In this test code:
@Override
public void render() {
test();
}
private void test() {
}
How can I call test(); one time (NOT loop) ?
One way is simple flag. Just create a boolean that will tell you if test() was called
boolean isTestCalled = false;
private void test()
{
System.out.println("test!");
}
@Override
public void render(float delta)
{
if( !isTestCalled )
{
isTestCalled = true;
test();
}
...
you can change boolean to int and increase it every time you will call test() to limit test call count. I don't very like flags - it generates spaghetti code.
If it would be C++ the second option would be using static variable inside test function and just tell it how many times it should be called - but hey this is Java :). Statics are only for classes but you still can simulate it:
//even inside your class
static class Counter
{
public static int count = 0;
}
private void test(int limit)
{
if( ++Counter.count <= limit ) //here you can add something like ...&& limit > 0 to have and option to infinite calls when calling test(-1) for example
{
System.out.println("test!");
}
}
@Override
public void render(float delta)
{
test(2);
...
And last but not least - in case you want to call test() exactly on a start of render - just move it to the show() function. But I guess it is not what you want to do when you are creating a question like this.
