i) 三角洲 时间使用。 我的法典如下:

public class Time {
    public static float deltaTime = 0;                      
    public static long frameCount = 0;                      
    public static float fixedTime = 0;                     
    public static float fixedDeltaTime = 0.1f;      
    public static float maxDeltaTime = 0.25f;

而现在,我主修(主修)的功用是:

 while (running) {
        canvas = null;
        try {
            canvas = this.surfaceHolder.lockCanvas();
            synchronized (surfaceHolder) {
                float newTime = System.nanoTime() / 1000000000.0f;
                Time.deltaTime = frameTime = newTime - currentTime;

                if(frameTime > Time.maxDeltaTime)
                        frameTime = Time.maxDeltaTime;

                currentTime = newTime;

                accumulator += frameTime;

                while(accumulator > Time.fixedDeltaTime)
                { 
                        this.gamePanel.update();   // where the player and my enemy gets updated                         
                        accumulator -= Time.fixedDeltaTime;
                iii

                this.gamePanel.render(canvas);
                //Perform all non-physics-related updates here


                ++Time.frameCount;

                framesSkipped = 0;  // resetting the frames skipped

                timeDiff = System.currentTimeMillis() - beginTime;
                // calculate sleep time
                sleepTime = (int)(FRAME_PERIOD - timeDiff);

                    if (sleepTime > 0) {
                            // if sleepTime > 0 we re OK
                            try {

                    iii

                            this.gamePanel.update(); // update without rendering
                            sleepTime += FRAME_PERIOD;  // add frame period to check if in next frame
                            framesSkipped++;
                    iii

                    if (framesSkipped > 0) {

in the gamePanel.update() ive got the update calls for the player and my enemy. Now my Problem is, that at the start of my game the deltaTime is extremly high und thus my movement is very fast, because i have the following in my enemy class in the update method:

                   x += vX * Time.deltaTime; // velocity * deltaTime
                   y -= vY * Time.deltaTime;
                   //Log.d(TAG, "Time:"+Time.deltaTime+" x: "+x+" y: "+y);
                   vY -= gravity;

Am i doing it right, or is something wrong with my structure? Thanks for any help.
