The bottom post is the code for a world that starts with a gun, and adds a random number of birds to it every 40 seconds. The top post is the code for the Bird class, which moves the birds across the screen toward the right, checking for collisions and (right) edge of world. Also, if four birds make it across the screen, the game ends. I noticed one more problem with the counting of birds making it across the screen. The count variable has to be a 'class' variable, not an 'instance object' variable. As an instance object variable, each bird that makes it across the screen will increment

I updated the demo linked on my previous post. It has two movement methods: a 4-way movement and an 8-way movement method. I have two views: one with dots (4 or 8, depending on which method is being used) to guide the actor and the other with shapes and lines, where you can adjust the thickness of the lines. Also, you can change the 'hand' that the actor uses to guide along the edge of the background color. I added bars (from my Bar class), three for switches and two for adjustable values for the thicknesses of the lines.

Edit: I saw only your first post, thx

k thx

There is some information here.

Ahhhh, yeah thanks guys

if (getWorld() != null) { ...

thx this helped :)

right ill give it ago . ^_^

That is something that would have to be done in the act() method of the world (using a counter initialized to the number of frames before a spawning). You will probably need an int to count the spawns also (initialized to zero). Each act cycle, do the following if the number of spawned actors is less then the total number of spawnings required { decrement the frame counter if frame counter is zero { spawn an actor increment spawn counter reset frame counter } }

Thank you sooo much!
