zu compilieren , dann erhalte ich folgende Fehlernachricht

Der Compiler schrieb:

obwohl uint8 nur ein Typ unsigned int mit 8 bit ist (mit int funktioniert es auch nicht) Was habe ich falsch gemacht ?

is ein struct size16 mit 4 zweidimensionalen array für farbinformationen

Poste doch mal ein vollständiges Minimalbeispiel.

Gruß Caipi

struct material {
	uint8 size_of;
	uint8 priority;
	bool lightened;
	struct size16 {
		 uint8 alphamap[16][16];
		 uint8 depthmap[16][16];
		uint16 colormap[16][16];
		 uint8 shinemap[16][16];	};
	struct size32 {
		 uint8 alphamap[32][32];
		 uint8 depthmap[32][32];
		uint16 colormap[32][32];
		 uint8 shinemap[32][32];	};
	struct size64 {
		 uint8 alphamap[64][64];
		 uint8 depthmap[64][64];
		uint16 colormap[64][64];
		 uint8 shinemap[64][64];	};
	};

Der Struct

void encode_material(/*sources*/material source , uint8 material_size , uint8 priority , bool light_culled , uint8 alpha_source[] , uint8 depth_source[] , uint16 color_source[] , uint8 shine_source[] ) {
			source.lightened = light_culled;
			source.priority  = priority;
			source.size_of	 = material_size;
			switch (material_size) {
				case 16:
					for (uint8 i = 1; i <= material_size ; i++){
					for (uint8 j = 1; j <= material_size ; j++){
					source.size16.alphamap[i][j] = alpha_source[i][j];
					source.size16.depthmap[i][j] = depth_source[i][j];
					source.size16.colormap[i][j] = color_source[i][j];
					source.size16.shinemap[i][j] = shine_source[i][j];
					}
					}
					break;
				case 32:
					for (uint8 i = 1; i <= material_size ; i++){
					for (uint8 j = 1; j <= material_size ; j++){
					source.size32.alphamap[i][j] = alpha_source[i][j];
					source.size32.depthmap[i][j] = depth_source[i][j];
					source.size32.colormap[i][j] = color_source[i][j];
					source.size32.shinemap[i][j] = shine_source[i][j];
					}
					}
					break;
				case 64:
					for (uint8 i = 1; i <= material_size ; i++){
					for (uint8 j = 1; j <= material_size ; j++){
					source.size64.alphamap[i][j] = alpha_source[i][j];
					source.size64.depthmap[i][j] = depth_source[i][j];

					source.size64.shinemap[i][j] = shine_source[i][j];
					}
					}
					break;

			}

Die Funktion (Recht langer Funktionskopf )

struct material {
  struct size16 {
    /* ... */
  };
  size16 size16_elem;
};

(btw ist es Verschwendung, dort drei structs zu definieren, wenn sowieso nur eins davon gleichzeitig genutzt wird)

Ich brauche statiche Werte für die Arrays , deswegen habe ich 16 32 und 64 gewählt ; ich habs auch schon mit ner Klasse versucht , aber habs net auf die reihe bekommen ...

Oder haperts am Englischen? ohne Englisch wirds schwer!

PS: Wusst net , was bounds sind

PS: eventuell kannst du statt der fixierten struct's auch solche dynamisch angelegten Felder verwenden - wenn nicht, würde ich eigentlich mit einem Doppelarray auskommen (und ungenutzte Felder leer lassen).
