Try this.inst.curFrame instead.

Hah! I swear I tried that and it didn't work, except now it does. Thanks!

However, my original question still stands. In the event that it is needed, how does one use inst.inst?

I'm writing a behavior that works with sprites. The behavior needs to access the sprite's curFrame object. In reading the docs, it seems the way to get to this is via inst.inst. However, when I try to access this.inst.inst, it says it is undefined. Can anyone tell me what I'm missing?

Thanks!

You might check official drag&drop behavior.

Thanks for the tip. I went all through that code a few times, but I can't see what it is you're indicating.

I did find a purely JavaScript way to do it:

if (typeof cr.plugins_.Spritefont2 == "function")
	if (cr.plugins_.Spritefont2.prototype.isPrototypeOf(this.inst.type.plugin))[/code:11xuxh4b]
That works well enough, but it's kind of clunky.  I'm hoping there's a C2-specific approach that's more direct.  Something like [i]this.inst.type.plugin.id[/i] would be a gem.

I'm writing a behavior that needs to adjust its behavior for different plugins. So I need to be able to check which plugin the behavior is attached to. But type.plugin doesn't seem to have any properties that could be used to identify it. I suspect I'm missing something obvious, but I've been all through the docs and can't find anything.

Does anyone know how to get the plugin id or otherwise identify it?

Thanks.

TrickyWidget : It's quite elegant already! I'll wait to see how it evolves, but it will eventually be a nice supplementary tool to c2's arsenal.

Thank you! It's nice to hear that it's shaping up to be a useful contribution.

Yeah, that's it!

I really like Configure and Configure+ solution.

Keep it going!

Just one more thing, If your plugin is called Twixt it should have same name in C2 (for now it shows up as Tween)

Thanks! Glad I could help.

The "Tween" name inside C2 is actually on purpose. I wanted a name that was consistent with the rest of the design experience. Texts are called Text and sprites are called Sprite, so similarly I thought tweens should be called Tween.

Just posted 0.3, which adds a condition to check the state of the tween.

It's quite nice, I like it.

Easy and simple.

One thing - could you add an action to set "two values" for target. For something like

Target X - mouse.X

Target Y - mouse.Y

Besides that it's nice simple plugin.

Thanks!

I just overhauled the configuration actions. I realized that trying to set the tween properties individually would break things most of the time (oops), so I moved everything into two actions. There's "Configure", which is just like the editor properties. Then there's "Configure+" which allows one to set everything individually and from expressions. I think that's what you were looking for.

I also re-did the expressions to make them more meaningful.

Thanks for the feedback!

The forum doesn't allow attachments with the c2addon extension.

Hey, folks. Here's my first go at the SDK. I needed a tween that could scale sprite fonts, and decided I wanted to take the code a different direction than LiteTween, so I wrote my own.

Twixt 0.53

[attachment=0:1fb7oug5][/attachment:1fb7oug5](This is packaged as a c2addon, but this forum doesn't like that extension. Just rename it to Twixt_0.53.c2addon for drag-and-drop install.)

Twixt is optimized for efficient, linear tweens. Easing is not supported. It can tween position, size, scale, angle, opacity, and Sprite Font scale.

Note that tweening Texts is a bad idea! WebGL handles non-bitmap fonts in a very inefficient manner. If you need to tween text, make sure it's a Sprite Font. I recommend using Sprite Font Generator and SpriteFont+ to make them as painless as possible.

Also note that this is a beta preview. Anything may be broken or become broken at any time. Use with caution! (The 1.0 release should be forthcoming in the not-too-distant future.)

If you find any bugs or have any suggestions, just let me know!

Thanks.

Docs

Most of it should be self-explanatory, but here are some details.

Scale

When scaling a sprite, the internal scale system is used as if the SetScale action had been called. When scaling other objects, the basic width and height properties are used and their start values are used as scale factor 1.

Expressions

StartA - Start value for position X, size width, scale factor, angle degrees, opacity percent, or font scale.

StartB - Start value for position Y or size height. Ignored for scale, angle, opacity, and font.

EndA - End value, as above.

EndB - End value, as above.

State

Start - Tween is stopped at the start position.

Forward - Tween is running from the start to the end.

Paused - Tween is paused between the start and end positions.

Reverse - Tween is running from the end to the start.

End - Tween is stopped at the end position.

Changelog

08/09/2014 - 0.53 - Fixed tweening only Y or height with unchanged X or width

08/08/2014 - 0.52 - Fixed scale of flipped/mirrored sprites

08/08/2014 - 0.51 - Fixed scale reverse end detection

08/08/2014 - 0.5 - Changed debug tweened and state values to their text equivalents (instead of their constant index)

08/07/2014 - 0.4 - Added "scale" as a property to tween

07/30/2014 - 0.1 - Initial release

It is possible to call an action from a behavior. Even call an action/expression/condition from other plugin/behavior.

Thank you for the response! It was actually that very code that I examined from a previous post that lead me to the code I had.

It seems my problem was that I was trying to affect the instance in behinstProto.onCreate. I have no idea why that doesn't work, but when I move it down into behinstProto.tick it's now behaving as expected.

Thanks again!

OK, in the docs I found this:

[quote:1u90lmv3]inst.inst

In behavior instances only: this is the reference to the object instance your behavior should modify.

Which sounds like it would apply to what I'm trying to do. So I amend my code to:

cr.plugins_.Spritefont2.prototype.acts.SetScale.call(this.inst.inst, 0.5);[/code:1u90lmv3]
But that gives me:

[quote:1u90lmv3]Uncaught TypeError: Cannot read property 'characterScale' of undefined

Still searching...
