Metal Max 2 Demo! [Updated:07/21/2013]

Master_Programmer · June 20, 2013

Okay, here we go, this is Demo #2, with a little under half the game playable.

There's 4 stages complete, and a 5th with a boss, and a complete layout, but very sparse enemies and no healing items.

Switch Select after stage 2, changes your character.

If you have collected 3 white gemstones, and you have more than one full life-bar, you can turn into a "Giga" state, with either character, that grants invincibility to most attacks, at the cost of very slowly draining your life down to one bar.

To activate, jump, and as you'removing upwards, press the up direction on the joystick.

After stage 5, though, the game is essentially over, since there is no real stage-layout for any stages beyond 5.

Have fun!

Edit:

I fixed the immortal first boss bug. No bosses are immortal.

I also added a Full-fledged, but very short, full-screen cutscene, that starts just as you reach the screen for the very first boss.

Download the "BugFixed" version, as the previous one has an error in the boss intro to the stage 3 fight, where The "original" max gets stuck in an intro loop, and is unable to be attacked.

It depends on how varied you can make your shizz. If not alot of puzzle and or monster types are available you want to keep it short and sweet.

Like loon says, it's hard to say unless we have an idea of what the extra stages/extra screens would mean in context. What would the difference be?

Also, when comparing the combat types between Megaman and Sonic, do you mean whether you jump on enemies to kill them versus shooting them? Why not have both?

Not sure I'll have the cycle-count for both types of combat, but I can try.

I'm down to anywhere from 500-700, without enemies((But with this game's version of 'Rings' from sonic, which are green gemstones)), Mostly because I'm using advanced collision detection, which allows the sides of walls to be solid, despite being a platformer.

But, I *CAN* try both, if you two would like.

Heck, I could make two or three engine types, and let everyone pick out which version they like best. :3

EDIT:

Also, the extra screens for each stage, with less stages, would mean I have less work to do coming up with stage themes and enemies, plus longer and more complex stages.

As for enemies and puzzles...I'm not sure how I can do the latter, but as for enemies, I'll probably have at least 3 types in general, but my goal is 3 unique enemies for each stage.

A grunt, a medium enemy, and a strong enemy...plus a boss.

Master_Programmer · June 20, 2013

And now the game is going absolutely insane, only erroring when I have any check for "Joy0Left" in place. I can remove anything else, and it still errors, but when I remove the joy0left, it's fine.

Cybearg · June 20, 2013

Sounds good to me.

I'm surprised that your collision detection is gobbling up that many cycles, leaving you with just 500 left. Is that the case, or did I misunderstand?

When you say "advanced", is it based around collision() statements or pfread()?

Master_Programmer · June 20, 2013

Pfread.

The "joy0left" if statement there is crashing everything, and the source-code ONLY compiles when that one line is missing!

main
temp3 = ((player0x-15)/4)+1
temp4 = ((player0x-15)/4)-1
temp6 = ((player0y-1)/8)-1
temp5 = ((player0y-1)/8)-1

ac=0
if yvel<>0 then ac=2:jump=1


if joy0right then xvel=xvel+0.084 : ac=1
if joy0left then xvel=xvel-0.084 : ac=1


if joy0fire && !jump then yvel=-1.5:player0y=player0y-2: ac=2: jump=1
if !joy0fire && yvel>120 then yvel=0
if xvel>3 && xvel<120 then xvel=3
if xvel>120 && xvel<252 then xvel=252

yvel=yvel+0.086
if collision(player0, playfield) && pfread(temp3,temp6) then if xvel<120 then xvel=0
if collision(player0, playfield) && pfread(temp4,temp6) then if xvel>120 then xvel=0
temp3=temp3-1
if collision(player0, playfield) && pfread(temp3,temp5) then if yvel>120 then yvel=0
temp6=temp6+1
if collision(player0, playfield) && pfread(temp3,temp6) then jump=0: if yvel<120 then yvel=0

if xvel>0 && xvel<120 then xvel=xvel-0.038
if xvel>120 then xvel=xvel+0.038

player0y=player0y+yvel
player0x=player0x+xvel
skipmove
if player0y<10 then player0y=10
if player0y>85 then reboot
if player0x>138 then player0x=15:screen=screen+1: gosub getitem
if player0x<15 then player0x=138:screen=screen-1: gosub getitem
if dir=0 then REFP0=$08

Even stranger, the statement works if I turn the joy0left to a joy0right, or up, or down, or ANYTHING else.

