How do I put parts of a code as an appvar?

[jacobly]

I'm pretty sure it's like that, just have the second line of hex under/part of the first one.

...
Ok, I was optimizing last night and wrote down a bunch of Q's as I went.

Do the ?/?? conditionals save space in the executable in relation to conventional If loops?  How about speed?

Can they be nested?  like B?(A++5?-1→A),→A works, nvm that

Which is faster: If (commonly true) / If (sparsely true) ?

So it's optimized to put the constants at the end...what if it's like L2+2?  Would a different order influence anything?

1. ? and ?? are just convenience notation, so they are probably the same as If statements.
2. The speed of an If statement depends on what conditionals you use. However, for If / Else statements, the Else is generally faster due to one fewer jump. This is why I generally put the commonly true branch in the else part.
3. L₂+2 and 2+L₂ both optimize to 35388

How do I put parts of a code as an appvar?

lol I was just about to ask that, I need it for some optimizations
does anyone have an answer?

[Darl181]

If you mean something like external levels, you could create a new appvar then copy to it.
Say you have the stuff to be stored to the appvar in L1:
"appvNAME"→Str1
GetCalc(Str1,768)→P
Copy(L1,P,768)
and now you have an external appvar that has the contents of whatever was in L1

Do you mean "run" code in an appv?

How do I put parts of a code as an appvar?

This is extremely difficult to get working, because of the way assembly works.  Assembly code only works at a specific location, if it is moved to anywhere else in memory, it will cause horrible crashes.  The issue with running code in an appvar, is that you need to copy that code to $959D, which is where your current program is!  It becomes a bit easier if your current program is an appvar, but even then it requires custom asm and Bcall knowledge.  I am not an expert on getting it to work, so I can't provide the details.  So the most I can say is try to fit all your code in 1 program, and use a program like Fullrene or Crabcake to surpass the execution limits.

ok so what I meant was, How do I save a level in one of my games as an appvar, and how do I get it into my games main program later? In Axe?

but I figured it out

[epic7]

Problem that's had me stuck for a few days:

I honestly cant find what's wrong with it

The beginning part that works.

Then just :Pt-On(X∕256,Y∕256,P∗8+Pic1) :If B :B−− :End :DispGraph :End

(which works)

[Builderboy]

It would help a lot if you told us what wasn't working.  Throwing a whole bunch of code into a post and asking us what is wrong is not going to help much

[epic7]

Good idea

In the middle section, the guy jumps into the air and freezes. I believe that H gets stuck at 3 even though I have an H++.
At the line,
:1➔P ;works
:Line(X∕256+7,Y∕256,S,T) ;but this only flashes on for 1 frame!

The guy is supposed to move, here
By the time it gets here, H is succesfuly at 2, so it works
(If H>1 is also here)

:If H<15
:Y+256➔Y ;doesnt work
:If θ
:X+256➔X ;but this does, but only 1 time for some reason
:Else
:X−256➔X
:End
:H++ ;This H++ only works once, to get H to 3. Its supposed to take it up to 15, though.
:If Y∕256=48 ;This is if the guy hits the ground early, but not really important right now.
:0➔H➔P➔S➔T
:10➔B
:End
:End

Afterwards, there is

:If H≥15 and (H≤25)

But I obviously cant get that to work since H gets stuck at 3
I don't know if there is something preventing it from changing

[mrmprog]

You may have already tried this, but whenever I get stuck like that, I just slow down the main loop a ton, and then have it display the value of the var in question. Can I see a full download of the source?

[epic7]

I tried exactly that

I can't get to a computer right now, so I'll have to upload the calc file Tommorow. However, the full code is posted above.

[Stefan Bauwens]

In my game I added interrupts.
I put 'it' to 6(slowest speed 118 times a second).
My interrupt label is this:

1 2 3

lbl m text(doesnt matter) dispgraphrr

But this way the grayscale is very pretty but my games goes insanely slow. Am I doing something wrong?

[aeTIos]

Try removing your text?

[Stefan Bauwens]

Nope
It helps a bit i think but moving left and right is really slow and I think it's because it has to draw a part of the map then.
