Flappy Bird - Hayleia
« on: February 18, 2014, 04:00:38 pm »
Many people already made their version of a Flappy Bird clone. So I thought "why not me too ?" :P
I think it is useless for me to explain the gameplay, it's in every other topic. So I guess it's just screenshot time (6MHz, as usual).


As you can see, collision detection is missing and the game needs a menu and such things so no release for now. I'd also like to optimize it a bit so you'll have to wait :P
Anyways, tell me what you think of it :)

I think with all of these flappy clones combined, we get more downloads than the real game.

I, for one, welcome our new Flappy overlords. XD

Anyways, I love it! Better than ClrDraw's version! (And I don't say that often)

Yeah, but unfortunately, we don't make money :P

Anyways, I love it! Better than ClrDraw's version! (And I don't say that often)
Well, thanks, but how can you say that before trying it ? :P

(grayscake ? :P)
Thanks :)
Compiled for Noshell, i's 3043 bytes for now (because of 1536 bytes for the background, but I could save a lot considering that half the background is monochrome).

Haha XD Either I suck at computers or I was thinking about portal too much!
But that's not a bad size considering the grayscale. I can't wait to play it :)

This looks quite good actually. What I am wondering is if parallax scrolling would slow the game down?

It depends. If I keep everything 4 lvl of greyscale, then yes, it will slow down a lot. But if I scroll a white+grey background with only three levels of grey (pipes would be black then, but dark clouds would not be possible), then it will speed up.

Thanks everyone for the support :)

Ah ok thanks for the info. Is it just due to having to redraw everything or because of possible flicker?

It's due to having to redraw everything. Right now, I just draw pipes once and then keep shifting. And you read right, I draw once, I don't keep drawing while it's half offscreen, I draw them once in L1 then shift L6 (and L3) with a part of L1 ;)
But If I went parallax (with 4 lvl of grey, 3 is not a problem as said previously), I'd have to draw all pipes, refresh screen, erase pipes according to their positions or reinitialize the background (don't know which is slower :P), shift the background then draw all pipes again. This is slow, but also forces the placement of the "refresh screen" part while with my current code, I can use an interrupt.

Can someone explain me why setting GreyMode at 0 plays faster than setting GreyMode at 3 ? Because that sets GreyTimerMax lower, but the frequency of the interrupt is also lower so nothing should happen more often.

edit and don't tell me "Draw and Erase are very very unoptimized, you are making the same calculation several times", I know, but I planned to change everything in the drawing routine anyway so I didn't look this part very often. And r3 in the main loop is useless, you can remove it.
Same for the "LnReg FnOff FnOff" at the beginning, the initialization when testing is always the first thing subject to changes.

I just noticed on the screenshot that there was an unwanted white outline around "pipes" so I removed it here, but that still doesn't answer my interrupt question, so if anyone has a clue, please share. The code is in spoiler too.

.take the hex code from the previous spoiler, I removed it because it caused a scroll bar to appear

.same here

I also attached a gif so you see what I am talking about. When I choose 0, the game plays fast, but when I choose 3 it is slower. I don't even understand why the slow down is this way. I would have understood 0 to be slower than 3 because it decreases GreyTimer more often (even though it DispGraphes as often), but it's 3 who is slower.

Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.
