Dimension
« on: February 18, 2011, 11:15:11 pm »
Speaking of this "random garbage" popping up, it gave me a game idea.  A platformer, with essentially no purpose (except to have fun/kill time) that reads from the RAM, in which you can switch 'dimensions' (inspired by the random blocks appearing and disappearing at random in the old versions).  
So... thanks for that ;D
[↑ quoted from sandland thread]
So, I started by modifying an old version of Sandland to see what I could come up with.  It's worked pretty well.
See first screenshot. Screenie removed b/c of confusions.
You can probably tell how it's supposed to work.

After that, I went to code my own.
It reads starting at a random spot in RAM.  The 'other dimension' is that pointer plus 32768 (65536/2).
It doesn't work as much.  See second screenshot.

Can someone look at the source and see what's wrong?  It seems to not be detecting tiles that should be there, or standing on a tile that's not there...

Variables:
E: starting pointer
I,J: tile offset from E.
N,O: pixel offset from I,J
D: whether or not player is on top of a tile
FGKL, PQUV: used for detection of tiles
Z,Θ: X- and Y-velocities

Thanks in advance ;D

Controls for Dimension: left/right: move left/right
2nd: jump
Alpha: swap dimension
Clear: quit

btw I'm not dropping Tio for this, I'm kind of using this to learn more about smoothscrolling tilemappers before I apply it to Tio.

That's pretty cool. I was going to make a game called "flipside" based on this concept, but without using Random RAM.

Thanks ;D
I was playing the first one about every other class at school today, esp. because there are so many of the teachers sick for some reason and I had like three subs :P
Kind of addictive actually, once you come up with a sort of goal (in my case, try to get as far up as possible) ;D

Strange...I've heard of HL2 but I've never played it before...

I'm hoping to get this figured out soon, though.  Smoothscrolling, random ideas/explorations and I don't seem to get along very well :P

Okay, I'm taking the night to try and get this fixed.

Interesting, in future versions you could maybe add some sort of goal to the game where you must collect an item or something and it displays how close you are from it and the faster you get to it, the higher the score.

That would be really hard.
The 'level' this uses is the RAM.  Like, any spot.
What it does is
rand→E  //not a typo
and later it references {E} as a pointer.  IDK if there's a way to add in stuff without editing the 'level', which is a random spot in RAM.

Ah ok, you could maybe add the object the early-Illusiat/ROL way, where it wasn't part of the map data.

How is that done?  Does it have its own pointer of something?

In Illusiat the object Y and X location was stored in 2 variables. If your position was equal to both then it triggered the event code.

Hmm...so one would try to collect coins or something spread through the RAM...could call them "corruptions" or something lol
I think I'm getting a storyline idea...

Thanks ;D

One thing to keep in mind, though, is that using variables you would only have one coin. It might be best to store them in an array like in L1 and run a For loop through them to display them if they're in the screen.

True.  Maybe when you collect one, another pops up...the last one can be in the variable buffer so it's hard to get at as the blocks are going haywire. :evillaugh:  I'm kind of liking this idea... I'll try to implement it once I get the elementary tilemapping working :P

That could work too.

Also what would be cool is if we could be able to move on 2 different type of tile at a time and swap layers or something, because that way I am sure the game would be even more fast-paced, as someone could switch extremly fast between layers to fall faster and faster.

Pretty much the main part of this game is its 'swapping layers'...watch this and you'll see kind of what I'm shooting for.
It's the image from above.

About the blocks:
Dark gray=current layer
light gray=other layer
black=both layers

Do you mean more than two layers?
