i just downloaded these halo 2 tags from this website and when i try them out, some of the download weapons, only some, had absolutely no ammo at all when i picked it up. how do i add ammo to the weapon?

in the weapon tag, go to magazines (in guerilla), you should find fields for ammo.

^That sets the amount of ammo. To actually spawn it with ammo, in Sapien, select the weapon you put down. In the Properties Pane, set the amount of rounds loaded, and total amount of rounds.

So since you select the number of rounds loaded, does that mean that you could spawn an assault rifle that is only half loaded? (Forgive my ignorance, but I am curious.)

I think so.

Yes.

do you must step on a trigger volume to activate a cutscene or save the game? if yes, plz tell me how to ut more trigger volumes but still when you step on either one of them, you can still triger the cutscene or game save

Basically, trigger volumes are used to detect whether someone's inside it. But you can save the game at any time. If you want to save when you enter a trigger volume, check the other topic for the script. You can place as many trigger volumes as you wish, and name them whatever you want. For cutscenes, just use:

(script startup cutscene
(sleep_until (volume_test_objects tvol (players)) 15)
(player_enable_input 0)
[insert cutscene script here]
(player_enable_input 1)
)

Insert your cutscene script in place of the [insert cutscene script here]. This script works assuming that your trigger volume is called tvol. If it isn't replace the tvol with the name of the trigger volume. The (player_enable_input 0) disables input from the player, so the player can't run around killing everyone. (player_enable_input 1) allows input, so he can move again.

you have to goto item collection under NETGAME EQIPMENT

He's asking about .weapon tags now, not netgame equipment. I'm assuming he's doing SP.
