De-targeting players

Bilko · Post by **Bilko** » Tue Jul 29, 2003 6:39 pm

I followed the tutorial on the manstein site for the flak88 autofire. Works great. However, I think theres a problem with targeting. I adapted and built upon it...

My MG is based on a trigger_multiple to aim and fire at the player and when I enter the trigger zone it does so, kills me and all seems fine. However, when I respawn the MG is still following me even outside the trigger zone, then, whoever enters the trigger zone it still fires at me.

Similarly, I have 4 flak88 on the same principle (trigger_multiple). They seem to work fine until there is more than one player in the game and when there is they, they do not work at all.

Also, with the MG in the game, the flak88s dont seem to work at all.
I can post my script if you want but its quite long.

Any ideas? I think it needs to be able to destinguish between different players, but I could be wrong.
I'm new to scripting so this could be totally wrong and any and all help is greatly appreciated. Thanks.

Bilko.

Well, I'm afraid no one will be able to help you unless you post at least some parts of the script...

Sorry, here it is. I have 4 flak88. I think you can guess their names etc:

//-------------------------------------------------

This fires 'em one after another (not sure why) but last time I tested, when theres more than one person they do nothing. I think it's 'cos they can't distinguish between different players and so do nothing, not sure though.

This is why it doesn't work with more than one player:

local.target = $player
// $player is a listener if there's one player
// $player is an array if there are more players

//Set target
local.gun_name setaimtarget local.target
// gun can aim at any listener with an origin (simpleentity)
// gun can't aim at an array -> 'cannot cast array to listener' error

One flak can't possibly aim at more than one player simultaneously.

OK, I understand that, thats kinda what I was thinking, but can I overcome it?

if you want it to target a random player, do this:

level.players = $player.size //how many players are there?
local.diedamit = (randomint (level.players) + 1) //random ints start with 0, and theres no $player # 0, so add 1 to whatever you get.

$gun1 setaimtarget local.diedamit
$gun1 waittill ontarget
$gun1 startfiring
//blah blah blah

it would have to be more complex, for example, this thing here will track people through walls and just shoot.. i made a tank script that works great, you can ambush it and all, but im too lazy to fix it..

OK, thanks, but really I need it when someone enters the trigger_multiple. Could that bit of script be adapted?

Post by **jv_map** » Wed Jul 30, 2003 10:21 am

You can use if(local.player isTouching $mytrigger), but you'd also have to check if the player isn't spectating

Bilko · Post by **Bilko** » Wed Jul 30, 2003 10:55 am

How would I use that? Sorry, I'm new to all of this

Bilko.

nuggets · Post by **nuggets** » Wed Jul 30, 2003 12:15 pm

if ((local.player isTouching $mytrigger) && !(local.player.dmteam == "spectator"))

Bilko · Post by **Bilko** » Wed Jul 30, 2003 1:28 pm

Sorry, I meant how would I use that in my script?

bdbodger · Post by **bdbodger** » Wed Jul 30, 2003 3:21 pm

couldn't you use something like this since you are useing a setthread

local.guntarget=parm.other

while(local.guntarget istouching self)
{
$gun1 setaimtarget local.guntarget
.....
.....
}

$gun1 setaimtarget null // ?

Bilko · Post by **Bilko** » Wed Jul 30, 2003 5:13 pm

sounds feasible, ill give it a try.

Bilko · Post by **Bilko** » Wed Jul 30, 2003 6:14 pm

Thanks a lot everybody, especially bdbodger, it works superbly!
If you're interested I'll post the script to you.
Thanks guys!

may sound like a really stupid question but give it some thought before answering...

if someone will only trigger this when they're in the trigger... why use iftouching? they'll always be touching the trigger
