RE: FLASH: Cool Video Games

[Dunn, Jeff]

I have created a simple experiment to learn more about using variables for

my scrolling videogame background.  I created a movie clip with three frames

and called it circle.


Frame 1 behavior

Set Variable: "bkg" = 320


Frame 2 behavior

Set Property ("circle", X Position) = "bkg"


Frame 3 behavior

Set Variable: "bkg" = bkg + 1

Go to and Play (2)


I was hoping that this would put the circle at pixel 320 and gradually move

it to the right of the screen.  It does not.

I'm doing something wrong, but I'm not sure what.  Any comments or

suggestions are welcome.

Hi, Jeff.


I don't know how much response you've had to this thread, since I've been in

and out & just scanning stuff today, but am impressed with your start and

have some general suggestions/comments about how to structure this (just my

thoughts, mind you I'm no expert)


I would make the background a separate movie clip so you can tell target it

when to go and stop and reverse.  I would control it with a controller movie

clip, I think, where there is a "forward loop" and a "reverse loop" so that

your button action can call the controller mc frame action (reason you need

the controller is you want a continuous action, which takes 2 frames, and

you only have one frame in the button)  I don't think I'm explaining this

very well.


mcBack is instance name of the background movie clip, set up so that its

first and last frames have overlapping graphics so it appears to continue

forever...


mcControl is the instance name of the controller movie clip, which has 5

frames.  First frame label "park" action "tell target mcBack stop"

Second frame label "forward" action "tell target mcBack go to next frame"

Third frame action "go to and play (frame label) forward"

Fourth frame label "reverse" action "tell target mcBack go to previous

frame"

(you'll need an if statement somewhere here that says if _currentframe = 1

then go to final frame of your mcBack and vice versa for the forward motion)

Fifth frame "go to and play reverse"


Now, your button actions will be

forward button:  call mcControl:forward

back button:  Call mcControl:reverse

Stop:  Call mcControl:park


Now, within that mcBack MC you can create nested movie clips for your

characters.  They will each need an instance name so you can track their

position.  There's great info on collision detection on

http://www.moock.org/webdesign/flash/actionscript/collision/index.html


That was a quick run-through, pseudo-code and NOT checked for accuracy, was

just meant to head you in the (hopefully) right direction
