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
