我可以使用加速度計控制「鳥」,這是我的唯一問題,它可以在我的設備(手機/平板電腦)平坦時起作用,但是當您拿着它時不會閒置在你的手中玩。有沒有辦法將加速度計的零點偏移到y軸上的30°(度)?如何偏移加速度計lua corona sdk
display.setStatusBar (display.HiddenStatusBar);
system.setAccelerometerInterval(50);
system.setIdleTimer(false);
local background = display.newImage("bg.png")
--> GAME CHARACTER
local bird = display.newImage ("helicopter.png")
bird.x = 100;
bird.y = 100;
bird:setReferencePoint(display.CenterReferencePoint);
-- Speed of Movement with tilt. You can change it ans see the effects.
local tiltSpeed = 30;
local motionx = 0;
local motiony = 0;
local rotation = 0;
local function onTilt(event)
-- Its for the new position of the bird
motionx = tiltSpeed * event.xGravity;
motiony = tiltSpeed * event.yGravity;
end
local function moveBird (event)
bird.x = motionx + bird.x;
bird.y = bird.y - motiony;
bird.rotation = rotation;
end
Runtime:addEventListener("accelerometer", onTilt)
Runtime:addEventListener("enterFrame", moveBird)
如果你有event.zGravity那麼你可以簡單地旋轉,3D重力矢量任何你想要的位置。 – 2013-02-18 20:35:38
我將如何使用它? – 2013-02-18 21:43:34
更改爲-30 :) – 2013-02-19 19:42:29
