Ok superfriends,

I have the javelin anti-tank gun working. The scripting is pretty darn simple. The real issue is the materials required for the zone file- which of course are not automatically suggested like all the other assets, so it took a bit of hunting to find them.

Here's the code:

//set up teh jav target
tank = getent("auto64", "targetname"); 
OFFSET = ( 0, 0, 60 );
target_set( tank, OFFSET );
target_setAttackMode( tank, "top" ); //not quite sure what this does. -RTH
target_setJavelinOnly( tank, true );

Here is what is needed for your zone file:

material,hud_javelin_bg
material,hud_javelin_clu_on
material,hud_javelin_day_on
material,hud_javelin_dir_on
material,hud_javelin_lock_box
material,hud_javelin_lock_on
material,hud_javelin_night_on
material,hud_javelin_norocket_on
material,hud_javelin_rocket_on
material,hud_javelin_top_on
material,hud_objective_tank
material,hud_offscreenobjectivepointer
material,javelin_hud_target
material,javelin_hud_target_offscreen
material,javelin_overlay_grain

Presto! You can now blow up tanks in a very impressive manner.

sounds cool thanks for the post.

thanks i needed this

undefined is not an entity with the exact script you posted.. i have the same targetname.

are you using a tank of some type?

I am using the following entity with the following key value pairs:

classname script_vehicle
model vehicle_t72_tank
script_team axis
targetname auto64
vehicletype t72

Are you doing a precache on the vehicle itself? If not, you'll
need something like this in your global scripts section of your .gsc:

maps\_t72::main( "vehicle_t72_tank" );

In any event, the issue is most likely with tank = getent, as it is saying that your vehicle doesn't have a key value pair of targetname/auto64 (undefined meaning that you are trying to reference a field in your entity that doesn't exist).

Hope it works out for you.

P.S.: Known issue: I've noticed when I blow up a tank with the javelin, it spawns an "extra" tank cannon and head. I think in the IW scripts they do some kind of delete function to make this look correct. Just an FYI.

I double checked everything, target names, script_vehicle, the script, precaching.

Gives me the same crap.. :(

Do you have this in your global scripts as well:

maps\_javelin::init();

And do you have this at the very top with your #includes:

#include maps\_vehicle;

That's the only thing I can see that could be holding you up.
After that, I'm afraid I can only tell you to look at the bog .gsc files to see how IW did it.

now i get 'type undefined is not an entity' on target_set( tank, OFFSET );

Do you directly place your tank in the world or is it spawned in with a trigger? That could make a difference if the tank hasn't been spawned yet, it wouldn't see it as a legit actor.

before calling up the thread that sets up the javelin target, make sure you spawn your tank first. Put this in a seperate thread:


maps\_vehicle::create_vehicle_from_spawngroup_and_gopath( 1 );

also make sure your tank has the key: script_vehiclespawngroup
value: 1

change the number to your liking
