[PLUGIN] Sprite Bank

The new version of sprite bank had been released named instance bank.

Sprite Bank

(update:2012/05/11)

To save some properties of sprite instances(save instances into bank), then create instance and set these properties(load instances from bank). A kind of serialization of sprite instance.

The chart of how to use it is -

<img src="http://i1081.photobucket.com/albums/j352/rexrainbow1/file-6.png" border="0">

"Action: Save instances": saving properties of instances into bank

"Action: Load instances": create instances and set properties from bank

"Expression: BankToString": transfer bank to JSON string

"Action: Load bank": transfer JSON string to bank

The saved properties are

• inst.x
• inst.y
• inst.width
• inst.height
• inst.angle
• inst.opacity
• inst.visible
• inst.cur_frame
• inst.private variables
• inst.layer
• inst.cur_animation.name
• custom data (*option)

Example

For advance user, sprite bank provides calling function plugin when save/create instance. (See test_sprite_bank_adv.capx in example) It can do some custom actions like save/restore properties in behavior.

On saving instance, put data into return[name].

On creating instance, get data from prame(name).

So you can save the speed of bullet behavior then restore it when created.

Actually, the string of callback not only a function name, but also a command used in "action:execute commands", so you can put some parameters in the string.

Wow Thanks!!! Im not sure what to use it for though? What does it save a sprites position or just its existence?

God bless Rex ^^

The plugin is to save the position(and some other porperties).

Ahh cool, So for like rpg's you could save the exact position then on return of game load that position?

smitchell

Yes, it can do that (save the exact position then on return of game load that position).

Do I miss any important property of sprite?

Do I miss any important property of sprite?

Flipped, mirrored perhaps?

Thnaks, I will add these.

I check the "Flipped, mirrored" in sprite plugin. It seems to use

• (width <0):mirrored
• (height < 0):flipped

So current sprite bank can record these two properties by saving width and height.

Ah ok.

Honestly I think I liked it better when you had to go by angle.

Well for platforms anyway.

Uh, making plugin is interesting.

Ooh i see why this one is better suited to making the level editor..

Does this save the sprites into local storage? Or do i need to save the sprite bank locally separate?

smitchell

Using "Expression: BankToString" to transfer bank to JSON string, then save this string into webstorage.
