Arrays

Getting an array from Pawn code

For example, we have next native:

native SetNulls(array[], size = sizeof(array));

To use this array we should do next things:

define_native!(set_nulls, array_ptr: ref Cell, size: usize);

fn set_nulls(&self, amx: &AMX, array_ptr: &mut Cell, size: usize) {
    let array: &mut [u32] = get_array!(amx, array_ptr, size);
    
    for i in 0..array.len() {
        array[i] = 0;
    }
}

Pass an array to AMX stack

We have a public public GimmeArray(array[], size) to pass an array in the public you should do this:

fn some_function(&self, amx: &mut AMX) {
    let data = vec![0, 1, 2, 3, 4, 5];
    
    // use the raw function
    amx.push(array.len());
    let addr = amx.push_array(&data);
    amx.exec(index);
    amx.release(addr);

    // or use `exec_public` macro
    exec_public!(amx, "GimmeArray"; data => array, data.len());
