tetris help

[25jai]

hey i'm doing tetris for my final summative project in computer science class, and i need lotsa help from u guys who can help me

first of all, when the blocks are coming down, in tetris you are allowed to rotate as many times as you want, move around, before it drops another block. my question is: how do you do this in turing?

i may have a lot more questions later on, but this would be my most important one rite now.

thnx in advance

yes i've seen your program, and your blocks do not do that.
your blocks do only one certain move per "drop"
but in real tetris, you can do multiple moves per drop
that's what i'm asking...

so, anyone wanna help me?

what you do is you make rotation independant of the fall. Basically take out his rotation code and place it in a loop of its own. Then you check for elapsed time every so oftern and compare it to the last time the piece was dropped a row + drop delay.

i read a thread by brightguy someone talking about clock, and i also saw one of my friend who's also doin tetris in class using the clock function
can anyone tell me how this works and how i can use this in my tetris program?

anyone?
plz i really need help

while what you do is check the time in secs at some point and save it in a var and then check it agean latter on in the progame and take the diffrence of the new one and the saved one and you get how much time has pased.

You could uses that to detrime whtere to move the block down or not.

EX.

if 10 secs gone by then

move block down

reset timer

end if

I looked through the source of my old Tetris program... it's not very pretty. I wrote most of it when I was just learning how to program. You'd probably be better off not looking at it.

You should store each cell's filled status in a boolean matrix. Also, here's the basic looping structures for the program:

code:

var cell : array 0 .. 9, 0 .. 19 of boolean var speed, timer, prevTime : int := 0 var key : string (1) loop      %choose random block      loop           key := " "           loop                if hasch then                     getch (key)                     %move block according to keypress                end if                clock (timer)                exit when timer > prevTime + speed           end loop           prevTime := timer           %move block down a square           %exit when block cannot move down anymore      end loop      %check for full line, add up score      %change level/speed if necessary end loop
