CallNativeFunction

Description

Sends a callback to the engine to run a native function. There are three versions of the function that can be used depending on the amount of parameters needed for the callback:

• CallNativeFunction (no parameters)
• CallNativeFunction2 (two parameters)
• CallNativeFunction4 (four parameters)

In order to call a native function by name, a global variable named after the function must be added to the GameConfig. Once added, the engine will automatically set the value of the global variable to the ID of the native function.

Parameters

callback

The index value of the callback.

param1, param2, param3, param4

Parameters to use for the callback.

Return Value

Depends on the callback used.

Syntax

CallNativeFunction(int callback)

CallNativeFunction2(int callback, param1, param2)

CallNativeFunction4(int callback, param1, param2, param3, param4)

Examples

CallNativeFunction(Disconnect2PVS)

CallNativeFunction2(TransmitGlobal, "vs.randomValue", vs.randomValue)

CallNativeFunction4(NotifyCallback, NOTIFY_STATS_ENEMY, StageStatsUsabilityParam1, StageStatsUsabilityParam2, StageStatsUsabilityParam3)
