    Default Why isn't my collision working?

    	private void checkForCollision() {
            for(int i = 0; i < world.arrayNum; i++){
    		if(world.isBlock[i] && playerRect.intersects(world.blocks[i])) {
    		xDirection(0);
                    yDirection(0);
                    System.out.println("HIT!");
     
    		}
            }
    	}

    I have this method constantly updated and everytime i do hit the block it does print out HIT but it never stops my player from moving into it. Do you see anything wrong?

    I see a method being overworked. "checkForCollision" in my book would return a boolean, and would not adjust xDirection and yDirection directly, but that is just a side issue I am certain.
    Without seeing how this method is actually being used, not much we can say about what is wrong with it.
    Use some printlns to find out what is happening when
