我正在开发一个游戏,其中不同的位图在屏幕上运行(SurfaceView)。由于速度不同,有时会出现两个字符叠加在一起的情况。我使用了OnTouch功能来捕捉玩家触摸角色的时刻。然而,当两个角色叠加时,我总是“触摸”后面的那个角色,我从来不碰他面前的另一个角色。为什么?我如何改变这种行为?由于我碰到前面的人,所以我总是碰到后面的人,真的很烦人。我希望问题很清楚。OnTouch位图覆盖
谢谢!
编辑:这是我的onTouchEvent功能:
@Override
public boolean onTouchEvent(MotionEvent event){
synchronized (getHolder()) {
boolean chibi_toccato = false;
if (!blocco_tocco){
//这里我有含有chibis结构(载体)中显示
for (int i = (mChibiVector.size() - 1); i >= 0; i--) {
Chibi chibi = mChibiVector.elementAt(i);
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (!chibi_toccato){
//触摸是一个标志,该标志告诉如果一个赤壁之前被触摸
if (chibi.touched) {
//如果我碰上船位图(scre上某处EN)的赤壁将是安全的
int navexend = posiz_nave_x + thread.mNave.getWidth();
int naveyend = posiz_nave_y + thread.mNave.getHeight();
if ((int) event.getX() >= posiz_nave_x &&
(int) event.getX() <= navexend &&
(int) event.getY() >= posiz_nave_y &&
(int) event.getY() <= naveyend){
chibi.chibisalvo = true;
thread.calcola_vel_x(chibi);
thread.calcola_vel_y(chibi);
} else {
chibi.touched = false;
int temp_chibi_y = chibi.getCoordinate().getY();
chibi.getCoordinate().setY(
temp_chibi_y +
chibi.getBitmapDimensions()[1]);
}
chibi_toccato = true;
} else {
// Here I check if a chibi is touched:
chibi = thread.checkTouched(chibi, (int) event.getX(),
(int) event.getY());
if (chibi.touched){
// If the chibi is touched, I save the X-Y info:
chibi.getCoordinate().setTouchedX((int) event.getX());
chibi.getCoordinate().setTouchedY((int) event.getY());
int temp_chibi_y = chibi.getCoordinate().getY();
chibi.getCoordinate().setY(
temp_chibi_y -
chibi.getBitmapDimensions()[1]);
chibi_toccato = true;
}
}
}
} else if (event.getAction() == MotionEvent.ACTION_UP) {
if (chibi.touched){
chibi_toccato = false;
int navexend = posiz_nave_x + thread.mNave.getWidth();
int naveyend = posiz_nave_y + thread.mNave.getHeight();
if ((int) event.getX() >= posiz_nave_x &&
(int) event.getX() <= navexend &&
(int) event.getY() >= posiz_nave_y &&
(int) event.getY() <= naveyend){
chibi.chibisalvo = true;
thread.calcola_vel_x(chibi);
thread.calcola_vel_y(chibi);
}
}
}
}
}
}
return true;
}
请提供您确定正在触摸的角色的代码片段。很明显,错误在那里,没有看到它很难猜出答案。 – 2011-04-03 17:34:30
