CreateDynamicPolygon problem - zgintasz - 02.04.2012

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!

Re: CreateDynamicPolygon problem - TheArcher - 02.04.2012

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

Re: CreateDynamicPolygon problem - TheArcher - 02.04.2012

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);
    }
