As it's ported, gameplay should be the same.

I am quite certain it is a clone but don't quote me on that

Ohh sorry should read the discriptions better

Let's not hijack the topic, guys.

I did some benchmarks:

Code Select Expand


Used image: 320x240 full spectrum gradient

TI-Nspire OS 3.2.4

draw image string: 15.12ms

TI-Nspire OS 3.6

draw image string: 14.08ms
draw image resource: 14.51ms

TI-Nspire OS 3.9

draw image string: 14.16ms
draw image resource: 14.15ms

TI-Nspire OS 4.0

draw image string: 14.26ms
draw image resource: 14.21ms


3.6 and higher seem to be in general faster than 3.2 for drawing images. Speed between resources and string based images are basically equal. Using image resources also reduces the total size of your final tns document.

In any case is there still an actual reason to stay on 3.2? On a CX there shouldn't be really that much of a difference.

What about OS 3.1? I see no reason to stick to 3.2 unless you want 3.2.3 which is the only OS with arabic language, but 3.1, 3.6 and 3.9 got Ndless.

I just tested on 3.1 ...

TI-Nspire OS 3.1

draw image string: 222.6ms

That's about 15x slower than the other versions..

[CKH4]

I'm kinda surprised, I would expect speed not to change between different oses. Did you do multiple tests or just one per os?

[alexgt]

Ndless could be causing it but I don't think so without Ndless it still takes 15 seconds to get into the stupid file manager

Naturally I ran the test multiple times. Besides that I take the average of thousand drawing operations. The reason is because in earlier versions they used a very unoptimized drawing routine. I expected it to be slow, but not that slow.

Ndless could be causing it but I don't think so without Ndless it still takes 15 seconds to get into the stupid file manager

The only cause of this is unoptimized code.

OK that sounds good, if I ever get an nspire I'll get this game. As a feature request you should make another not exact port one with more ground and maybe another gamemode like super jump or super speed.

Holy crap, I've been still developing on 3.1, and I don't have a license of the TI-nspire Software, so I don't know how I'd use image resources.

Cumulating demos of the TI-Nspire Computer Software (student and teacher editions), you get 4 months of trial I'd recommend using 3.6 or later (though 3.9 got some nice lua additions)

In OS 3.1's case, there were massive improvements in image rendering in OS 3.2 or 3.6, explaining why it's so much slower in 3.1.
