Can't parameterize a function

mimmi.ferrini · May 11, 2017, 1:06pm

Hello guys, it’s 3 months I’m developing an app with Corona Sdk and I’m almost there. Unfortunately, while working on the parameterization of a function I got some errors. Furthermore the timer.performwithdelay doesn’t seem to work since the powerup function I’ll post down there starts immediately. Did I parameterize in proper way? What could have I done wrong? Thank you in advance!

Which function are you talking about?

mimmi.ferrini · May 11, 2017, 3:22pm

I assume the problem is in the one called “powerup” but I’m not sure I parameterized in the right way

rob · May 11, 2017, 3:30pm

You’re running into one of the classic problems. Functions like timer.performWithDelay, transition.to, etc. all want an “address to the function to execute” when time comes. When you call a function with parameters:

powerup(0)

The function actually runs and returns a value, likely nil if you don’t have a “return” statement.

The result of this is that powerup(0) runs immediately and you are returning the value “true” so what you end up executing is:

timer.performWithDelay( 700, true )

To solve this you have to either not pass a value to powerup() and come up with some other method of letting powerup() what value it nees:

timer.performWithDelay(700, powerup ) -- note it's just the name of the function

Or what most people would do is use an anonymous function:

timer.performWithDelay( 700, function() &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; powerup(0); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;end )&nbsp;

This gets timer.performWithDelay an address of a function and when time comes it runs it, which calls your function with the parameters you want.

I’ll try this as soon as possible, thank you for advice!

mimmi.ferrini · May 11, 2017, 6:53pm

I’ve fixed the code (I didn’t actually need the “return true”) but now I get stack overflow. Dunno why but it seems to perform all the randomize stuff and things consequently without waiting for the delay. I still don’t get why. When my code was not parameterized it didn’t use to do that. However that’s the code:

You have a lot of recursion going on inside of powerup(). Recursion is functions that call themselves. Look at all of the times you call powerup() within powerup(). Lua allows recursion, but if you do it too much you will fill up the function call stack and get a stack overflow.

Rob

mimmi.ferrini · May 11, 2017, 7:10pm

I know, I meant to do like and it worked. The function has to be restarted after each goal (have to add that). The problem is that the powerup function is executed without waiting for the 700ms and I don’t get why. Here in console it shows thousands of prints in a fraction of 2 seconds and I don’t get why.

rob · May 11, 2017, 7:35pm

It’s because you’re still calling powerup() with a parameter instead of providing the address of the powerup function to timer.performWithDisplay. Those all need to be converted to Anonymous functions like I detailed above.

Rob

mimmi.ferrini · May 11, 2017, 7:50pm

So I ended up with this, which is obviously not parameterized but is slightly “more working” than previous code. Now the problem is that it doesn’t go further than 1st iteration.
