Well I was a little bored and modified the last one. This is not very practical for stuff such as a tilemapper (I get 10 fps on one sprite) but for other stuff it can be useful maybe. In its current form it just animates through smallest zoom to the largest.

Code: [Select]
:.MAGX8
:ClrDraw
:ClrDrawr
:[3C42A59999A5423C]→Pic1
:[0000000000000000FFFFFFFFFFFFFFFF]→Pic2
:For(Z,10,80
:ClrDraw
:Pt-On(0,0,Pic1)
:For(C,0,8)
:C*Z/10→A
:For(D,0,8)
:D*Z/10→B
:Pt-Off(B+17,A,((pxl-Test(D,C)) and (C<8) and (D<8))*8+Pic2)
:End
:End
:DispGraph
:End
I am sure someone could poke this code with Quigibo's Axe of Optimization (sorry, stolen from Weregoose TI-BASIC stick of optimization... couldn't resist :P)

 ;D Wow!  That's really cool!

On the topic of optimizations, why is there D<8 and C<8?  Can't the loop just go from 0 to 7 instead?  Other than that its pretty optimized.  But if you really want speed, you can actually read from the sprite data directly instead of using the getpixel command and then the sprite doesn't have to be drawn first either, but it is a little harder.

Oh I did that since I was only drawing one single sprite. If I stop at 7, the last row and column will always be 8 pixels wide.

Could you explain how to draw from sprite data directly? Axe lacks a command to read individual bits from data, which I assume I would need to do that...

You wouldn't use a bit command anyway since it would be a slower.
Code: [Select]
:.MAGX8
:[3C42A59999A5423C]→Pic1
:[0000000000000000FFFFFFFFFFFFFFFF]→Pic2
:For(Z,10,80
:ClrDraw
:For(C,0,8)
:C*Z/10→A
:{Pic1+C}→E
:For(D,0,8)
:D*Z/10→B
:Pt-Off(B+17,A,E^2 and (C<8) and (D<8)*8+Pic2)
:E/2→E
:End
:End
:DispGraph
:End

Oh ok I thought you meant a way to also draw each individual columns of pixels one by one too, not just rows. I guess just rows are not too hard then (well I don,t really understand the code that much but it seems to make a bit more sense than what I thought).

Sadly I did not notice that much of a speed increase, though. I used a stopwatch and the increase total was only like half a second. Still better than nothing I guess, though.

Size-wise, there's a huge difference, though. Even after deleting the two unnecessary ClrDraw commands at the top of my original code to drop my original program to 623 bytes, your optimizations made it drop to 457 bytes!

Thanks a lot

Yes! It helps quite a bit.

I think that I underestimate the speed of which Axe can produce sprites. This would explain a lot of things.

Looks really cool and fast. :o
I have to learn how to enlarge sprites like that. Enlarging by 2x is easy, though...

Note: I would not recommend using zooming tilemappers, though. As you can notice in the screenshot, I get about 9 fps. After Quigibo optimization, I got 10. If I get 10 with only one sprite, imagine what it would be with 10+

I only needed one sprite to be enlarged. :P

Here's the code I just modified for 16x24 sprites:
Code: [Select]
:.MAGX8
:.I'm too lazy to put in my own 16x24 sprite
:[sprite data here]→Pic1
:[0000000000000000FFFFFFFFFFFFFFFF]→Pic2
:For(Z,10,80
:ClrDraw
:For(C,0,24)
:C*Z/10→A
:{C*2+Pic1}r→E
:For(D,0,16)
:D*Z/10→B
:Pt-Off(B+17,A,E^2 and (C<8) and (D<8)*8+Pic2)
:E/2→E
:End
:End
:DispGraph
:End
Should work, I hope.

Edit: typo

I see that the community wants me to make this thing psuedo-3D.

XD

Try to not make something too large, though, if you do that. If you use pre-rendered map pics your game will get massive very fast and collision detection will quickly reach the 8 KB code limit x.x