If someone can tell me what's going wrong, then please, by all means, do.

Until then, I'm going to delete lines until I come upon the problem, then CTRL+Z all of it back, and tamper with the bad line.

EDIT:

Turns out a variable of mine had a bad name. "ef" was the name of a bit I had, and the compiler hated it.

Alright! Here's the very first demo of Metal Max 2!

Left and right move left and right, fire jumps, and down shoots!

The green things are gems, pick them up, they give you health!

instead of lives, I'm using Metroid-style energy tanks, though they won't be called that. Over-filling your health, by grabbing gems, will allow you to fill up a "tank", having the maximum of 3 spare tanks, or 4 life bars total.

The demo is only one stage, 10 screens total, with 2 different kinds of enemies, a small weak one, and a large strong one.

Enjoy~!

Master_Programmer · June 20, 2013

Added a very simple puzzle....lets see if you all can figure it out. :3

Edit:

There's no boss yet, so I put a death pit that reboots the game. >.>

I have Demo #2 up!

It has a solid 3 stages, each with a unique boss!

Stage #2's boss, after defeated, needs to be collided with, to activate a tiny cut-scene. That boss, will actually be playable in the full game...She's Max's love-interest, a gal named Tora. ^^

Boss #3 is a clone of Max from the first game.

The stages in the demo are as follows:

Stage 1 - Melody Meadow

Stage 2 - Chaotic Castle

Stage 3 - Poison Paradise

Each stage, except #3, has a small puzzle, the reward being a White Gemstone.

These, in the finished product, will in effect be like the Chaos Emeralds from sonic. Obtaining all of them will allow a temporary powered up form of either character...but for now, all they do, is charge your health up to the max.

Amazing work! I'm very impressed by the sprites, levels, and your overall use of your limited sprite resources to still make the game feel full and interesting. Superb job!

Out of curiosity, how much space do you have remaining after all this?

Personally, I couldn't get past the third stage because of the slidy movement + precision platforming. Urk!

Also, the first time I played the second boss, he charged over to me on the left side of the screen and knocked me up and out of the top of the screen, where I was stuck.

     1737 bytes of ROM space left in bank 1
     630 bytes of ROM space left in bank 2
     627 bytes of ROM space left in bank 3
     426 bytes of ROM space left in bank 4
     4052 bytes of ROM space left in bank 5
     4052 bytes of ROM space left in bank 6
     4052 bytes of ROM space left in bank 7
     2132 bytes of ROM space left in bank 8

Really, my big problem isn't space when it comes to this game...it's my staggeringly low cycle count left.

I'm trying very hard to optimize my code as much as I can, but I'm starting to get to the point where I'm not sure I have much left I can optimize.

Personally, I couldn't get past the third stage because of the slidy movement + precision platforming. Urk!

Yeah, I'm still working on that...I'm trying to make him a tad bit slidy, but not too much, and that perfect balance is strangely hard to get.

Also, the first time I played the second boss, he charged over to me on the left side of the screen and knocked me up and out of the top of the screen, where I was stuck.

Really? That was the blue boss you're talking about, right? I'll look into the code there, and see if I can fix that.

Cybearg · June 24, 2013

That boss on the second stage is also surprisingly easy to beat after how long it takes to finish off the first boss.

What is it that's taking up all those cycles? Is it your collision detection? Is the code going through a bunch of if-then statements for AI? Are you jumping between the banks a number of times per loop?

She's not supposed to be tough, because she's not actually a villain. She mistakes you for being the recently resurrected villain, the boss from the first stage. She's easy, because Tora has the exact same HP as the player would, if they had only 1 bar of life.

