Hi.

In AppGameKit v2 for insert or remove array elements we can use:



and for get array length we can use myArray.length.

But I have AppGameKit v1 and I need Insert and remove array element and track the size of array by variable.but I don't know how to do it.

Please Guide Me.

Thanks.

Thanks baxslash I understood

but for create bullet there is another way that we don't use insert or remove elemnts in array?

UPDATE: I think for do it should create User Data Type. can you give an bullet example with User Data Type that learn how can use it in Programming?

Thanks.

Yes, you could create an array upfront with enough slots to hold the max amount of bullets you require. And then just cycle through them all...

Like so (this is psuedo code, untested, and unlikely to work out the box... But should give you the idea...);



EDIT

Yes, Data Types would be a better solution, but in my opinion, more complex... I've only just started using Data Types myself, took me a while to work em out

EDIT2

In my example above, it is possible that the user could button bash fire more than 50 times before the first bullet gets a chance to be deleted... Easily resolved, but will let you work that out

This is what I am doing for bullets. Unless the bullets last for a long time the array doesn't have to be that large so it's not an issue. It gets slightly more complex if you want bullets to last for different amount of time as you develop 'bubbles' in the array which decreases you ability to shoot.
