It works fine but now that I got into the habbit of making my own battlebacks I was wondering if it was possible to edit this script to allow 1024x640 size battle backs, currently when I use them the background shifts down right and doesnt strech properly, I was hoping to make high res battlebacks so it wouldnt look so pixelated when it zooms in.

Sorry the comments are not in english v_v

I am starting to learn this but im still doing basic window and cms tutorials, I have no idea what to fix in this script or even if its possible.

[Fantasist]

I've been trying to do the exact same thing for the exact same reason, but I couldn't figure out the numbers in the script. They're hard-coded for the default 640x320 resolution. I should try REALLY hard yet again, or someone more experienced should do it for us noobs -_-

[Blizzard]

Mess around with the zoom factors, that's what needs to be changed. i.e. increasing the factors by 100% will require 1280x640 sized backgrounds.

[Mightylink]

so basicly just double all the zooms?

[Blizzard]

Not double, halve them. o.o Sorry, my bad.

[bnecitizen]

When I try running the game with this script, I get an error.

Script 'Battle Cam' line18: NoMethodError occurred.
undefined method'[]=' for nil:NilClass

Why is this happening?? Such a shame

[KK20]

Holy crap, someone threw a Phoenix Down here!

What RM engine are you using? I believe $imported is meant for VX or VXA.

I'm using RMXP, is $imported in the script?

Edit: Nevermind  

So the script is not for RMXP? just VX and ACE?

[KK20]

I forgot if SDK used that $imported gimmick (never used it, never studied it). After actually researching, it seems this was built with RMXP in mind. Just curious, have you tried deleting those $imported lines?

[bnecitizen]

Yes I just tried to delete the line that use imported, the script then works, but i dont think it works as well as it should. Its quite dramatic and strange.

actually my RMXP scripts use them as well:

($ace_script ||= {})[:ace_stuff] = 1.00

I use it to tell if the script needs to be put above or below another script and for if then statements, etc...
