animation api or maybe another option?

Solar2D General Questions/Discussion
#1

Hello.

I was browsing through the DOCS. I noticed there is nothing to program precise animation for display objects. Or did I miss it?

Basically what Im trying to do is take 2-3 images and have them animate like a vortex from the center of the screen outward…

I dont have any code yet because I cannot find in the DOCS the best way to start this. Like I said, there is no animation api calls, or am I wrong? Please help me. I feel like I hit a dead end with this issue.

I was going to buy particle candy or particle designer and see if I can do it with one of those options, but I am repeatedly told that you cannot make particles “clickable” in any way. Im just not sure what to do - Once again, I want to take a series of images and make them animate from the center of the screen outward, starting at a scale of 0 and ending with a scale of 1. Same for the alpha. Picture a vortex moving outward instead of inward. please advise. :unsure:

Hi Joe,

From your description of going from scale=0 to 1, and same with alpha, it sounds like the transition library is what you need.

Hrm…I already saw that page in the Docs but am unsure about if it will do what I need.

I also found this - http://coronalabs.com/blog/2014/01/07/tutorial-moving-objects-along-a-path/

Am I wrong in assuming the above link is the correct way to start? Please advise. Many thanks.

Hi Joe,

If you’re only going to need 2-3 images, and you don’t need any kind of point-specific interaction on those images, then the basic transition library should work fine. However, if you want to create some kind of particle-based vortex where each particle can be tapped/touched individually and trigger a response, I believe you’ll need to use a particle generator tool.

Thanks Brent. You said  - “if you want to create some kind of particle-based vortex where each particle can be tapped/touched individually and trigger a response, I believe you’ll need to use a particle generator tool.”

This is exactly what I am trying to achieve…

Okay. So now I need to know… A particle generation tool such as? Can you give me a good suggestion? I already spoke to the folks that make Particle Designer and they told me that I cannot achieve my goal using their app (Particle Designer). So, can you suggest an app/plugin?

Thanks again for the posts. Much oblidged. :slight_smile:

Hi Joe,

As you learned, emitters built into Corona via Particle Designer do not yet support tap/touch interaction on individual particles.

There are two other particle tools that I know of, and they might handle what you need:

  1. CBEffects (free and open-source): http://gymbyl.com/programming/cbeffects.html

  2. Particle Candy: http://www.x-pressive.com/ParticleCandy_Corona/

Hope this helps,

Brent

Thanks for the links. Have you ever used particle candy to do anything similar to what Im trying to do? Or have you ever seen it done? If you or anyone else can confirm that Particle Candy can achieve what I described in my first post, I will gladly buy it right now. Either way, I appreciate the links. Thanks again. :wink:

Hi Joe,

I suggest that you contact the author(s) of these tools directly and describe what you want to accomplish. I haven’t used them for the specific task that you describe.

Take care,

Brent
