Im trying to assign a value to a mineral that is spawned by destroying an asteroid, and iv had a look at the old AUM examples but i just cant get it to work, the code that im using looks like this:

//////////////////
ENTITY* temp_ptr;

var minerals[1000];
var mineral_index = 0;
//////////////////

action green_crystal()
{
minerals[mineral_index] = handle(my);
mineral_index +=1;

///other code//////////

///////////////////////
function moveG(number)
{
temp_ptr =ptr_for_handle(minerals[number])
temp_ptr.y +=50;
}

but when I call it while playing with ex. moveG(1);
nothing happens, I know that the AUM examples are for A6 so the problems are probably because of that, and iv been searching the forums for a few hours without finding anything that can help me.


Would really appreciate some help with this.
Thanks

C_script
first: temp_ptr =ptr_for_handle(minerals[number])
is missing an " ; "

What this actually does is storing a handle of the mineral
or whatever is running the action to an array.

Later in the moveG function, a pointer is restored from
the array, given an indexnumber.

So the first thing you need to check, is weater the
action gets called (meaning, if an entity is beeing
"stored" in the array.
So watch the minera_index counter, or some other
indicator that this part works.

Then check if the move_g function is beeing called, AFTER the
array was filled with pointers.

If you dont have a nullpointer error, then some entity
is beeing moved (maybe not the mineral you where looking at)

Also the first entry is 0 and not 1
(for 1 you need to have at least two minerals referenced)

Also include some savety features, (like:

if(number>=mineral_index) return;
)

Especially when working with dynamically used arrays and pointers.

Okey, in the code i'm not missing the ; - just missed it when I wrote this

and I checked the index value and it adds one every time a new green mineral is created.

But what I didn't perhaps mention is that i want this to work in C-lite and not C-script as i'm using A7.

I tried calling a few of them after I had 9 minerals (index = 9)
with moveG(3) and moveG(5) but no dice.

But what is a nullpoint error? and how do I know if I got me one of those?

thanks for the help

with nullpointer error, i mean, that the
retrieved pointer (the entity) is null,
so basically you got an empty reference back.
This happens when you did not "insert" an entity (handle)
to the array at the given position, or the entiy was destoyed
meanwhile.

But the engine should complain when trying to manipulate this
empty entity then.

Okey, well I don't get any trouble from the engine.

This is all the code that's involved:
(I changed some of the names)

After I start it up I wait until I have some minerals and then I press tab and type: move_entity(3)
but none of the little buggers get removed.

Better us a functioncall using an keypress ingame.
I would not trust that manual debug typing of functions.

(or call automatically is after waiting some time in the mainfunction)

If it still not works, try to call the removal directly
within the entities action using the used indexnumber, then all entities should
be killed right away.

Capital!
It works when I assign it to a key, so I know it works, but still no go when I try to type it in :S any guesses why?

Anyhow from now on ill make sure to only try to call my functions from keys when testing


I tip my hat at you sir!

no problem.
I never used that debuginput, and would not trust it anyhow.
