This function enables or disables asynchronous model loading. Enabling asynchronous model loading may reduce the small pauses that occur when a new model is displayed for the first time. However, it can cause the new models to appear slightly later than they might have otherwise.

[[|link=|]] Warning: Using this function with a large amounts of engineReplace* at the same time may cause loading times to be exponentially slower.


bool engineSetAsynchronousLoading ( bool enable, bool force ) 

OOP Syntax Help! I don't understand this!

Method: Engine.setAsynchronousLoading(...)

Required Arguments

  • enable: Set to true/false to enable/disable asynchronous loading. Only works if the client's preferences has 'Asynchronous Loading' set to 'Auto'.
  • force: If set to true, ignores the client's preferences.


Returns true if the function executed successfully, false otherwise.


The next example enables the model asynchronous loading ignoring client preferences if there are a lot of objects (and the player wants to).

addEventHandler("onClientResourceStart", resourceRoot, function()
    if #getElementsByType("object") > 500 then
	engineSetAsynchronousLoading( true, false )

How it works

If asynchronous loading is disabled, MTA requests all resources to be loaded at the time they have been requested. This will halt game execution for the time being.

Otherwise, all resource requests are queued up on the to-be-loaded queue. At the beginning of the game frame, the GTA:SA streaming system is updated, along with its streaming slicers. This is when a model is loaded after going through multiple stages. Having asynchronous loading disabled forces all stages to be consecutively run through.
