- Restored "steam" code to chem grenades to handle grenades that don't have any reagents in them that react i.e. water grenades. (I removed it thinking it was only in there for handling foam reagents, but it seems it has more uses.)
This splashes the surrounding area in whatever reagents were leftover in the grenade after all reactions have occurred.
Fixes#3986
- Foam reagent inheritance fixed:
The trans_to() proc in Chemistry-Holder.dm was calling handle_reactions() every time it would add and remove reagents with add_reagent() and remove_reagent(). I've added a safety flag to both of these procs (and copy_to()) so that trans_to will not call handle_reactions() until it has added all the reagents to the target container. This allows foam to reliably take on the properties of other leftover reagents.
- Fixed a bug in effect_system.dm that wasn't applying reagents from foam to the environment.
- Tweaked smoke to apply reagent effects after it has stopped moving
This was causing huge reagent spam at the center of the smoke cloud as it was spawning, since they were being applied every time the cloud of smoke moved. Also changed it to apply the effects 2-3 times at longer intervals (2 seconds).
- Smoke also only effects tiles in a 3x3 grid now, rather than 5x5.
- Summary:
Chem smoke does slightly less damage (if it contains damaging reagents)
Chem smoke proc calls reduced by 60-70% (significant lag reduction)
Foam works properly again
Foam proc calls reduced by 70-80%
We discovered that most of the problems were were having was because of BYOND passing lists (e.g. SE and UI) by-ref instead of the assumed by-val.
This commit adds dna.Clone() and (UI|SE).Copy() where needed. These should be used where DNA or SE/UI lists are COPIED, otherwise changes made in the reference will affect the real strand.
This change also messes with the gene activation logic.
