Hi guys,

I'm using this streamer and I need help:
https://sampforum.blast.hk/showthread.php?tid=102865

I want to create areas with CreateDynamicPolygon function. Here is my script:

Code:

new
	Float:vertexai[ ][ ] =
	{
	    // coords
		{-3264.850341, 1881.825683,
		-3298.238769, -3066.096191,
		760.000000, -2860.000000,
		-52.000000, -1894.000000,
		 24.250000, -1634.015625,
		 65.000000, -1411.092285,
		 33.000000, -1249.550781,
		107.000000, -1158.429687,
		 47.000000, -1098.135498,
		102.000000, -920.469970,
		-57.000000, -902.997314,
		-124.000000, -857.887939,
		-181.000000, -784.712402,
		-293.000000, -350.712402,
		-776.000000, -323.554443,
		-1042.000000, -318.570068,
		-1009.000000, 265.434570,
		-841.000000, 461.434570,
		-1058.078125, 670.094238,
		-1561.000000, 1582.991821,
		-3264.850341, 1881.825683
		},
		// another coords
		{ -2264.850341, 881.825683,
		-2298.238769, -2066.096191,
		760.000000, -1860.000000,
		-52.000000, -894.000000,
		-2264.850341, 881.825683
		}
	}
;
// Loading:

	new
	    polygons[ 2 ]
	;
	for( new i; i < sizeof( vertexai ); i++ )
	{
		polygons[ i ] = CreateDynamicPolygon( vertexai[ i ] );
	}

But I get this warning:
warning 224: indeterminate array size in "sizeof" expression (symbol "maxpoints")

How to solve that?
Thank you very much!

Well sizeof returns the size in elements of an array. vertexai has 2D array form so it doesn't know what array to extract.

Example of usage:

pawn Code:

new test[4];
for( new i; i < sizeof( test); i++ ) { printf(" %d ", test); }

it unpacks "4".

2D

pawn Code:

new
    test[5][10];
printf("%d %d", sizeof (test), sizeof (test[]));

Thanks for your reply, but I don't understand what I have to do... Can you give me a solved code?
I replaced
polygons[ i ] = CreateDynamicPolygon( vertexai[ i ] );
with
polygons[ i ] = CreateDynamicPolygon( vertexai[ i ][ ] );
but then I get this error :/ : error 029: invalid expression, assumed zero

well i've tried to do in this way quickly

pawn Code:

#define points_size (26+1)// i tried to do it manualy beacuse the array has known array size
    new Float:vertexai[ ][ ] =
    {
        // coords
        {-3264.850341, 1881.825683,
        -3298.238769, -3066.096191,
        760.000000, -2860.000000,
        -52.000000, -1894.000000,
         24.250000, -1634.015625,
         65.000000, -1411.092285,
         33.000000, -1249.550781,
        107.000000, -1158.429687,
         47.000000, -1098.135498,

        -3264.850341, 1881.825683
        },
        // another coords
        { -2264.850341, 881.825683,
        -2298.238769, -2066.096191,
        760.000000, -1860.000000,
        -52.000000, -894.000000,
        -2264.850341, 881.825683
        }
    };
// Loading:

    new
        polygons[ 2 ]
    ;

    for( new i; i < sizeof(vertexai); i++ )
    {
        polygons[ i ] = CreateDynamicPolygon(vertexai [ i ], vertexai[ i ][0], vertexai[ i ][1], points_size);
    }
