NEED HELP CREATING THE "DS COMICS PAGE"

[MEGAMAN X]

I am planning on making a game (more of an application) where one could read comics on the DS.
Is there any way to change the picture without changing the room each time? Also, is there a limit to how many rooms or backgrounds I can place in a game? I have placed the .dsgm file of the game at the bottom of the page, so you can check out exactly what I'm doing.

You could just change the background instead of the room. And I dont think theres a limit and if there is then its like really big.

I think a comic reader for the nds has already been made though

[MEGAMAN X]

Do you know how I could change the background?

I've never heard of a comic reader for the DS, what's the name of it.

[memefefe]

I dont remember but I did see it once, It might have been more for manga I cant remember

for the background just make two of them then add an object with no sprite and put a condition for going to next page then add the change background action

I don't think that would work. There is no If background is option, so I wouldn't be able to go back to the previous page when I press the back button.

[memefefe]

Add a global variable called BGNumber or somthing and then in a step event have If BGNumber is equal to 1 set background to whatever the first page is,then continue this for all the backgrounds

now add a button for the next and a seperate one for the back, in them put if tapped set BGNumber to BGNumber +1 or for the back - 1. I havent tried this and I dont know how effective it would be but you can try it

I tried adding variables, but that didn't work either. The first test at the top of the page never crashed, but now the game crashes whenever I push the arrow to turn the page. I added the two .dsgm files of the game,so you could look at it and maybe figure out if I'm doing something wrong.

Okay, so here's how it's done:

To set a variablt by 1 each time you press the right button sprite, you have to Set Variable BG to BG + 1. Not Set Variable BG to + 1. That will only set it to +(positive) 1.

Also, instead of switching rooms, it would be more efficient to Change Background.
So, If BG is Equal to 1: You'd Change Background to Background_1! Or in your case gf1.
And If BG is Equal to 2 You'd Change Background to gf2 and so on.
You can do the same for subtracting one.

There isn't a limit to the ammout of rooms or backgrounds other then the limit of 4MB per application unless you use Nitro libs.

The error you are experiencing is caused due to assigning +1 as a variable - it's an incompatible one.

What you're supposed to do is use BG+1, among other slight mistakes.

I'm adding a re-write of your code, I hope you'll be able to make out what changes have been made. Of course this is really basic code and I would solve those issues differently, but I'm trying to make this as understandable as possible.

GASP! I has been Ninja'd!

Buck beat you to it, Foxi.

[Buck_7]

What does that mean? Your's is probably better than mine i'm guessing.

[Foxi4]

Well, my copy is half the size while retaining the same content, so suck it up, newbies!

Less space used up/less code used = better.

[Foxi4]

What does that mean? Your's is probably better than mine i'm guessing.

It's the intentions that count.

I just thought that nobody's going to help him since the Forum doesn't get much traffic anymore.

[Buck_7]

Hey, actually, It's almost exactly similar!!

The only difference is that the GoToMenu obecjt has an error in it. When you go to Comic_Select, it goes to the room before changing the variable BG to 0.

Well, the most important difference is that the entire interface was simplified to 1 spritesheet.

If you have icons that will all be displayed at the exact same time and you know it will always be so, it's best to simplify things and attach them to one sprite.

Another difference is the mechanism of changing Frames and cutting off functionality whenever Page reaches a certain limit, so that the variable doesn't go ape and so that you don't have to delete and re-create objects which always causes issues.

I would've gone the extra mile and use SPRINTF to generate the page name to load, but that requires a C/C++ Driving License to be understandable. ;P It would allow the user to forget about a whole lot of If statements though...

EDIT: Oh yeah, before I forget. Buck? Don't use Start Animating in step. It's a CPU-consuming Action that re-starts each frame. Setting a frame is much better. It'd be even better if it was wrapped in a frame checker not to switch frames for no reason, but I really didn't feel like adding extra code to it. ;P

Oh, I see. I like it when you guys help, cause I get to see your super efficient code.

I just wanted to practice my abilities to explain.

[Foxi4]

Oh, I see. I like it when you guys help, cause I get to see your super efficient code.

I was a beginner once, like you... and then I took a C/C++ tutorial to the knee and started being a smart-ass.

[MEGAMAN X]

Thanks for the help everyone! It works perfectly now!
If anyone has a favorite comic strips that they would like for me to put into the application I will. Also, if anyone knows a good website where I could find a lot of comic strips, please post the name. Thanks

Foxi, I think you need a bar of soap, so you can clean your mouth out.

[Foxi4]

That... is exactly what my girlfriend's mum told me once, to the word. XD
