So... I got an appvar read from the archive (using files) in my VVVVVV port! The appvar is a 768 byte list and uses the following code:

!If (GetCalc("vVVVSAV",Y0)->V)
Output(0,0,"CREATING SAVE")
Pause 1000
GetCalc("vVVVSAV",768)
GetCalc("vVVVSAV",Y0)->V
2->{L+3}->{L+7}
0->{L+0}->{L+1}->{L+2}->{L+8}->{L+9}->{L+18}->{L+19}
8->{L+5}->{L+14}
48->{L+6}->{L+15}
0->{L+10}->{L+12}
0->{L+11}->{L+13}
Copy(L,V,768)
End
Copy(V,L,768)
{L+0}->A
{L+1}->B
{L+2}->C
{L+3}->D
{L+5}->F
{L+6}->G
{L+7}->H
{L+8}->I
{L+9}->J
{L+10}->K
{L+11}->L
{L+12}->M
{L+13}->N
{L+18}->S
{L+19}->T
{L+14}->X
{L+15}->Y

It works completely and totally!

My problem: I have a 9600 byte appvar (made by another program I made) for the maps. It works in the normal way (without files)

GetCalc("vPIMAP")->U

But when I use it with files:

GetCalc("vPIMAP",Y1)->U

It goofs up the graphics routine and everything that calls that appvar.

Any help?

I haven't really looked through the problem, but here's a little trick you can use to optimize your code a whole lot -

Code: [Select]

{L+0}->A
{L+1}->B
{L+2}->C
{L+3}->D
{L+5}->F
{L+6}->G
{L+7}->H
{L+8}->I
{L+9}->J
{L+10}->K
{L+11}->L
{L+12}->M
{L+13}->N
{L+18}->S
{L+19}->T
{L+14}->X
{L+15}->Y

can be replaced with

Code: [Select]

Copy(L,{E}9CFB,16)

where {E} is the EE key where your comma is on the keypad.

False. First of all, there are alphabetical gaps in those variable names. Secondly, variables are two bytes large and a Copy() won't skip every other byte. Lastly, it's very bad practice to use raw hex values as variable pointers, the ° operator exists for a reason.

Code: [Select]

GetCalc("vPIMAP",Y1)->U

It goofs up the graphics routine and everything that calls that appvar.

Any help?

Remove the useless "->U" and replace all your "U" after this line by "Y1". And don't forget to archive your appvar.

Ah i guess ypu put a Y1 in your pt-on, which is forbidden.
Then, try this instead (sorry, i am on android so i'll post a weird syntax)

Getcalc appvpimap,Y1
Copy Y1,L3,768

Then replace all the Us (the ones i said shoumd become y1s) by L3

Lol, then you have two solutions: either create a temporary appvar with the right size (pointed by U) and copy the archived one in it, or copy 8 bytes of data to a temporary buffer like L3 before each pt-on. For example, if your Pt-On is like Pt-On(X,Y,f(Y1)), you can replace it by Copy(f(Y1),L3,8):Pt-On(X,Y,L3)

Well, I gots this working with Hayleia over IRC! Thanks y'all!

It's crazy slow to make a TMP copy every time you draw. Also, files work form RAM.

They work from RAM but there is no point using them from RAM
And it may be too slow for moving tilemaps but he only draws the map once (I guess) and then only the player moves, so the loss of speed isn't a big problem here.

Great
