[AS3]"Barrier function" Enough is Enough iam tired plz help me :(

programming flash

[COLOR=blue]Hello all , its been really long time i kept trying and trying to find an answer all over and i didn’t find any :S

and i posted here my question several times On one of the forums and no one answered except one gave me some files i will share it with you , but still i keep getting error over and over each time i try something

Then i Decided to end it One time and for all …

i decide to post the SAME Thread In Many Action-Script Fourms , by this way , i can find out My answer fast …

[COLOR=black][SIZE=6]so here is the deal :[/SIZE][/COLOR]

  1. i made a carMC MovieClip >>> inside this movie Clip i wrote all the AS Code for the car movement and speed
    **Work perfect with small bug ( i have to click on it first to activate it )

  2. i made a simple Black Square and and gave its Instance name buildings_mc
    and i wanted to make a function between those two to test “Hit” between them

    i) all i know about that is “hittestobject();” didnt work out and some dude told me it cant work with “hittestobject” and he gave me a Link for new stament “BitMapdata” “mikechambers.com/blog/2009/06/24/using-bitmapdata-hittest-for-collision-detection/” <— [COLOR=red]u add www[/COLOR]

    ii)i toke that link and i decided to try it out … it wasnt really teaching much because in the function name he keep writing 255 and i dont know what is it :S , anyway … i decided to edit it to my carMc and Buildings and made few changes and it [COLOR=green]Worked ![/COLOR]

the Current Problem is :—

what should i write to make the flash

1)not allowing Bitmapdata(carMC) to move on buildings_mc or under it

2)Record the Hit angle … and respond to the hit by reflecting it ( like real )

3)how to make the Machine able to move on display only not outside it
>>or how to make it inside a square and can’t leave it

if u can answer Even one of those i will be very thankful [/COLOR]
