
thread door_slider();
}

Didn't do a thing... I'm pretty sure the error is in the line "trig waittill ("trigger");"

the error is your answer....

you obviously do not have the entity in your map that has the targetname you are telling it to find and/or it is not a trigger

double check your entity in the map and make sure that you have named it what you are calling it in your script

slider_trigger

Yes, I have a trigger_use in there that has the targetname slider_trigger.

Bump

don't bump the thread that already has your answer or you will find it gets deleted rapidly

double check your entity information as the error you posted says that you DO NOT have trigger in your map with the targetname of slider_trigger

Look, there is a trigger_use next to the door. It has a classname of trigger_use, and a targetname of slider_trigger. I have checked this many times. Now, from my very limited experience with scripting, I think the problem is that there isn't anything named "Trigger", but I'm probobly wrong. I DO know that the trigger_use is named slider_trigger, and I've checked the spelling on that I don't know how many times. Now, the trigger_use is placed over a model. This is just a regular model, but from what I get, that shouldn't be a problem, just thought I'd include it.

to break down your script (the area that we are talking about)

trig = getent ("slider_trigger", "targetname");

this line tells the engine to search the map for an entity that has the targetname of slider_trigger and from this point on refer to it as trig

while (1)

this tells the script that a subloop is going to take place in the following set (defined by an opening and closing curly brace)

{

starts the set

trig waittill ("trigger");

this tells the script to pause and wait until the defined action has occured, in this case wait until the entity defined as trig has been triggered

this is where the error is being generated - basically stating that undefined (trig) is not an object (there is no trigger)

Thanks, that helps me understand scripting a little bit better, I'll try deleting the trigger_use and see if that works.
