Okay... I think I really have a problem of optimization with my tilemapper   ... Does anyone knows a very fast and optimized 16x16 tiles grayscaled tilemapper (4lvl will be the best !) ? Or maybe there are optimizations remaining on my own tilemapper Here is the code :
.DRAWING
ClrDraw
StorePic
.BKG
conj(Pic1BK,L3,768)                                       // back-buffered background
conj(Pic2BK,L6,768)                                       // buffered background
G^16→F
V^16→U
For(B,0,4                                                     // screen height
For(A,0,6                                                     // screen width
{G/16+B*O+(V/16)+A+{97+L4}r+GDB0}→C        // the number of the tile to display
If C≠0
.BLOCK1                                                      // first part of the 16x16 tile
Pt-Off(A*16-U,B*16-F,C*32+Pic0
Pt-Off(A*16-U,B*16-F,C*32+Pic0)r
.BLOCK2                                                     // second part of the 16x16 tile
Pt-Off(A*16+8-U,B*16-F,C*32+Pic0+8
Pt-Off(A*16+8-U,B*16-F,C*32+Pic0+8)r
.BLOCK3                                                     // third part of the 16x16 tile
Pt-Off(A*16-U,B*16+8-F,C*32+Pic0+16
Pt-Off(A*16-U,B*16+8-F,C*32+Pic0+16)r
.BLOCK4                                                    // last part of the 16x16 tile
Pt-Off(A*16+8-U,B*16+8-F,C*32+Pic0+24
Pt-Off(A*16+8-U,B*16+8-F,C*32+Pic0+24)r
End
End
End

.HUD
0→L
For(I,0,11)
Pt-Off(I*8,0,Pic3HD+L
Pt-Off(I*8,0,Pic4HD+L)r
L+8→L
End


Thanks ! But it seems don't working : the app freezes I think there is an infinite loop in your code and I tried many things to correct that but that still don't working... Do you have an idea ?

Thanks a lot for your help !! I'll see that later

Don't worry, I'm still working on that
For those who want to see what I'm doing now, screenie just below !
And a not-so-secret game I worked on during my few free time

... and I also have a question : I read some stuff about interrupts and I want to know if they are stopped or if they crash when leaving the app... It would be very interesting if it was possible to schedule background tasks on the calculator executing normally the Ti-OS

This game looks incredible! Keep up the great work.

Nice, I'm glad this is still progressing Ti-DkS. I also like the Metroid sprite.

In this game, will Samus spin when jumping diagonally like in other Metroid games by the way? She usually jumped slightly slower but farther (and you didn't have to hold down an arrow key to make her continue going in the same direction, although it was harder to jump vertically that way).

Also is your other screenshot a Sim City clone? It looks pretty great.

Ti-DkS, that's looks awesome!

I know you've been told this before >1 time, but a walking animation would make this pure, pure, pure epic! It would completely change the way the game looks. Hope you can do that

yeah, a walking animation would be nice, but also better gravity to fall by more than 1 pixel per frame.

other than that, sheerly awesome   keep it up!

I have to agree with you on the gravity, it sometimes looks like Samus is floating, but he has been asked that and I think he said it was impossible to change gravity in the engine. Let's hope I am mistaken, though.
