Bump !

I just received my CX CAS (Yay !), and I noticed that this game was painfully slow on CX.
So I modified it to adjust the speed to the CX. The speed didn't change for grayscale nspires.

Could anyone tell me if this is too hard (on a CX) ?
PS : I managed to reach 9100 points !

Jim Bauwens · « **Reply #76 on:** November 23, 2011, 10:26:33 am »

I would try to do some tricks with optimizing functions, like localizing variables and stuff like that.
If there are some images that can easily be replaced with fillRect and stuff like that, do it!

Chockosta · « **Reply #77 on:** November 23, 2011, 10:37:57 am »

I don't use images.
I only use fillPolygon...

And localisation, on the nSpire, seems to be less useful than on PC.

Jim Bauwens · « **Reply #78 on:** November 23, 2011, 10:40:33 am »

Oh wait
I was thinking of bobby carrot :p

Localization really does allot for me

Anyway, try to look if there is any code that can be simplified, like calculations.
I'll take a look at the source too.

Edit:
Can you share the source

Chockosta · « **Reply #79 on:** November 27, 2011, 08:01:03 am »

Oh, I haven't seen your edit ! Sorry...

Now the speed of the cubes automatically adapts to the framerate.
So the speed is the same on CX, clickpad, or computer software.

The new release is attached, with a color screenshot...

Here is the source :

What I do in my code if I use a table value quite often in function is localize it (local x = cubes[x ]).
This way accessing the variable is much faster.

And it really helps

Chockosta · « **Reply #81 on:** November 28, 2011, 12:05:38 pm »

Thats a really useful habit. (+1)

I haven't anymore speed problems with CubeField, but this will help me for other projects.
I will try to remember that. Thanks.

Thanks

I'm glad that you have solved all your issue's too

DJ Omnimaga · « **Reply #83 on:** December 25, 2011, 10:12:51 pm »

I like the new update. Two suggestions I got are:

-Allow going behind blocks. Right now we have to wait until we're about 4 steps away from a block before being able to move behind it, else we die.
-Add a minimum value for the space between the two blocks appearing at once, so we don't end up stuck in dead-ends as much or without enough space to go between two blocks.

I think the original cubefield allowed cubes to get as close as touching edges with each other, but not overlapping. That could be something to consider.

This would be quite hard to do. I would have to change my collision detection. And since my blocks are squares and not cubes, they dont have a defined thickness. (I'm not sure this is the correct word)

This is possible, but I think it would possibly become too easy. I will test this.

Do you think using the 3D engine thing you've been using, that you could make the blocks 3D?
Also, do you plan on making the game so that in between the levels are those criss cross paths? (And then later the colors become black and green?)

Chockosta · « **Reply #87 on:** January 19, 2012, 12:10:25 pm »

My 3D engine is too slow for that, it wouldn't be a good idea to use it.

About criss cross paths, I can try... But now I'm working on others projects, so you have to wait a bit

It is a great project that has been nicely done. I checked the other day, it is in the top 10 files downloaded in the last 7 days in the Ti-nspire section of ticalc.org. Well done!
