Re: trying to solidify my understanding of coding concepts, and failing
Yes, this example is a good way to apply the concepts you learned about
handles. I'll make a example, let me know if you understood it, or if you became confused so I can explain it another way.
In this example, we'll create a function to play a random footstep. Why we'll use handles? Because if we use normal variables, each time we reference the footstep on the function, BGT will make a copy of the sound we referenced. And with a handle, you can prevent this copy and work with the original variable.
On the top of your script, you'd create a variable for each footstep:
sound step_1, step_2, step_3;
In your main function, you'll load each step sound separately, and in your move function, you could do something like this:
class player {
void move()
{
sound @step_sound;
int r;
// Generate a random number to select which step you want to play
r = random(1, 3);
if (r == 1)
@step_sound = @step_1;
else if (r == 2)
@step_sound = step_2;
else
@step_sound = @step_3;
step_sound.play(); // Equivalent to step_1.play() or the others, since the andle is a reference to the step chosen
}
Hope it helps a bit.
