我是Java的新手,所以这可能很容易解决,但是我想不出一种方法来重置画布中的积木。我正在使用函数redraw()

我尝试重新调用drawBricks
,但是我意识到现在我需要使数组起作用。
// brick layout
var bricks = [];
for(var c=0; c<brickColumnCount; c++) {
bricks[c] = [];
for(var r=0; r<brickRowCount; r++) {
bricks[c][r] = { x: 0, y: 0, status: 1 };
}
}
// draw bricks
function drawBricks() {
for(var c=0; c<brickColumnCount; c++) {
for(var r=0; r<brickRowCount; r++) {
if(bricks[c][r].status == 1) {
var brickX = (r*(brickWidth+brickPadding))+brickOffsetLeft;
var brickY = (c*(brickHeight+brickPadding))+brickOffsetTop;
bricks[c][r].x = brickX;
bricks[c][r].y = brickY;
ctx.beginPath();
ctx.rect(brickX, brickY, brickWidth, brickHeight);
ctx.fillStyle = "#0095DD";
ctx.fill();
ctx.closePath();
}
}
}
}
// redraw function -- used to reset when selecting mode
function redraw() {
score = 0
x = canvas.width/2;
y = canvas.height-30;
paddleX = (canvas.width-paddleWidth)/2
// find how to make bricks reappear
ctx.clearRect(0, 0, canvas.width, canvas.height);
drawBricks();
drawBall();
drawPaddle();
drawScore();
drawLives();
collisionDetection();
}
我希望砖块重新出现并完全重置游戏,但是目前它只是重置了球和桨。
答案 0 :(得分:0)
我认为您需要做这样的事情。
// brick layout
var bricks = [];
for(var c=0; c<brickColumnCount; c++) {
bricks[c] = [];
for(var r=0; r<brickRowCount; r++) {
bricks[c][r] = { x: 0, y: 0, status: 1 };
}
}
更改为
// brick layout
var bricks = [];
function resetBricks() {
for(var c=0; c<brickColumnCount; c++) {
bricks[c] = [];
for(var r=0; r<brickRowCount; r++) {
bricks[c][r] = { x: 0, y: 0, status: 1 };
}
}
}
resetBricks();
然后根据需要在代码中调用resetBricks()。
