타일 기반 게임에서 중복 된 타일

Question

현재 Java2D를 사용하여 Java 기반 타일 기반 게임을하고 있습니다. 그러나, 나는 정말로 바보 같은 것을 놓치고 있다고 생각합니다. 또는 아마, 제가 수천 번 내 코드를 점검하고 이상한 것을 보지 못했을 것입니다.

그러나 모양은 다음과 같습니다 : 그래서 이것은 내 게임의 인쇄 바로 지금

글쎄, 내가 알고, 그것을 잘 보이지만 당신은 살펴 경우 내 타일 기반 수준의 이미지 :

(회색 타일, 녹색 타일 잔디 벽돌되어 있으며 갈색 타일 먼지입니다)

그래서 벽돌 타일이 이상한 방법으로 복제됩니다. 여기 레벨 코드는 다음과 같습니다.

Answer 1

(내 다른 대답은 (내 생각) 잘못되지해야 다시하는 이유를 생각 나게하지만이 특정 문제에 대답하지 않습니다 나중에 알 수있는 문제가 수정되었습니다.)

레벨 1.PNG에는 벽돌과 일치하지만 눈에 보이지 않는 RGB 값을 가진 비정상적인 픽셀이 있습니다. 투명성이있는 것 같지만, PNG에 대해서는 아무 것도 모른다. 어쨌든이 level1.png은 깨끗하고 정상적으로 작동합니다.

시간이 걸렸습니다. 나는 당신의 MCVE보다 최소한의 MCVE를 만들었습니다. 이 버전은 미래의 독자가 문제의 원래 png로 문제를 디버그하는 데 도움이 될 수 있습니다.

Answer 2

문제는 render 방법 안쪽이 덩어리에 있습니다

이 말하는 것 같다

for (int y = (int) Math.max(yOffset/(tileSize + scale), 0); y < Math.min((MCVE.HEIGHT + yOffset)/(tileSize + scale) + 1, levelImage.getHeight()); y++) { 
    for (int x = (int) Math.max(xOffset/(tileSize + scale), 0); x < Math.min((MCVE.WIDTH + xOffset)/(tileSize + scale) + 1, levelImage.getWidth()); x++) { 
     if (tile[x][y] != null) 
      screen.drawImage(tile[x][y], (int) (x * (tileSize + scale) - xOffset), (int) (y * (tileSize + scale) - yOffset), (tileSize + scale), (tileSize + scale), null); 
    } 
} 

: "내가 그리려는 픽셀 to, draw tiles "(그러나 나는 그것에 대해 잘못 될 수있다. 내가 for-loop guard를 읽을 때마다 나는 다른 설명을 얻는다). 문제는 도면 영역 측면에서 x와 y를 계산하는 것이지만 tiles[] 배열의 인덱스 측면에서 사용하는 것입니다. 당신은 "타일을 그릴 타일을 그릴"을 원합니다.

generateLevel()의 루프가 올바른 작업을 수행하고 있습니다. 그런 종류의 루프를 사용하십시오 (for (y = 0 y < levelImage.getHeight(); ++y)). yOffset, tileSize 및 scale에 대해 걱정할 필요가있는 유일한 코드 비트는 이 실제로 타일을 그립니다 코드입니다.

이 코드를 테스트 할 수 쓴, 왜 테스트를 작성해야합니다 :)