What is it that's taking up all those cycles? Is it your collision detection? Is the code going through a bunch of if-then statements for AI? Are you jumping between the banks a number of times per loop?

I'm going to guess it's both the advanced Collision Detection, and the enemy AI. The bosses are quite complex, code-wise.

Cybearg · June 24, 2013

Odd that the collision detection would take that many cycles. I'd recently fiddled with collision detection in a game I'm working on and I got what I thought was a pretty complicated system only drawing 300-400 cycles on a regular basis. Though maybe that's considered a lot, I dunno.

I'd definitely suggest skipping most of the AI code unless it's actually being utilized. The cycle count is about the same, around 125-300, regardless of what's on-screen. When it's an empty screen, it should be able to lighten up a fair bit, I'd imagine. Perhaps an on...goto or on...gosub statement that only calls the necessary AI code when there's actually an AI utilizing it in play?

  temp3 = ((player0x-15)/4)+1
  temp4 = temp3-2
  temp5 = ((player0y-1)/8)-1
  temp6 = temp5 +1

if collision(player0, playfield) && pfread(temp3,temp5) then if xvel<120 then xvel=0
if collision(player0, playfield) && pfread(temp4,temp5) then if xvel>120 then xvel=0
temp3=temp3-1
if collision(player0, playfield) && pfread(temp3,temp5) then if yvel>120 then yvel=0 
if collision(player0, playfield) && pfread(temp3,temp6) then jump=0: if yvel<120 then yvel=0

That's my collision detection. I'm fairly sure that's the main culprit of my cycle-usage.

That's exactly what I'm doing. I actually have each "Object"((Non-player sprite)) as a separate subroutine, called to by a bunch of goto's.

That's all of my enemy/object AI so far. The very last one, the "Dead" there, is to kill the player upon reaching the end of demo screen, to make 100% sure they don't find a way to the next of the ((Unfinished and missing)) stages.

Good news. I just freed up around 1000 to 2000 cycles, by removing the invisible line of playfield blocks with "pfres=11".

Things are back to running real smooth!

Cybearg · June 24, 2013

Awesome! Grats!

By the way, why aren't you using an on...goto statement instead of all those if/then statements? It'd save you a ton of space.

If the issue is the bB space limit for single-line commands, I'd recommend you use a bit of Assembly there to do it instead.

If the issue is the bB space limit for single-line commands, I'd recommend you use a bit of Assembly there to do it instead.

1737 bytes of ROM space left in bank 1
630 bytes of ROM space left in bank 2
627 bytes of ROM space left in bank 3
426 bytes of ROM space left in bank 4
4052 bytes of ROM space left in bank 5
4052 bytes of ROM space left in bank 6
4052 bytes of ROM space left in bank 7
2132 bytes of ROM space left in bank 8
Really, my big problem isn't space when it comes to this game...it's my staggeringly low cycle count left.

I'm trying very hard to optimize my code as much as I can, but I'm starting to get to the point where I'm not sure I have much left I can optimize.

I said it before, space isn't an issue. I've got an entire 3 banks completely unused.

And I'm starting work on Tora! She'll be playable, and able to be switched to at any time after stage 2!

And I'm going to work on the "Giga" forms for both characters, a super-soniceqsue transformation, once you obtain all the special gems.

Cybearg · June 24, 2013

Well, let me rephrase: it would save you a few cycles.

Master_Programmer · June 24, 2013

Well, let me rephrase: it would save you a few cycles.

Ah. Well, I'll probably try that out if I run out of my newly-freed cycles.

Master_Programmer · June 24, 2013

Okay, new demo peeps!

In this, I fixed the sliding issue with Max...his movements are *much* more precise and controlled.

AND!!

After you beat the blue boss, boss #2, AkA Tora, you can play as her. Press the Select Switch to alternate between the two!

Tora Accelerates much faster, and jumps higher, but slides a bit, so be careful!
