问题描述

我已经搜索了所有论坛的赌注，但从未找到满足我问题的答案.

i've searched all the forum bet never found any answer satisfy my question.

我想为Nokia Asha 303创建一个横向的游戏，有什么方法可以将游戏画布旋转90度，从而使横向变为横向?因为我看了这部影片愤怒的小鸟阿莎303 .该游戏具有横向效果，因此我很好奇如何在j2me中做到这一点.

推荐答案

从MIDP 2.0开始，我们可以使用Sprite将图像旋转90度.我们需要的第一件事是正确大小的图像.以下代码可能在扩展Canvas的类的构造函数中-考虑Sprite和Image属性:

Since MIDP 2.0 we can use an Sprite to rotate an image in 90 degrees. First thing we need is an Image of the correct size. Following code could be inside the constructor of a class that extends Canvas - considering an Sprite and an Image attributes:

    int width = Math.max(super.getWidth(), super.getHeight());
    int height = Math.min(super.getWidth(), super.getHeight());
    screen = Image.createImage(width, height);
    sprite = new Sprite(screen);
    if (super.getWidth() < super.getHeight()) { // portrait screen
        sprite.setTransform(Sprite.TRANS_ROT90);
        sprite.setPosition(0, 0);
    }

在绘画内容时，请使用可变的图像图形"，然后使用波纹管之类的图像更新精灵.

When painting your content use the mutable Image Graphics, then update the sprite with the image like bellow.

    protected void paint(Graphics g1) {
        Graphics g = screen.getGraphics();
        // ... do your drawing
        this.sprite.setImage(screen, screen.getWidth(), screen.getHeight());
        sprite.paint(g1);
    }

如何使用手机显示屏上的最大面积?
.不要在画布上设置标题
.不要将Command添加到Canvas
.在调用super.getWidth()和super.getHeight()之前，请调用setFullScreenMode(true).

How can you use the biggest possible area on the handset display?
. Do not setTitle on your Canvas
. Do not addCommand to your Canvas
. Call setFullScreenMode(true) before calling super.getWidth() and super.getHeight()
