使用此代码,我用单个棋盘bmpWhite
和bmpBlack
for (int i = 0; i < 7; i++) {
for (int j = 0; j < 7; j++) {
if (white == true) {
color[i][j] = 0;
white = false;
}
else {
color[i][j] = 1;
white = true;
}
}
}
}
public void onDraw(Canvas canvas)
{
if (gameViewWidth == 0)
{
gameViewWidth = theGameView.getWidth();
gameViewHeight = theGameView.getHeight();
}
for (int xx=0; xx < 7; xx++)
{
for (int yy=0; yy < 7; yy++)
{
int x_start=(yy * 23);
int y_start=(gameViewHeight / 2) + (yy * 12);
int xx1=x_start + (xx * 23);
int yy1=y_start - (xx * 12);
if (color[xx][yy] == 0)
{
canvas.drawBitmap(bmpWhite, xx1, yy1, null);
}
else if (color [xx][yy] == 1)
{
canvas.drawBitmap(bmpBlack, xx1, yy1, null);
}
}
}
输出应该是具有交替颜色的棋盘(8x8)。但输出是这样的:
如您所见,底部和顶部的最后两行是相同的颜色。 我做错了什么?
答案 0 :(得分:3)
for (int i = 0; i < 7; i++) {
for (int j = 0; j < 7; j++) {
if (white == true) {
color[i][j] = 0;
white = false;
}
else {
color[i][j] = 1;
white = true;
}
}
}
但它接缝你有8 * 8板。所以你必须写:
for (int i = 0; i < 8; i++) {
for (int j = 0; j < 8; j++) {
if (white) {
color[i][j] = 0;
white = false;
}
else {
color[i][j] = 1;
white = true;
}
}
}
以及代码的第二部分
答案 1 :(得分:1)
你的for循环只循环了6次。你从0开始是正确的,但是让它int i = 0; i < 7; i++
循环1。尝试将int i = 0; i <= 7; i++
或int i = 0; i < 8; i++
都设置为有效。
