It happens often on my racing server. I set HP for players in callbacks like exit vehicle. To avoid this I must use '-noanticheat' parameter.

Kicking player '[DnA]Gudio' (0), health increased from 93 to 100.

Sometimes I can enter 5 checkpoints and then the server is crashed.
My script removes current CP and immediately creates a new one. I guess that's the reason.

First of all we need a function called random which accepts minimum and maximum values in its parameters:

Code Select Expand

function random( min, max )
{
if ( min < max )
return rand() % (max - min + 1) + min.tointeger();
else if ( min > max )
return rand() % (min - max + 1) + max.tointeger();
else if ( min == max )
return min.tointeger();
}
then we must add a table responsible for deleting pickups when they're picked up:

Code Select Expand

wepPickups <- {};
next we need a function which will be used in onPlayerDeath/onPlayerKill/onPlayerTeamKill events. (DIY)

Code Select Expand

function CreatePlayerWeaponPickups( player )
{
for ( local i = 0, world, pos, pickup, weapon; i < 7; i++ )
{
world = player.World;
weapon = player.GetWeaponAtSlot( i );
player.World = player.UniqueWorld;

if ( weapon > 0 && weapon != 16 )
{
pos = player.Pos;
pos.x = random( pos.x - 2, pos.x + 2 );
pos.y = random( pos.y - 2, pos.y + 2 );

pickup = CreatePickup( 258 + weapon, world, player.GetAmmoAtSlot( i ), pos, 255, true );
if ( pickup )
wepPickups.rawset( pickup.ID, pickup );
}
}
}
finally, onPlayerClaimPickup must return true:

Code Select Expand

function onPickupClaimPicked( player, pickup )
{
if ( player.Health > 0 && wepPickups.rawin( pickup.ID ) )
{
PlaySound( player.UniqueWorld, 78, player.Pos );

wepPickups.rawdelete( pickup.ID );
pickup.Remove();

return 1;
}

return 0;
}
_/
Feel free to add a timer to delete pickups after some time.

Since onPlayerGameKeysChange callback has been added to 0.4's squirrel module, you can write for example a nice spectator mode with sprites or textdraws that show what keys are pressed by the player at the moment.
Function is provided below:

Code Select Expand

onfoot <- [ KEY_ONFOOT_FORWARD, KEY_ONFOOT_BACKWARD, KEY_ONFOOT_LEFT, KEY_ONFOOT_RIGHT, KEY_ONFOOT_JUMP, KEY_ONFOOT_SPRINT, KEY_ONFOOT_FIRE, KEY_ONFOOT_CROUCH, KEY_ONFOOT_PUNCH, KEY_ONFOOT_PREVWEP, KEY_ONFOOT_NEXTWEP, KEY_ONFOOT_AIM ];
incar <- [ KEY_INCAR_LEFT, KEY_INCAR_RIGHT, KEY_INCAR_BACKWARD, KEY_INCAR_FORWARD, KEY_INCAR_HORN, KEY_INCAR_LEANUP, KEY_INCAR_LEANDOWN, KEY_INCAR_LOOKLEFT, KEY_INCAR_LOOKRIGHT ];


function getPressedKeys( keysFlag, isOnFoot )
{
local table, pressedKeys = {}, i = 0;


if ( isOnFoot )
table = onfoot;
else
table = incar;


foreach ( key in table )
{
if ( key <= keysFlag )
{
pressedKeys.rawset( i++, key );
keysFlag -= key;
}
}


return pressedKeys;
}
Have fun and grab the latest version of squirrel module here.

This issue was reported by me like a year ago to maxorator and I thought he fixed it, but today I've noticed the same again.
Removed pickups sometimes are still visible on the screen, but on the server-side they don't exist anymore. They aren't rotating and have strange alpha.

I have recorded it, so you will understand what I was talking about.

Last update fucked up ghost vehicles. When there is a driver in the car, ghost state doesn't work and all collisions are enabled.
