I have two enemy tanks which i would like to see going round and round forever(well until i shoot them with my tank).

I have put down my info_vehiclepoint (tank1_path) which links to t1 info_vehiclepoint t2 ...etc etc but when it reaches the start again(tank1_path) my tanks stop.How do i get them to keep on going round and round?

heres my tank script

thread go_tanks

level waitTill prespawn

level.fastspeed = 300
level.slowspeed = 160

$playertank waitthread global/vehicles_thinkers.scr::players_tank
$playertank vehiclespeed level.slowspeed
level.currently_fast = 0

exec global/ambient.scr m5l2a

level waitTill spawn

speedup:
if (level.currently_fast == 1)
end

for (local.speed = level.slowspeed; local.speed <= level.fastspeed; local.speed += 1)
{
$playertank vehiclespeed local.speed
waitframe
}

level.currently_fast = 1
end

slowdown:
if (level.currently_fast != 1)
end

for (local.speed = level.fastspeed; local.speed >= level.slowspeed; local.speed -= 1)
{
$playertank vehiclespeed local.speed
waitframe
}

level.currently_fast = 0
end

drive_path local.path local.speed local.remove:
self.driving = 1
self drive local.path local.speed 30 200 level.lookahead
self waitTill drive
if (self)
{
self stop
self.driving = 0
if (local.remove == "remove")
self remove
}
end

(ps.) ive copied most of it from a breathrough script and chopped and changed bits but it all works ok(for me that is,lol)

Make sure the last node of the path targets the first one.

once you get this part done properly with a thread name for example for the thread then you can loop it as long as the tank has not been destroyed
