Question

I am developing an android game, i need some help regarding multi threading as i am considering it. I am attaching an image then i can explain what i need. enter image description here The bird is moving perfectly in my game from left to right and right to left, also moving her feathers as two images used, but i run the code at some time which will start to give egg, forexample bird will fly for 4 minutes and after every 20 seconds it will drop the egg, now egg will move from top to bottom, and what i think, another game thread will be used, i have used GameLoopThread object for it and SurfaceHolder holds the surface, I have used this code http://www.edu4java.com/androidgame/androidgame3.html I can make the condition of 20 seconds to give egg, but i am confused how to make a thread for an egg which will move from top to bottom and on other-side bird will be keep moving.

切实提前感谢。

你们只需要一只游戏,不使用两条,就会使事情变得更加复杂(需要协调所有事情)。

通常,游戏站采取下列步骤(并永远停靠):

handles key/touch event
performs the tick() (update of the sprites, states, etc)
renders the screen

因此,你需要做的是一份 sp(鸟类、蛋)清单。你们可以把他们放在一阵列。然后,你更新了他们各自的立场。

The sprite list will be dynamic, at the beginning of course you will have only one sprite, the bird. When the egg is created, just add it to the sprite array, so from that point on it will be handled as well.
