Im am working on some code and a little problem arose, after getting annoyed and my teacher not being able to solve the problem i finally found in the manual that functions create their very own variables and cannot affect global ones. So if I want a function to return 7 variables to an array, is it impossible?

No, it won't return seven variables from a function. However, you can simply change the value of the arrays inside a function. This effectively works around the fact that you cannot use global variables with DBC. An example:


Hope this helps,

I thought that you couldnt even edit array values, since that is how it works with normal variables, thanks

You can't assign values to an array during declaration.

dim objects(100,7)
objects(100,7)=0

...though in DBC, numeric arrays automatically contain zero when they are declared, so implicitly stating it is not necessary.

Tutorial 1 covers arrays and number 6 covers functions here:

Check the counting values of objectN used in the For..Next loop. If you don't have a For..Next loop then check whatever value objectN is at this point in your program.

it isnt a for next loop, its part of the function,objectN is the object number.

But i have it working now. Thanks
