Great job !
Probably, the best basic breakout ever.
Have a nice day.

bplus · « **Reply #2 on:** March 25, 2019, 11:46:26 am »

Very interesting variations from what I have played and coded.

Usually there is a solid wall of blocks with each layer up a color with a point value.
Here the block state is assigned by RND, 0 or 1 (present or not), I've not seen that before.

The ball approaches paddle at same basic angle but velocity depends on where ball hits paddle.
I wonder if there are blocks unreachable because the angle is so restricted?

Nice job. You can never go wrong with a nice breakout game. Well done.

SldBasic had a nice sub for displaying text at a given pixel height. I think I will try to duplicate, Rotozoom is overkill.

EDIT: I have updated this code with a sim of SdlBasic's Text(x, y, height, text$) subroutine to get text at different sizes (and now color parameter.)

Nice conversion. I thought it was quite sneaky how, after I accumulated about 200 points, the bat (which looks like a long loaf of bread) turned into a hamburger bun... Cool

FellippeHeitor · « **Reply #6 on:** March 26, 2019, 09:34:03 am »

Cool, version bplus, thanks for sharing! Love the 3d blocks too!

@johnno56 it does indeed look like a loaf of bread :-)

bplus · « **Reply #7 on:** March 26, 2019, 10:12:15 am »

:D yep! Loaf of bread and hamburger bun! Ha! that paddle ain't half what it used to be when you hit the first red brick!
But I like how silver ball sinks into the bread a little before bouncing back out.

I have updated the code with a sim of SdlBasic's Text() routine that allows text to be sized. This is actually the toolbox routine I wanted to make before I got Rotozoom involved for rotations.

And instead of tracking dx, dy of ball, it tracks mouse position.
I have noticed when I play the game, that I am constantly moving the mouse outside the screen boundary getting the paddle stuck, so maybe by tracking mouse / paddle x, y on score board, will help warn the player.

Oh, I have to say, Fellippes random fill of blocks makes for a much more entertaining knock out of the remaining bricks!

It would be nice to have that aspect and still keep games fair for scoring between players which I think the original game was doing. I thought the game needed more paddle control so players could have a chance to direct where the ball goes after contact with paddle.

Since I can't stop tweaking this, here's the latest iteration of my breakout clone (I'm calling it Blockout for now):

- I've built in a particle system which allows for some cool visual additions.
- Three types of blocks: regular, hit twice and unbreakable.
- Power-ups: you get a Fireball (allows destroying "hit twice" blocks at once), Shooter, Magnetic paddle, Breakthrough, Stretch Paddle.
- Power-ups show up when you destroy certain blocks. You must catch them to activate them.

I thought the game needed more paddle control so players could have a chance to direct where the ball goes after contact with paddle.

I hope you'll enjoy the magnetic paddle power-up I've added.

Wow! marvelous variations Fellippe.

FellippeHeitor · « **Reply #14 on:** March 26, 2019, 01:24:42 pm »

Thanks! I had never actually played the original game and I cut my teeth on the format with a game called DXBall, back in Windows 98 days. That's where the inspiration for this one comes from.
