yeah, and first of all fix some bugs, e.g. the figure falls more slowly when you hold down any key.

I don't know if this is bug or not, but just leave it if it is because it's really cool.

prgmA0
.0:
.A
ClrDraw
Text(0,0,"HI
DispGraph
End
Stop
prgmA1
.0:
solve(0,"EA0","VTEMP
prgmLbl "A
Stop
Archive A0 and run A1, and it works.

Erm, that is not intentional in the least and I believe what it is doing is finding the RAM of the program (it isn't erased when archived).

I actually got the idea(code) when I found out that when I forget to put "Stop" on Grammer program, it just "jumps" to next program in line.

In response to continued requests, I have a mini update that has full clipping for rectangles. I hope it works the way you would like it to!

.___. I will say that there are two bugs that I have found and fixed so far for the next update. abs( does not work for negative numbers and in the feature requests thing, the very newest version messes up with solve(0 if the optional arguments aren't used. Well, I will upload that now as a mini update, I guess.

Also, here a screenie of an attempt with grayscale tilemapping


I still need to work on it because there is still some flicker on my actual calc. I am going to experiment with what I have learned from folks like Runer

Okay, so here is an update I cannot remember everything that I have added or fixed, so sorry What I do remember:
Vertical has been fixed. Apparently it is so unused, nobody found that it wasn't working for probably a month or two
Pt-On( and Pt-Change have two more tile drawing methods. Method 6 is now Mask and Method 7 is now Gray. The way the sprite data is setup is like this:
First byte is the first drawn layer and the second byte is the second drawn layer.

For Masked sprites, the first layer is the mask. For the mask, leave pixels off where you want the screen erased. The second layer is drawn over top with OR logic.

For Gray sprites, the first layer is the gray layer. Leave pixels on for gray, off for white. The second layer is the black layer. Leave pixels on for black and off for white. So if a pixel is on in the black layer, it will be black. If it is off in both layers, it will be white. If it is on in only the gray layer, it will be gray.

For gray sprites, you will constantly need to redraw it and display the screen to get the effect (otherwise, you will notice the sudden freeze in gray on whatever frame it is on).

As another note, the screenie is about what you should get on your calc (it is what I get).

Okay, I am still trying to think of how best to do this, but I have started to make a token hook. The token hook simply changes the names of a few OS tokens while editing a Grammer program. If the program you are editing starts with .0:, the token hook will take hold. This also happens if you put that header on the homescreen >.>

If anybody wants to play with this experimental version, feel free.
