Examples

A function called every frame

In this example function MyFunc will be executed on every frame.

1
2
3
4
5
6

func void Example1()
{
    FF_Apply(MyFunc);
};

func void MyFunc() {};

The easiest and best way to run a function from the beginning is to call FF-Apply directly in the Init_Global (under LeGo_Init), there is a small problem: If the game is loaded, Init_Global is called a second time, the function is added to the list again and is therefore always called twice.

To avoid this effect, you should check whether the function is already active:

1
2
3
4
5
6
7

func void Example1()
{
    if(!FF_Active(MyFunc))
    {
        FF_Apply(MyFunc);
    };
};

However, since LeGo version 2.2 there is an even more pleasant method to do this:

1
2
3
4

func void Example1()
{
    FF_ApplyOnce(MyFunc);
};

Calling delayed function

Create a function, that is called once after 3 seconds.

1
2
3
4
5
6

func void Example2()
{
    FF_ApplyExt(MyFunc2, 3000, 1); // 3000 ms = 3 s, this function is called only once
};

func void MyFunc2() {};

There is also a Once variant of this function, that prevents adding it twice into the frame function list.

1
2
3
4

func void Example2()
{
    FF_ApplyOnceExt(MyFunc2, 3000, 1);
};

FrameFunction with Timer

Since LeGo 2.2, FrameFunctions package uses the Timer package, so it is possible to pause FrameFunctions at will:

1
2
3
4
5
6
7
8
9

func void Example3()
{
    FF_ApplyOnceExt(MyFunc3, 4000, 2);
};

func void MyFunc3()
{
    Timer_SetPaused(!Timer_GetPaused());
};
