Hi to all;
I try to program " tetris game "
First i did the point about :
Cube Block falling to the floor and another one appear then falling also but my problem is whe cube block fall and there is another one the floor the falling mix with the one on the floor !!!
Although i make a conditon that prevent mixing.
from here http://www.mediafire.com/?khg2p2mlpxpixz6 you can download my code .
There is there package in package TetrisView There is class TetrisCell which have the problem in method moveBlockVerticle()();
you will fin dthis code in it for prevent mixing bloks :
if (tetrisBlockShapesEnum == tetrisBlockShapesEnum.CUBE_BLOCK && nextRow - 2 == blockData.getPoint().getX()
|| tetrisBlockShapesEnum == tetrisBlockShapesEnum.I_BOLCK && nextRow - 4 == blockData.getPoint().getX()) {
canDraw = false;
} else {
canDraw = true;
}

Spec-Driven Development inverts traditional architecture by making specifications executable and authoritative. It transforms declared intent into validated code through AI generation and provides architectural determinism. It eliminates drift through continuous enforcement, but demands new engineering discipline in schema design and contract-first reasoning.
