i create the array like this:

NumOfConditions = 1;
NumOfDialogs = 1;

for(int i=0;i<NumOfConditions;i++)
{
  conditions<i> = new int[2];
}

conditions[0][0] = ALWAYS;
conditions[0][1] = 0;

ALWAYS is defined as 0

then when i got to retrieve the value

textprintf_ex(screen, font, 150, 220, makecol(255, 255, 255), -1, "conditions: %d", conditions[0][0]);

i get values like 4042624

any ideas what im doing wrong?

edit:: i figured out that its giving me the memory address... so how do i get the value instead?

How are you defining conditions?

ummm, if your refering to ALWAYS then like this

#define ALWAYS 0

No, I'm talking about your multi-dimensional array called "conditions".

I think you should do it like this:

int *conditions;

conditions = new int[NumOfConditions];

for(int i=0;i<NumOfConditions;i++)
{
  conditions<i> = new int[2];
}

And then get rid of it with delete [] conditions;I'm not 100% sure, since I haven't really worked with dynamic arrays in C++ that much (and especially not with multidimensional ones). But try it and see for yourself.

Do you have something like this somewhere in your code?int **conditions;If no then how do you define/declare the contitions variable?

that could be it.. i was using

int* conditions[];

EDIT:: i change

int* conditions[];

to:

int** conditions;

without changing anything else it crashes at runtime.

if i change

int* conditions[];

to:

int* conditions;

and add:

conditions = new int[NumOfConditions];

i get compile time errors about converting an int* to int

...

so far i still havent found the solution.

int* conditions[];
should be the same as int **conditions;
I don't know why your code isn't working, though

for(int i=0;i<NumOfConditions;i++)
{
  conditions<i> = new int[2];
}

conditions[0][0] = ALWAYS;
conditions[0][1] = 0;

Should be:

for(int i=0;i<NumOfConditions;i++)
{
  conditions<i> = new int[2];
  
  conditions<i>[0] = ALWAYS;
  conditions<i>[1] = 0;
}

And yes, you must do delete [] conditions[i]; as well as delete [] conditions;
Lots of [] symbols.

Its kind of scary because delete conditions[i]; will compile and might even run ok. But eventually the memory corruption will catch up with you and then you're really screwed.

[edit]

It could be that it detected your error of using delete when you should be using delete [] and switched it for you. But a pointer to a pointer and theres no way for it to know it should switch.

Do you have conditions = new int[NumOfConditions];in your code? If you are having random values then I would guess you don't have.

Hope this helps! I remember being stuck on this once....

Things to watch for: the array 'conditions' is an array of POINTERS TO POINTERS, thus the **

To delete the array properly you have to delete all the last dimension elements first and then back to the first. (that's what the for loop is at the end)

Edit: Forgot the 'define'...

EDIT:

Edit:

ok well i got it to work using vectors and also using the code Matt Weir posted. But it still crashes at this line:

if(worldconditions[j] == conditions<i>[0])

worldconditions[j] i checked right before the if statement and its equal to 0 which is also what conditions<i>[0] is... but it doesnt make it to the next line.

here is the code that has the error (the whole file)

I don't have much time at the mo but I suspect the value of 'raylength' isn't quite right. You might be trying to look at an invalid index in you 'conditions' array. Make the program print out the values of i & j before the 'if' statement and check the last values before the program crashes.

Matt.

ok, after a few little ajustments the crash point has moved to this line

textprintf_ex(screen, font, 150, 160, makecol(255, 255, 255), -1, "test: %s", dialogs->at(conditions[0][1]).c_str());

(i changed the i to a 0 to make sure that wasnt the problem but it still dies)

EDIT:: i found my problem i was int the for loop i was going from the max value of the array and going down through the array (if it had one member i was starting at 1) but if there was only one member (like in this case) the element would be at location 0 not 1!
