Renderer questions and requests

[Joramun]

As I was investigated the code to make a "simple" dialogue system (one that could be embedded in ESB easily)
(ian_scho's is to complicated for me event though it's very powerful), I have a few questions:

1) I couldn't find a function to return the character portrait (as a bitmap).
I find two uses to this:
- Make custom displays of character portraits
- Being able to make alterations to portraits without entirely replacing them with dsb_replace_portrait() using the draw functions

2) Is there a way to override the viewport ? (without overriding the full screen)

3) I see the dsb_fullscreen locks the game. Is there any way to "decouple" the screen drawing from the game locking ?

4) Is the lock done with "dsb_lock()" equivalent to the implicit lock in "dsb_fullscreen()" ?

5) Also, sys_inventory_enter() etc. function are called after the inventory is entered, is it still possible to interrupt/override the inventory screen display ?

[Gambit37]

I'm interested in #2 and #3 also -- I think a full screen, dynamic magic map would be pretty cool...

[Joramun]

Parallax made a fullscreen magic map. I think it's dynamic.

Other question: I'm unhappy, I can't create a dsb_msgzone in a fullscreen bitmap. For some reason, the target I pass is invalid. Also, I don't understand what the third argument (number) is for:

Code: Select all

dsb_msgzone(sheet, next_dialog, number, x, y, width, height, M_ACTIVATE)

DSB complains : dsb_msgzone target is invalid. I'm not even sure it's talking about the bitmap (sheet) or the instance (next_dialog)

Also, once a dsb_fullscreen is rendered without EXIT_ON_CLICK, what's the best way to make the game return to normal (ie. the dungeon view) ?

[ian_scho]

2) Have you tried dsb_add_condition, setting type to PARTY?

I couldn't find a function to return the character portrait (as a bitmap).
I find two uses to this:
- Make custom displays of character portraits
- Being able to make alterations to portraits without entirely replacing them with dsb_replace_portrait() using the draw functions

The reason that character portraits must be passed to dsb_replace_portrait as a string is because there is no (easy and sane) way for me to directly save a reference to an arbitrary bitmap. This also means that any modifications you make to the character portrait bitmap aren't saved, so drawing on it is probably not going to work as well as you might hope, because saving and reloading will ruin anything you've done. If you really want to do this, the best approach might be to create a new bitmap in gfx, pass it to dsb_replace_portrait, and draw directly on it, but you'll have to write code in sys_game_load to ensure that the portraits are properly refreshed on every game reload.

Is there a way to override the viewport ? (without overriding the full screen)

Yes, ian_scho had the right idea. Just make an overlay that covers up the entire viewport.

Is the lock done with "dsb_lock()" equivalent to the implicit lock in "dsb_fullscreen()"

Not really. The game is locked in dsb_fullscreen because an internal loop entirely separate from the game's main loop is running.

This means that:

I see the dsb_fullscreen locks the game. Is there any way to "decouple" the screen drawing from the game locking ?

I'd have to duplicate a lot of the "main loop" code inside of the "inner loop" of dsb_fullscreen. I'll figure out how easy or hard this is.

Also, sys_inventory_enter() etc. function are called after the inventory is entered, is it still possible to interrupt/override the inventory screen display ?

It's possible to block it, with dsb_lock_game(LOCK_INVENTORY). If you want more precise control than this, let me know and I'll see if I can come up with something.

I'm unhappy, I can't create a dsb_msgzone in a fullscreen bitmap. For some reason, the target I pass is invalid.

The target is invalid because dsb_msgzone is expecting a subrenderer bitmap. I never thought that someone would try to use it in a full screen bitmap.

Also, I don't understand what the third argument (number) is for

It's a zone number. This allows you to override/replace zones by specifying an existing handle. It also allows msgzones to have more information about where you clicked, because the zone number you clicked is passed as the msg's data parameter. If you don't care about any of this, just keep incrementing the number for every new zone.

Also, once a dsb_fullscreen is rendered without EXIT_ON_CLICK, what's the best way to make the game return to normal (ie. the dungeon view) ?

Return true from any of the functions you pass it to drop back to the game.

[Joramun]

It means I'll have to create buttons on my bitmap with my own tiny Lua hands.

Also, Ian's Scho's idea is cool but is it possible to make said buttons and work on the bitmap that is passed to the dsb_condition() function ?
I guess than answer is the same than with a full screen overlay: yes but without dsb_msgzone()

EDIT: Ok, I've tried to create a button using dsb_fullscreen's click_func argument but it doesn't accept extra arguments aside from mouse parameters...
I think I'll have to create some complicated loop instead

EDIT 2: I still have problems with the local keyword it seems
Now I have a perfectly working, simply customizable DIALOG SYSTEM

[Mon Ful Ir]

Ooh! Would you mind sharing it, Joramun?

[Sophia]

It means I'll have to create buttons on my bitmap with my own tiny Lua hands.

It's better this way, really. The main purpose of dsb_msgzone is to send a message to something based on where you click. This works fine for a subrenderer, because you send messages to the object instance that the subrenderer is associated with. For a full screen thing, though, you'd have to create some inst to receive the messages, and it gets a little weird.

Also, Ian's Scho's idea is cool but is it possible to make said buttons and work on the bitmap that is passed to the dsb_condition() function ?

In that case, what you are really wanting to do is create clickzones over the viewport. This is obviously possible to do (as the engine does it all the time) but you can't dynamically create arbitrary ones. Would there be some use in being able to do so?

[Mon Ful Ir]

It would probably have some uses in creating custom plot/dialogue screens, shops, taverns, and so on?

[Gambit37]

Yes, yes, yes, gimme some code, I need all the code, bwaaaaa ha ha ha ha bwap bwaaaaaghhh...

[Joramun]

Copy these into the corresponding files.
Obviously, it's not finished. It's just a simple example of what can be done with DSB in a few tens of minutes of coding.

Actually, I was just joking for now Thank you though

[Joramun]

Try it instead of joking . You might reconsider and continue all your project in DSB instead

Ok. Let me look into RTSB and what I can do for RTC mechanics translation
(besides, this tool badly needs to be cleaned of its dust)
