The idea of this rather simple game comes from "Astrostorm", which I beheld first on an Apple IIe nearly 40 years back!
Lazy game program. Just press spacebar to start or stop your spaceship. Beware: the response could be a bit late. Work your way toward the top of the screen. The game ends if your spaceship is bashed by an asteroid.

Ah, the good old days. I'd be the richest man in the world if my two great life plans ever come together.
Plan #1: Build a time machine with a range to 1970.
Plan #2: Code a pong game.
Now the good news is, I'm half way there. That's right, I built the time machine. Now all I have to do if figure out how to code a pong game???

I read a book which was a half-opinionated story of the history of Atari up to and including the creation of their awesomesauce 2600 machine. It seems a lot of energy was needed just to create that "Pong" game which wasn't a big deal.
I have to dig deep into my archives but I created four different programs of silly pong games in text mode in QuickBASIC. Then in QB64 I cobbled them up into one program with a menu to choose one of the games to play. One of the variations has the ball "explode" after it hits the target, and the fragments could also hit targets for additional points. It wasn't very interesting, I was very bored the day I created it.
In addition I was motivated by that famous book of games by David Heiserman I think was his name, for IBM PC. I believe there was an edition for TRS-80 computers but not necessarily for the Color Computer. One called "Arrow Shoot" which was very funny. I created a fancy version in Freebasic with four levels. It would be easy to convert it to QB64.
"A large tree fell on your head, and you're dead! Dead, dead, dead! You took 1 step. You collected zero treasures."
Nobody wanted to play an "adventure" game in which that was always the message!
Also the "Hacker's Aid" was one of my favorite programs. Not so good: the "translators". There's one that teaches somebody to talk like Bugs Bunny LOL.
Under 50 bucks! 50 bucks? The fun is back, oh yes sirree! It's the twenty-six hundred from Ah-tah-ree!

The guy who invented Pong Ralph Baer did so in the 1950's but shelved it. Unfortunately he sold out to Magnavox who turned Ralph's 'Brown Box' into the Magnavox Odyssey. Nolan Bushnell saw the pong game at a sales convention, where Bushnell impersonated a Magnavox salesman. So, as the saying goes, "Good artists borrow, great artists steal."

Same page Pete. 
I have the same ambition. I found this excellent tutorial on Pong with Vectors in YouTube, and also have been learning Vectors from Sprezzo. I also wanted to share this thing I made that does not use vectors, but it's pretty fun! I used the approach of a matrix of 3x3 cells to determine collisions. Turn your speakers on and at a low volume (it uses PLAY MB for sound effects, and the feedback is necessary). I almost had it perfect, and I think I could add one more permutation in my 3x3 matrix collision handler to get it so that the single brick in certain conditions isn't erased. Anyway, sharing is caring
YouTube Playlist: Godot Pong with Vectors Tutorial Series
Here is a video of the thing running: BOUNCER demo
Steve: I MergeFile'd this thing FYI useful for sharing inline in forum pastes!
I made this thing:
Code: (Select All) ''
' BOUNCER
'
' A little sandbox prototype to help me master the logic and physics for
' ball and paddle stuff. Mostly figuring out collisions and reflections.
'
' Press F5 to start the debugger. This is something that will also wind up
' going into my QB64_GJ_LIB for sure. Also a bunch of the _MISC.BM funcs
' and subs will be added too.

I have question about this line of code :
Code: (Select All) IF _KEYDOWN(32) = 0 AND holdspace THEN holdspace = 0
what exactly mean holdspace then ?
Is that mean holdspace > 0 or holdspace <> 0 ?

This was part of failed logic so the program reacts when the user expects. That is,
do not move the spaceship!
if the spacebar is never pressed. But do move the spaceship as soon as the user presses the spacebar.
No need to hold the key, thought. Press it again so the spaceship stops moving.
Otherwise people could become irritated with key-repeat intruding or something else. Holding the spacebar to move the spaceship would have made better sense otherwise. Also it would have been harder to reward a player who touches as less as possible LOL.
The response is actually late. I was trying to demonstrate something discussed sometime before. In a game that is payware the response has to be immediate or it won't catch on. I should try to convert the "Wormer" program (in "other BASICs" forum) to QB64 so people could try it and I could demonstrate my point better. Even in a little arcade game like this one, people won't play if the program is late responding to keypresses. This works in music also, need to respond right when the musician touches a key on the music keyboard, or the drum sounds when it's hit with the stick. If it's late it's no good and rejected.

i am asking you what mean just holdspace without expression
is :
1 .holdspace > 0
or
2 .holdspace <> 0
or something like
holdspace = 1
