makes you wonder why nobody's bothered w/ a port of the gba mario games. it was more fun when you had 4 characters to choose from w/ different stats, and you killed things by picking them up and throwing them at others.
lots of fun puzzles too.
add quicksand lol

A port of a port, I presume.
To be honest, I didn't know that game ever saw the light of day (officially) outside the NES. |

Yea, If I knew how to write a masked clipped routine I would.
Same with my shooter. Can't write a clipped routine for it either (it's bugged or something). |

You dont need to write one, do you? There are plenty online somewhere.
If not for speed: Save the pixels behind your sprite. Then OR the mask on it and then XOR the (inverted) sprite on top of it. |

Yeah, I wouldn't bother reinventing the wheel unless you're wanting to prove to yourself you can code one. This game is already advanced to the level where I think that would be unnecessary. Besides, those routines aren't online for *not* using.  |

I'll find a balance when my project gets farther. Atm, I'm working on the general stuff and tiding other things up.. Like not picking up a ton of things at once, or hitting question blocks from unique angles, and not picking up enemies while on an elevated platform, etc.
I think i'm just gonna mix super mario with the question blocks and crap with the throwing stuff.. make it a bit more unique. heh.
If it wasn't for school, i'd probably be alot farther. :\ |

Lol, yeah I feel you on the whole school thing. As lazy as it might sound, school takes up a ton of time. For real. Then on top of that, I wonder if you work at all?
But regardless, the project is looking amazing! :D
Oh and about the masked sprite, just do a sprite that takes the entire background, taking the mask, then doing reverse bits with the and.
I'm terrible with explaining, so I'll try here:
say the background byte looks like the following:
01010101.
Then say the sprite byte looks like this:
00001111
What you don't want the results to look like is this:
01011010
So what you do is create a mask that you AND with the original Byte. The mask bit would look like this:
11110000
and then this is where you would AND the original Byte and the mask together. Then go about and just place your sprite however you normally would. So your final sprite byte would look like 01011111. :D
I hope that helps? Like I said, I can't explain things if my life depended on it. Once I get my computer back again, I'll try to show you an example of my masked sprite routine.  |

Quote: I'm pretty sure he understands that much, but if I'm right, then his problem is properly splitting bytes in two if the sprite isn't aligned, and still masking it correctly.
I think it gets worse when the sprite is clipped and can be off the screen. From the XOR routine clipped from 28 days, I think all the registers are already tied up, making the mask a super pain. Haven't really analyzed the situation, but I don't think there's an easy modification, but then again, I could be wrong. |

probably don't want to do that w/ gray.
i think sigma's probably already uses shadows, but i don't remember |

Quote: or something? That should be able to free them up for a moment with use of minimum clock cycles. Although the routine could already be using them though... I'd take a look, but I'm a little tied up right now
Just save the registers that you need for the moment to memory, then do what you gotta do for the masked routine. It shouldn't be that slow, should it? It looks like you have a few cycles to spare anyway It's fast enough as it is
Was thinking of that, but i'm using an interrupt timer, so I would have to disable interrupts, meaning my timer would be off depending on how often the pics were drawn. :\
I could use it for less called statements, but drawing is probably the most common command. :P
Having the timer off could be okay for a few objects, but i'm not certain over a larger array of objects. |

Jumping things and pow block :|
Glitchyish atm, but when I actually get some time i'm gonna make a scorer thing for the pow blocks =X
Gonna finish sometime in summer of 2009. It will be uber epic and all that crazy stuff you saw in Super mario advanced is gonna be here and stuff like that. :]
School has kept me from any real progress, grrr. > !

I should be using a clipped mask routine, but i'm to lazy to make\find one. |

lol, even my suckey program uses an bitmask routine i made myself...
[attachment=2502:attachment]
here (it runs at 50 fps btw)
it doesnt need to be clipped because im using an 14 wide buffer
when its clipped, its already off-screen |

nah, they allow you to have detailled bg
and they make grayscale a hell lot easier |

Greyscale takes up to much speed and isn't worth using in a side scroller unless you can write epically effecient code.
I was gonna do greyscale, but it's to slow.
I don't know what you're saying about about making greyscale easier(?) with masks.
oh and greyscale and cool bg's are over rated :]
