Story Builder 15 uses 100% of the cpu all time

[carrott]

On XO-1.5 running Build 861 10.1.3-au2
Start Story Builder
Start terminal
Run top
Observe 100% cpu consumption by Story Builder

This is bad because it will consume the battery faster while the laptop is awake and prevent the laptop going to sleep.

In fact, it is how games work. They all time do something, e.g., play animations...

Does v15 have more cpu consumption for you than previous versions?

[alsroot]

Hmm.. I found that it doesn't stop processing on the switch to another activity.

I'm setting to keyword to "sugar-love".
Would be useful to stop processing pygame loop on if activity is inactive.

[carrott]

100% cpu to do nothing doesn't seem like best practice. There are no animations, it's just sitting there doing nothing.

We need to compare to older versions and other pygame based activities and see what can be do to relief cpu,
previous versions of history builder run fine iirc.

some pygame mod should be involved.

Gary, has made imporvements to overall pygame performance, worth take a look.

I've also drop down FPS to 20 in order that animations run faster.

Replying to RafaelOrtiz:

This is on latest version on ASLO, the crucial error to tackle is the aforementioned by alsroot.
