Question

我有一个arduino项目，它使用二维数组来跟踪行/列信息。如果我尝试将行，列对分配给特定元素，则会出现错误：

expected primary-expression before '{' token

我可以毫无问题地分配单个值，但如果我尝试将第二个数组元素指定为整数对，则会出错。

example:
player[0][0] = 1;
player[0][1] = 2;  //this works
//but . . .
player[0] = {1,2};  //doesn't work



//here is more specific code from the project
// …. a bunch of code here declaring various global variables

int players[6][2];  //two dimensional array with 6 players each with a 2 value array (column and row)           
int score1;  //player 1 score
int score2;  //player2 score

//code here for setup/loop/etc.. Code calls the setPlayerPositions() function


void setPlayerPositions() 
{
    players[0] = {2,1};  //set the position of the ball (player[0]) to row 2, column 1
    players[1] = {1,4};  //set other player positions . . .
    players[2] = {2,4};  
    players[3] = {3,4};  
    players[4] = {2,6};  
    players[5] = {2,9};  
}

我已经把这个问题从桌子上砸了几次。

不幸的是，初始化数组时只能使用大括号表示法。初始化后，您必须单独处理每个数组元素。

arduino将值赋给多维数组
