It's possible to delay a function call by using a [wiki:Timer]. In fact it's even possible to delay a whole call including an object and several arguments. This is achievec by using an [wiki:Executor].

== Static functions ==
For static functions, use StaticTimer. A StaticTimer is created either in the constructor or by calling setTimer:
 * '''StaticTimer('''''interval, bLoop, executor''''')'''
 * '''setTimer('''''interval, bLoop, executor''''')'''
''interval'' is the time in seconds until the function gets executed.[[br]]
''bLoop'' is a bool. If set to true, the Timer will continue calling the function after every ''interval'' seconds.[[br]]
''executor'' is an ExecutorStatic of a static function

{{{
#include "tools/Timer.h"

void myFunction();
void myAdvancedFunction(int value);

// Call myFunctionafter 5 seconds
StaticTimer myTimer(5.0f, false, createExecutor(createFunctor(&myFunction)));

// Call myAdvancedFunction(10) after 3 seconds
ExectorStatic* executor = createExecutor(createFunctor(&myAdvancedFunction));
executor->setDefaultValue(0, 10.0f); // Bind the value
StaticTimer myAdvancedTimer(3.0f, false, executor);
}}}

See [wiki:Executor#DefaultValues this] for more information about how to find values.

== Member functions ==
For member functions you additionally have to add the object:
 * '''StaticTimer('''''interval, bLoop, object, executor''''')'''
 * '''setTimer('''''interval, bLoop, object, executor''''')'''
''interval'', ''bLoop'' and ''executor'' are like in StaticTimer (except executor has to be an ExecutorMember).[[br]]
''object'' the object on which to call the function.

{{{
#include "tools/Timer.h"

class MyClass
{
    void myFunction();
};

// Create an instance of MyClass:
MyClass* object = new MyClass();

// Call MyClass::myFunctionafter after 5 seconds
Timer myTimer(5.0f, false, object, createExecutor(createFunctor(&MyClass::myFunction)));
}}}
