Axe Q&A

[MGOS]

Wow, this is exactly what I needed - thanks!

But how can I handle the other possible keypresses? Should I change everything to getkey->K and check the other possibilities with the inData, or can I leave the getkey()?

This Code: Select All | Copy To Clipboard 1 2 3 4 5 6 7 8 9 10 11 12 Repeat getkey(15) getkey->K inData(K,Number-Possibilities)->N if N<9 + N do number stuff elseif getkey(whatever) do other stuff elseif getkey(whatever) do other stuff End End

Or that: Code: Select All | Copy To Clipboard 1 2 3 4 5 6 7 8 9 10 11 12 0->K Repeat K=15 getkey->K inData(K,All Possibilities)->N if N<9 + N do number stuff elseif N=whatever do other stuff elseif N=whatever do other stuff End End

It depends.  What are you using this for?  If this is for a menu or text input, I'd go with getKey, but if this is for part of the main engine for a game I'd go with getKey(#) and make eight of them in If statements.

It's more like an editor, so I think getkey->K is good for this. But if I used both functions, would they still work both fine?

They'd work fine, but I'd stick to one or the other for a more standard appearance.
I think getKey->K is the best solution too.

Good luck with the editor.

Ok I have a feeling I'd be able to firgure this out myself, but it would prolly take a while since I don't remember much from math

Anyway, so I have a projectile flying at (S,T) with an angle, Z.  If Z is zero it faces straight down, 256 degrees, etc.
I have an enemy at, say, (X,Y).  How would I check which side of the projectile the enemy is on (right or left), related to the projectile's angle?

Data(33,34,26,18,35,27,19,36,28,20)->GDB0
While 1
getKey->K
inData(K,GDB0)->r1
EndIf r1

Data(33,34,26,18,35,27,19,36,28,20,0)->GDB0
While 1
getKey->K
inData(K,GDB0)->r1
EndIf r1
Fixed.

tan⁻¹(S-X,T-Y)-Z^256<128 should be true if the projectile needs to rotate in the positive direction.
tan⁻¹(S-X,T-Y)-Ze0 is optimized but returns the opposite.

Good catch.  Thank you!

If you had the X and Y velocity (we'll call A,B) instead of an angle, you could ditch the slow trigonometry and use cross products instead!

How does Axe handle sprites whose lengths are greater than 16? For example, if I had [AA00AA00AA00AA0032BB32BB32BB32BB] would it be displayed horizontally as two sprites, vertically as two sprites, or some other way completely?

[Darl181]

Pt-*() displays the next 8 bytes after the pointer.  So, if you wanted that to display them, one after the other, you would have to display it 8 bytes at a time:
[AA00AA00AA00AA0032BB32BB32BB32BB]→Pic1
.stuff, etc
Pt-On(X,Y,Pic1)
Pt-On(X+8,Y,Pic1+8)

[BlakPilar]

Ahh, okay. So [AA00AA00AA00AA0032BB32BB32BB32BB] is equivalent to [AA00AA00AA00AA00][32BB32BB32BB32BB]?

If two calculators were connected via linkport and both running Axe programs, and 1 calculator wrote 1 into the Port, and the other wrote a 2 into the port, what would each calculator read the port as?  I know the result can be determined by some sort of binary combination of the two numbers but I can't remember which.

Yes.

0

(A or B) xor 3 or equivalently 3-(A or B)

[parserp]

Does axe have buffer support for text? Cause I can't do:

Code: Select All | Copy To Clipboard

1	:Text(X,Y,"Stuff"[sup]r[/sup]
