LUA-LÖ；VE 2D-精灵在击中盒子时死亡

--好的，基本上我已经在游戏中设置了我想要的一切。我现在要做的就是创造敌人。我已经设置了产卵和移动，但是当玩家击中敌人时，什么都不会发生。当红球击中障碍时，我希望客户关闭。（很明显，我会在以后更改，但这只是暂时的）如果你能编写代码在游戏中解释这一点，我将不胜感激。我不熟悉这种编程语言，只有15岁还在学习如何编写代码。我非常高兴在这场比赛中给你荣誉

谢谢你-奥利

这里有两种方法：

你可以做高级碰撞

你可以做简单的碰撞

第二种更简单，但第一种更适合这种游戏

第一种方法：

首先，您需要了解以下代码：

function circleAndRectangleOverlap( circleX, circleY, circleRadius, rectangleX, rectangleY, rectangleWidth, rectangleHeight )
    local distanceX = math.abs( circleX - rectangleX - rectangleWidth / 2 )
    local distanceY = math.abs( circleY - rectangleY - rectangleHeight / 2 )

    if distanceX > ( rectangleWidth / 2 + circleRadius ) or distanceY > ( rectangleHeight  /2 + circleRadius ) then
        return false
    elseif distanceX <= ( rectangleWidth / 2 ) or distanceY <= ( rectangleHeight / 2 ) then
        return true
    end

    return ( math.pow( distanceX - rectangleWidth / 2, 2 ) + math.pow( distanceY - rectangleHeight / 2, 2 ) ) <= math.pow( circleRadius, 2 )
end

function circleAndRectangleOverlap( circleX, circleY, circleRadius, rectangleX, rectangleY, rectangleWidth, rectangleHeight )
    local distanceX = math.abs( circleX - rectangleX - rectangleWidth / 2 )
    local distanceY = math.abs( circleY - rectangleY - rectangleHeight / 2 )

    if distanceX > ( rectangleWidth / 2 + circleRadius ) or distanceY > ( rectangleHeight  /2 + circleRadius ) then
        return false
    elseif distanceX <= ( rectangleWidth / 2 ) or distanceY <= ( rectangleHeight / 2 ) then
        return true
    end

    return ( math.pow( distanceX - rectangleWidth / 2, 2 ) + math.pow( distanceY - rectangleHeight / 2, 2 ) ) <= math.pow( circleRadius, 2 )
end
