This function can disable or enable an element's collisions. An element without collisions does not interact with the physical environment and remains static.
Note: This function has unwanted effects on vehicles with drivers at the moment.

Syntax

bool setElementCollisionsEnabled ( element theElement, bool enabled )

Required Arguments

  • theElement: The element you wish to set the collisions of
  • enabled: A boolean to indicate whether collisions are enabled (true) or disabled (false)

Returns

Returns true if the collisions were set succesfully, false otherwise.

Example

This example disables collisions for all vehicles within a certain radius of a player:

Client
function disableVehicleCollisionsNearPlayer(thePlayer, maxDistance)
	local playerX, playerY, playerZ = getElementPosition(thePlayer)
	local vehicles = getElementsByType("vehicle")
	for k,v in ipairs(vehicles) do
		local vehicleX, vehicleY, vehicleZ = getElementPosition(v)
		-- get the distance between the player and the vehicle:
		local distance = getDistanceBetweenPoints3D(vehicleX, vehicleY, vehicleZ, playerX, playerY, playerZ)
		if (distance <= maxDistance) then
			-- disable collisions for the vehicle
			setElementCollisionsEnabled(v, false)
		end
	end
end
