[Bug] Room explosion process differs from TH

[MandrakeHorse]

Describe the issue

Whenever machinery explodes from either overuse or an earthquake, the room explosion process does not match what happens in Theme Hospital:

• In CorsixTH, there is no explosion animation and instead, the room instantly becomes destroyed. In Theme Hospital, an explosion can be seen.
• In CorsixTH, if a patient is present in the room, they are immediately deleted (similar to staff). In Theme Hospital, the patient enters a dying state where they collapse to the ground (possibly with a sprite change), get back up, become an angel and fly upwards to heaven.

Steps to Reproduce

1. Load save game attached to this ticket
2. Wait until the Operating Table explodes from overuse

Expected Behaviour

The expected behaviour can be see in this Let's Play: https://youtu.be/VqJeh3i5j1w?t=728

• The machines will have an explosion animation when destroyed.
• When a patient is killed by exploding machinery, they will enter a dying state where they collapse to the ground, get back up, become an angel and fly upwards to heaven.

Additional Information

Lewri: additionally the explode anim being missing I'm merging into this issue (#2553)

They also briefly become a female patient (that's a TH bug though)

There are explosion animations in the TH files for a single cloud, which I guess it spawns in a randomly placed multiple of them on explode. This is probably doable enough, and might be interesting for someone to look at and play with.

The Dr still just instantly despawns (probably because staff have no death anims). Patients currently are told to always die in a corridor. It'd need a code change to let them die in the room during explosions (rather than just despawn)

Sidenote: The explosion animation also appears when firing the bomb weapon in the Rat Bonus Level, so it can be reused once we get around to implementing this minigame:

Have we got any idea of how this animation effect is made specifically, and is anyone interested in replicating it to CorsixTH?

Never saw it in action, but the second screenshot looks to me as 2 explosions. The big smoke spheres likely expanded from small spheres before taking the screen shot.
The small spheres are then relatively younger.

This also seems to happen in the first screenshot, assuming spheres eventually get a darker color.

I'd start with a bunch of explosion animations at random height and random horizontal displacement from some center point as a start. Then shortly after it another bunch of such animations.

Depending on how it looks you may want to adjust things, eg reduce displacement with increasing height.

I am not particularly interested in implementing it.
