[Resolved] Matrixes and RGSS

[lobosque]

Why the game lags (A LOT) when it is countinuosly messing with matrixes? for example:

matrix = [[1,2],[3,4],[5,6],[1,2],[3,4],[5,6],[1,2],[3,4],[5,6],[1,2],[3,4],[5,6],[1,2],[3,4],[5,6],[1,2],[3,4],[5,6],[1,2],[3,4],[5,6]]
for i in 0...matrix.length
  matrix[i][0] = 8
end

The game lags a lot, and i need so bad to use a matrix for what i'm doeing

It's not a matrix, it's a multi-demsional array (yes, kindof the same, but Ruby actually has a matrix library & class).

Remember that arrays are list of other objects (class X), so you can put arrays into arrays into arrays, etc.

The game shouldn't lag from that. All it does is pass through each mini-array and assigns the first value something else. Something else is causing the lag.


Also, you might want to look into the RGSS Table class if you are only using numbers.

Thanks i'll take a look.
But i'm sure that is the 2d array that is causing lag, because if I use 2 1d arrays, it works normally (when its there that it should lag, since its much more painful to check in 2 arrays, one for x and another for y).

Well how big is this 2d Array?

I really don't see it causing lag unless it was really really bug

and yes there is a Matrix class but it is not part of the ruby standard library I'm pretty sure you can google it and get the source for it if you want

 

[lobosque]

The length of the 2d array is 46.

 

[Trickster]

no thats not going to lag, I remember having a 2d array length 6 height 12 for my Tetris Attack minigame and I've seen no lag

It is something else generating the lag

Do you have
1) A Window's refresh method being called in the update method
2) Calling Bitmap#draw_text, Bitmap#hue_change or Sprite#angle= every frame or very frequently
3) Running very, very large loops

 

[lobosque]

The loop is big, but what I don't understand it's why it don't lag when using two arrays, and lag using one 2d array =/.

 

[Trickster]

Well you could, you know, post the code so we can have a look :p

 

[lobosque]

Ok, i'm gonna make two versions, one with 2 arrays, and one with 1 2d array and edit this post as soon as it's done (3 minutes xD)

----EDIT----
Well, Now it works xD.
I'm not gonna tell you guys what was the problem or i'll have my head pawnt

 

[Selwyn]

let me guess,

you were using the matrix as a constant and were initializing it every frame, right?

 

[lobosque]

Nah, I was messing with your 2d array at the same time :P.

(This is a little off-topic but, remember the obstacle thing that i told you about in msn? I have just finished to write the code :D)
