我正在开发一个在屏幕上运行不同位图的游戏(SurfaceView)。由于它们的速度不同,有时会出现两个字符叠加在一起的情况,一个接一个。我使用 OnTouch 功能来捕捉玩家触摸角色的瞬间。但是,当两个字符叠加时,我总是“触摸”后面的一个,我从不触摸他前面的另一个。为什么?我怎样才能改变这种行为?因为我在摸前面的,所以我总是摸后面的,真的很烦人。我希望问题很清楚。
谢谢!
编辑:这是我的 OnTouchEvent 函数:
@Override
public boolean onTouchEvent(MotionEvent event){
synchronized (getHolder()) {
boolean chibi_toccato = false;
if (!blocco_tocco){
// 这里我有包含要显示的 chibis 的结构(一个向量)
for (int i = (mChibiVector.size() - 1); i >= 0; i--) {
Chibi chibi = mChibiVector.elementAt(i);
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (!chibi_toccato){
//touched 是一个标志,表明之前是否触摸过赤壁
if (chibi.touched) {
// 如果我触摸船位图(屏幕上的某处),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;
