[Resolvido] matrizes duvida

Recommended Posts

estou começando meu jogo Earth Dragon e vou meter matrizes que vai ser o mundo (terreno).

eu não sei como vou fazer isso!

tipo matriz de 10,5:

0,0,0,0,2,0,0,0,0,0

0,0,0,0,2,0,0,0,0,0

0,0,01,1,0,0,0,0,1

0,0,1,1,1,1,0,0,1,1

1,1,1,3,1,1,1,1,1,1

qual é o 0,0 será qual destes?

0,0,0,0,2,0,0,0,0,0

0,0,0,0,2,0,0,0,0,0

0,0,01,1,0,0,0,0,1

0,0,1,1,1,1,0,0,1,1

1,1,1,3,1,1,1,1,1,1

eu confundime por causa de um jogo que fiz antes e começava onde esta o vermelho '-'

será que criei mal a matriz?

int mapa[100][30]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1,0,

minha matriz desse jogo que me confundi!

será que está mal?

onde começa o 0,0?

outra duvida:

int[10][5];

0,0,0,0,2,0,0,0,0,0

0,0,0,0,2,0,0,0,0,0

0,0,01,1,0,0,0,0,1

0,0,1,1,1,1,0,0,1,1

1,1,1,3,1,1,1,1,1,1

eu penso que 10 é o x ou seja em cada linha quantos elementos há. e o 5 é o y ou seja quantas linhas.

ajudem-me :/

agradecimentos,seuqram.

é normal começar no canto superior esquerdo pela simples razão que num array bidemensional podes ter uma linha (ou coluna) toda contigua.

ou então tenta criar uma função que te retorna a posição de memória do elemento na posição (x, y) dessa forma não interessa como tens codificado (seja de cima para baixo, da esquerda para a direita) que acedes sempre à posição correcta

Eu costumo aceder a arrays que reflectem um plano com indices chamados 'row' e 'col'.

O row é o primeiro indice; o col o segundo

for (row = 0; row < 12; row++) {              /* 12 linhas */
   for (col = 0; col < 79; col++) {          /* de 79 colunas cada */
       putchar(array[row][col]);
   }
   putchar('\n');
}

Respondendo a tua pergunta: o [0][0] é o primeiro elemento, o que pintaste a verde.

What have you tried?

Na tua matriz, a posição 0,0 é o primeiro elemento que declaras...

Agora, partindo do princípio que usas OpenGL ou similar, as coordenadas dependem de onde coloques o teu eixo. Tanto podes colocar o eixo em qualquer vértice, como o podes colocar no centro, ou mesmo noutra posição.

De qualquer forma se quiseres usar uma forma matriz[x][y], então o teu eixo é:

------------------------------------------->y

Eu costumo aceder a arrays que reflectem um plano com indices chamados 'row' e 'col'.

O row é o primeiro indice; o col o segundo

for (row = 0; row < 12; row++) {			  /* 12 linhas */
for (col = 0; col < 79; col++) {		  /* de 79 colunas cada */
	putchar(array[row][col]);
}
putchar('\n');
}

Respondendo a tua pergunta: o [0][0] é o primeiro elemento, o que pintaste a verde.

entao o row é o nomero de linhas, é isso?! não sei o que me correu mal naquele dia, obrigado xD

entao o row é o nomero de linhas, é isso?! não sei o que me correu mal naquele dia, obrigado xD

Obviamente que podes interpretar os dados de outra forma, mas vais estar a lutar contra a forma natural dos arrays.

Se fizeres o primeiro indice a corresponder a linhas e o segundo a colunas, todo o tratamento de dados flui mais naturalmente.

What have you tried?
