Dev test: Energy Forms and Changes 1.1.0-dev.4

[chrisklus]

@jbphet, @arouinfar, @KatieWoe, @ariel-phet, energy-forms-and-changes/1.1.0-dev.4 is ready for dev testing. Please document issues in https://github.com/phetsims/energy-forms-and-changes/issues and link to this issue.

Assigning @ariel-phet for prioritization.

General Dev Test

What to Test

• Click every single button.
• If there is sound, make sure it works.
• Make sure you can't lose anything.
• Play with the sim normally.
• Try to break the sim.

Focus and Special Instructions

We've added an alternative algorithm for distributing the energy chunks within their blocks and beakers. It's faster and meant to replace the usual repulsive algorithm on slow devices. We'd like to make sure that it's kicking in when it should on slower devices like Tycho and Jemison, and is not kicking in on normal/fast devices. See the query param below to familiarize yourself with its behavior.

Query params:

To view the alternative energy chunk distribution algorithm (on any device, regardless of speed), add the query param ecDistribution=spiral.

You can add speed controls to the first screen with the query param showSpeedControls. This is useful for testing, but we are not looking for issues caused only by fast forward.

If you're tired of having to manually hold the burners on the intro screen, you can make them sticky with the query param stickyBurners.

General Dev Test Platforms

Who should I assign?

We typically assign the developer who opened the issue in the QA repository.

My question isn't in here... What should I do?

You should:

1. Consult the QA Book.
2. Google it.
3. Ask Katie.
4. Ask a developer.
5. Google it again.
6. Cry.

Here is a gif of how the energy chunks move without the spiral:

Here is a gif of how the energy chunks move in the spiral:

[KatieWoe]

I saw the sim go to spiral once in edge, but upon every other load so far use the default behavior.

[KatieWoe]

Edge also has brief periods of lags and graphical flashes, but overall I would say it is acceptable for the platform. @jbphet let me know if you want further investigation on this.

Windows 7 + IE Performance

• Without ecDistribution=spiral: FPS ~ 11 while chunks float up.
• With ecDistribution=spiral: FPS ~ 30 while chunks float up.

Visually, ecDistribution=spiral is a significant improvement.

Windows 7 + Chrome Performance

• Without ecDistribution=spiral: FPS ~ 55 while chunks float up.
• With ecDistribution=spiral: FPS ~ 60 while chunks float up.

Looks like the bad performance on Windows 7 + IE is due to IE, not Windows 7.

[ghost]

Forgot to mention you, @jbphet.

iOS 11 + Safari Performance

• Without ecDistribution=spiral: FPS ~ 9 while chunks float up.
• With ecDistribution=spiral: FPS ~ 14 while chunks float up.

Without ecDistribution=spiral doesn't actually look that bad despite the low frame rate. With ecDistribution=spiral is a slight improvement.

Feynman (ChromeOS 73.0.3683.32) Performance

• Without ecDistribution=spiral: FPS ~ 5 while chunks float up.
• With ecDistribution=spiral: FPS ~ 7 while chunks float up.

Without or without, the performance is pretty bad.

Feynman is enrolled in the Chrome Beta, so the Chrome version is newer than regular Chrome.

Performance on Chadwick (another Chromebook test device we have) is much better than performance on Feynman. Chadwick is not enrolled in the Chrome Beta.

[ghost]

Checked the following low performance platforms:

• Windows 7 + IE,
• Windows 7 + Firefox,
• Windows 7 + Chrome,
• iOS 9 + Safari,
• iOS 10 + Safari,
• iOS 11 + Safari,
• macOS 10.10 + Safari, and
• ChromeOS

Posted a comment in this issue if I thought there was anything noteworthy.

@chrisklus, @jbphet, let me know if there are any other platforms you'd like tested.

[ghost]

I think QA is done unless @KatieWoe has anything else she'd like to test.

[KatieWoe]

I agree, this looks good. Thanks @lmulhall-phet
QA is done

[chrisklus]

Thanks everyone, closing.
