Space Invaders Programming (BlitzPlus)

[Guest]

(didn't see your post about accusing me of stealing my program from the generious person that let me use his sprites)

Okay, that was heartless. I spent freaking HOURS working on that, and now must suffer because I used maneesh's sprites. You don't believe I did it? Open that damn demo and copy the source code please. This is mine.:

If anyone here still doesn't believe me, then they can go fuck themselves. I can even send you almost 15 orinignal games with hand made sprites that lead up to this, showing my first time I got jump to work, first tim ei got something to animate, first game with ai, first game a backround, ect. Need I show them?

Hell, I even have my first text based game, where you could actually save your charactor's stats.

NOW DON'T GIVE ME THAT BULLSHIT THAT I COPIED MANEESH!!!

[JS Lemming]

Let me explain before you have a heart attack. First off, I never accused you of stealing any code.

The ships look exactly the same and the way the ship rotates left and right when you move is exactly the same.

I stated that the sprites looked exactly the same even the rotating ones. As for thew copyright thing, when I put a mr. green smiley face it usually means I'm kidding. I'm using the mario graphics no matter what. People know it belongs to nintendo, its not like I'm selling it. I'll put their name in the creds though.

[JS Lemming]

Back to the actuall topic.

Yep, I remember my first space invaders. Its was back in the day when I was always making games for our Ti83 plus'. Ok, I'll admit it, it wasn't that good but what do you expect for a calculator. You could only shoot 1 bullet at a time so that did sort of add stratagy. Hmm.... I wonder if I still have that thing.

[JS Lemming]

Oh, I'm not sure if you noticed this or not in your code...

Code: Select all

   If Not ChannelPlaying(bg_music) 
      bg_music = PlayMusic ("interim nation - future experience.mp3") 
   EndIf 

I experimented with the ChannelPlaying a while back and found that it slowed down game speed massively. But the only way I know how to keep bg music playing is to know the length of the song, then to start the music back up after that amount to milisecs. Since you probably don't have alot processing at this point you may not notice it. But later on when the game gets bigger, you could try the following to see if it is slowing stuff down.

Code: Select all

;This belongs in the main loop
if keydown(50) = false;key M
	If Not ChannelPlaying(bg_music) 
		bg_music = PlayMusic ("interim nation - future experience.mp3") 
	EndIf
EndIf

OMG! I saw that Maneesh fellow's demo. He used the exact same sprites as I did. I'm sorry I was an ass, I didn't know. Now I see why you could think that. Oh, and now I updated my game. It Still isn't a game, but you can now shoot, and enemies, a random number form 1 to 9 appear when you hit ctrl. (I did this to see If I had correctly made them spin.)

But I am still having a problem.....The first ones drawn on the screen spin fine. So do the second pair, usually, but when I hit CTRL again, the new ones don't spin. Can anyone help me out and tell me why not?

Here's my source code. I Didn't label the new parts because they are just there temporary.

Code:

   If Not ChannelPlaying(bg_music) 
      bg_music = PlayMusic ("interim nation - future experience.mp3")

GREAT idea! I never thought of that.

[JS Lemming]

I can't really help you because I don't know what the code does... I mean, I can't run the code cause i don't have the images and such.

BUT, as for the Background Music, you can use the technique I made for the Mario game. First you have to open up your music file an see how many seconds long it is (don't confuse with minutes). Then take that number and multiply by 1,000 to turn it into milliseconds. Take a look at the code below.

Code: Select all

;BackGround Music Vars.
Global chnBgMusic         ;pointer to music channel
Global MusicStartTime    ;holds current computer time in milli.
Global MusicLength        ;holds lenght in milli of the song.
Global MusicAddress$    ;holds location of the music file.


;Set the location of the file
MusicAddress$ = "interim nation - future experience.mp3"


;Main Game Loop
While KeyDown(1) = False

	;If the time has passed or song not even playing, play music and reset vars.
	If MilliSecs() - MusicStartTime > MusicLength
		chnBgMusic = PlayMusic(MusicAddress$)
		MusicStartTime = MilliSecs()
		MusicLength = 246 * 1000
	EndIf

Wend

Whats cool about this is that you can change music just by adjusting the address and lenght variable.

[MarauderIIC]

So you mean you hit ctrl once, works fine. ctrl twice, works fine. ctrl third time, it doesn't?

Try using print things to output the status of the variables you suspect might be the culprits. (For example, exospasms might not be getting itself set to true for some reason).

[Don Pwnious]

a random number form 1 to 9 appear when you hit ctrl. (I did this to see If I had correctly made them spin.)

What spins?

And ill see what i can do..

oh yeh i dont really like that background so you should make your own like this:

I hate randomly generated backgrounds, they never look good especially when tiled.

[Guest]

You were right, marauder. Thanks. I got that part fixed.

I HATE the background I had, I changed it. I need to post an updated screen shot, so you can see it and what spins.

Today, I got my enemies to move how I wanted them, at least the easiest enemies.

But it makes me so mad, I tried to make it so when my bullet collides with the enemy, the enemy explodes, (8 frames) and plays a sound. Somehow, I failed HORRIBLY. Now, for some unknown reason, it simply doesn't draw the enemies. Can someone help? This is my source code

Oh, and I too hate randomly tiled backrounds. They don't don't look good.

I made my backround look kinda 3Dish by tiling 4 images that move at differnt speeds. I personally think it looks kinda good.

[JS Lemming]

I might be best if you just posted the problem area of your code next time... it would cut down in the search and destroy crap. Hmmm... Well actually, we might need to know varaible declarations.... I don't know.

[Don Pwnious]

lol cool 3dish

[Falco Girgis]

God dammit arce, nobody is going to search through that huge thing for anything, especially not you. Use your brain, find the area that is screwed up. I swear to god, if you post that huge jarled, blitz disgrace again, I'll shove it up your ass! :?
