Dead?, No. Slow definitely. It will become a self fulfilling prophecy if people don't contribute though. The only way for their to be activity is for people to work on projects and actively post. And yea, it seems Codewalrus was a large part of our specific drop in activity, though our falling out with TI Planet didn't help either. You will see that most of the members from there don't post here anymore either.

Yeah, it seems like none of the French users visit anymore and all of the English speaking users moved to Codewalrus. What happened with the TI-Planet break anyway? I heard critor got offended or something like that, but I don't know the details. Also, why exactly was Codewalrus created? It just seemed to fracture the community more. I noticed Codewalrus lists TI-Planet as an affiliate but doesn't list omnimaga as on (which is kind of odd, because DJ O founded Codewalrus).

I would program stuff, but I don't really have time to make any big projects, and no one is interested in small projects like maze generators. In addition, Nspire GCC on Windows is pretty buggy and doesn't include stdlib.

It seems like there are pretty much no new projects here. I've looked at the Omnimaga stats for post activity, and it seems like the whole site is getting a lot smaller (people probably would rather play games on a smartphone than a calculator - the decline in activity strongly correlates with the rise of the smartphone). This forum in particular hasn't really had any major projects for a while, even though it used to be relatively active when I joined in 2013.

TI will keep updating the OS and try to block Ndless. From my observations, it seems like it takes a considerable amount of work to find a loophole to install Ndless, and as the amount of people here gets ever smaller, the chance of finding a loophole will decrease. If Ndless isn't available on new calculators, there will be no new members, and C++ projects (which tend to be the most fun because they get the most out of the CPU) won't be usable, so no one will visit anymore. No GBA emulators, no crafti, etc.

In addition, nobody will create projects if nobody will use them. It seems like no one is downloading projects, which doesn't encourage programmers at all.

So can we officially wave goodbye to TI-Nspire programming? There doesn't really seem to be a good solution to revitalize this forum. It seems like TI-Nspire programming is a thing of the past now when smartphones are plentiful. It seems like the whole site, along with all the other calculator programming sites, will die pretty soon when people ditch calculator gaming in favor of smartphones.

Thoughts?

Looking at the post graph, it seems like the activity stayed relatively stable during 2013 (100 posts/day) until the end of 2014, when it nosedived to around 20 posts/day, and now it seems like it's at 10 posts/day. RIP Omnimaga. Any idea on why the post count decreased so rapidly at the end of 2014?

Is there a way to send information between 2 nspires that are linked using Ndless?

e.g. transferring variables

There is the isKeyPressed function, but that only detects the state of the key.
Say, for example, open a text editor and hold a key. One character will show up at first, then after half a second or so a bunch will start showing up rapidly.
Is there a function to capture this type of input in the SDK or should I implement one?
I'm curious because in a program I'm making I'm using tabs to loop through things, but it just loops through everyone really fast.

Interesting, but it will be sad if a ton of game makers come out for nspire, because then it would become pointless to actually program games.

Not really.
The Nspire's 132MHz CPU can't handle much, and most game makers I know have lots of overhead.

Sorry for all the posts, but I have another problem :L
player.position_x=player.position_x_temp-player.drillcount/player.drillmax;
doesn't do anything because drillmax>drillcount, so drillcount/drillmax=0, but
player.position_x=player.position_x_temp-20*player.drillcount/player.drillmax;
moves the player 40 pixels to the left (which is very strange because it should be at most 20)

I tested
player.position_x=player.position_x_temp-1.1*player.drillcount/player.drillmax;and it also moves the player 40 pixels to the left #include <os.h>

(code still needs to be cleaned up a lot)
Probably some other derp fail, but was wondering
You can view the glitch in the attachment




(gcc occasionally glitches for me in codeblocks (the exact same code compiles to different things at different times) because my computer is weird, but I've tried this lots of times)

you only set the seed once all at the beginning of your program.

Woops
Epic fail
Looks like I still have much to learn
I spent a long time looking at the code, and just realized I added the line in the wrong place

I'm trying to make a drilling game. When the player first starts, the program generates some dirt blocks with minerals 50 rows deep and 40 columns wide, or 2000 blocks. However, using time as rand gives me really crappy number generation (all the blocks in a column are the exact same if I use time as rand). I've tried using a couple other things, like using SDL_GetTicks() (which produces the exact same thing every time by itself, so I also need rand) and xoring the int a couple of times, but I still get really poorly generated blocks. Also, I still want it to be simple enough that it doesn't lagg much. Any ideas?




My current block generator:


void newrow(uint16_t row)
{
srand(time(NULL));
chance[0]=1000/(abs(pow(row-10,1.1))+50);//1000/(abs(pow(row-row_where_it_is_most_common,range_of_how_common_it_is))+100/percent_of_blocks_in_most_common_row)
//coal is found with a frequency of 100/50=2% of blocks in the row in which it is most commonly found
//coal is most commonly found in row 10 (actually 11 in the array, but 1 more or less doesn't make a huge difference)
//coal is commonly found in a large range of blocks, note the low exponent
//note that 0 in this array corresponds to 2 in blocktype
chance[1]=1000/(abs(pow(row-30,1.1))+60);//iron is found in 1.667% or 16/1000 blocks in the generator at max, and is also very common
chance[2]=1000/(abs(pow(row-50,1.1))+80);
chance[3]=1000/(abs(pow(row-80,1.1))+20);
chance[4]=1000/(abs(pow(row-110,1.3))+100);
chance[5]=1000/(abs(pow(row-150,1.5))+150);
for(int i=0;i<40;i++)
{
tempint=((SDL_GetTicks()+rand()+i)^(row*i))%1000;
sleep(1);
for(int z=0;z<6;z++)
{
if(z==5)
{
if(rand()%8)
{
map[row][i]=dirt;
break;
}
map[row][i]=nothing;
break;
}
if(chance[z]>tempint)
{
map[row][i]=(static_cast<blocktype>(z+2));
break;
}
tempint-=chance[z];
}
}
}
