Metal Slug: Assault

Hmm, not really long, the normal hibernation autonomy of the Prizm is around 160h IIRC. The Nspire has an advantage if using an ARM which is quite battery efficient IIRC but I still can kill the battery in one day of playing GBA games.

Ah right. Thanks for the info. I'll definitively need to watch out if I play ASM/C games at higher speed on my PRIZM. As for the Nspire it depends of the OS and hardware combination. On some hardwares from early 2008, if you install both Ndless 1.0/1.1 and OS 1.1 you will get about 10 minutes of battery life when  playing GBC games due to a power management bug. On top of that turning the LCD ON will be very hard (you need to run a reboot program while the screen is disabled so it's kinda hit and miss)

That's enough off-topic please.

Back on the subject, I successfully implemented the "ground physics" engine I had in mind, so that means non-horizontal ground is handled seemlessly. The algorithm has a constant complexity, so 5 lines or 1000 will make no difference performance-wise
Also, I figured out a way of handling those collisions regardless of where the character is, so that means that virtually, no overflow can happen. In practice, that means that any level can be infinitely long, as long as the right-side coordinates fit in 16-bits variables

Did I mention that all of this was less than 2 kB ?

I'll post a screenshot as soon as possible.

I really want to have some talks with you to understand the collision system, please.

[matrefeytontias]

No problem, anytime

Will we get a screenshot later today? That physics engine sounds impressive.

[matrefeytontias]

Yeah, just the time to finish cleaning my guitar and transfer and shoot and stuff.

(Off topic : do you have telegram? Its a fine way to communicate on one-on-one or in group)

[matrefeytontias]

No and enough with the off-topic >_< you have PM for those questions (and SMS for instance).

[Snektron]

Or maybe make a forum post about it (there are probably more users who want to know )

[Dream of Omnimaga]

Matref please, there are more polite ways to warn people to get back on-topic than scolding them like n00bs. You should not make people scared of replying to your topics.

That said, I am amazed that you managed to fit the engine into 2 KB so far. I am curious how fast this will get with actual sprites.

[matrefeytontias]

I already asked to stop with the off-topic because there's already one page and a half of that.

Well, it's really because the calculations are really light. There's one loop for finding the line and a single If block to do the calculations, and that's it for the whole frame.

[Dream of Omnimaga]

Yeah just making sure CW remains  friendly place. Anyway from what I read on IRC, don't forget to backup often. It would suck if after 2 months of development you accidentally introduced a bug you cannot repair in the engine.

[matrefeytontias]

Well the problem is that I do way too many backups. Like, I erase all my working backups with backups of broken source because I backup before testing, and when I see it doesn't work it's too late. That's what happened, so I'm restarting from scratch (like I said, it's only 2 kB worth of code so it should be fast).

[Duke "Tape" Eiyeron]

Aw, that shucks. Hope you get that fixed in no time!
