IndustryTile - substitute tile

[Borg]

Hello.

I have problem with default industry tile animations when I change some tile properties.

// Properties for Industry Tiles of Power Plant
! * 00 09 04 01 07 08 07 09 07 0B 01 08 0C 03 08
! * 00 09 04 01 09 08 09 09 09 0B 01 08 0C 03 08

As you can see, I only replace tiles with does NOT have animation or/and sounds.
When I do so, those tiles are no more animated (smoke, bzz effect etc).

I found following code in property copy:

/* A copied tile should not have the animation infos copied too.
* The anim_state should be left untouched, though
* It is up to the author to animate them himself */
tsp->anim_production = INDUSTRYTILE_NOANIM;
tsp->anim_next = INDUSTRYTILE_NOANIM;

The question is? Can I somehow reenable default tile animations? Doing RTFS it seems
I cannot redefine those 2 vars. But doing more RTFS, it seems that enabling bit1 of propery 11 of tile
should actually do the trick as there is code fallback to defaults..

Okey, after more RTFS and testing I managed to get Power Station tile animation for
spark effect working (with sound!). As for smoke, forget it, this stuff is hardcoded for
built-in Industry.
