Syntax

OOP Syntax Help! I don't understand this!
- Method: Projectile(...)
Required Arguments
- creator: The element representing creator of the projectile. In case you want the projectile to be synced for everybody creator must be the local player or his vehicle.
- weaponType: int representing the projectile weaponType (characteristics). Valid IDs are:
| ID | Name/Description |
|---|---|
| 16 | Grenade |
| 17 | Tear Gas Grenade |
| 18 | Molotov |
| 19 | Rocket (simple) |
| 20 | Rocket (heat seeking) |
| 21 | Air Bomb |
| 39 | Satchel Charge |
| 58 | Hydra flare |
Optional Arguments
NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.
- posX, posY, posZ: float starting coordinates for the projectile. They are coordinates of creator by default.
- force: float representing the starting force for throwable projectiles.
- target: element target used for heat seeking rockets.
- rotX, rotY, rotZ: float starting rotation for the projectile.
- velX, velY, velZ: float starting velocity for the projectile.
- model: Integer representing the projectile's model, uses default model for weaponType if not specified.
Returns
Returns a projectile element if projectile creation was successful. Returns false if unable to create a projectile (wrong weapon ID or projectiles limit was reached).
Example
This example makes a rocket minigun (minigun shooting with rockets).
function onClientPlayerWeaponFire(weaponID, weaponAmmo, weaponAmmoInClip, hitX, hitY, hitZ, hitElement)
local minigunWeapon = (weaponID == 38) -- check if player is using minigun
if (not minigunWeapon) then
return false -- he doesn't, so don't continue
end
local playerX, playerY, playerZ = getElementPosition(source) -- get position of player
local projectileType = 19 -- type of projectile
local projectileForce = 200 -- force used for projectile
local rocketProjectile = createProjectile(source, projectileType, playerX, playerY, playerZ, projectileForce) -- create rocket projectile
if (not rocketProjectile) then -- if projectile limit is reached
outputChatBox("Rocket minigun overheated! Give it a rest pal!", source) -- output a message
end
end
addEventHandler("onClientPlayerWeaponFire", localPlayer, onClientPlayerWeaponFire)
This example code shoots a projectile from your occupied vehicle that travels in the direction your vehicle is facing when you press vehicle_fire (left mouse button with default controls)
function shootProjectile()
local playerVehicle = getPedOccupiedVehicle(localPlayer)
if (not playerVehicle) then -- only create projectile if we are inside a vehicle
return false
end
local projectileType = 19 -- rocket
local vehicleX, vehicleY, vehicleZ = getElementPosition(playerVehicle)
createProjectile(playerVehicle, projectileType, vehicleX, vehicleY, vehicleZ)
end
bindKey("vehicle_fire", "down", shootProjectile)
Issues
| Issue ID | Description |
|---|---|
| #584 | createProjectile creates one projectile for every person in the vehicle |
| #616 | Projectile rotation is set exactly opposite for creator |
