I guess these were here earlier when there were 'active' conditionals,
but then I removed those, so now they look weird next to the 'i != j'
conditionals, so I'm removing them.
These would be of the form
if (cond1) { if (cond2) { if (cond3) { thing; } } }
which is really annoying to read and could've been written as
if (cond1 && cond2 && cond3) { thing; }
so that's what I'm fixing here.
There will be another commit later that fixes this but in places related
to blocks.
Not sure why this function is here. It makes sense if you know that the
game will only do certain moving platform things if you already have a
moving platform in the room, however apparently this function has
absolutely nothing to do with it.
This function's sole purpose was to make sure obj.nentity was in sync,
and that obj.nentity-1 pointed to the last 'active' entity in
obj.entities. But now that obj.nentity is removed and we use
obj.entities.size() instead, it is no longer necessary.
In the previous commit, if an if-statement consisted solely of checking
the active attribute of an entity, I temporarily changed it to 'true'
and put a comment to remove it later, because it would add too much
noise to unindent everything in the same commit.
This removes the variables obj.nentity and obj.nlinecrosskludge, as well
as removing the 'active' attribute from the entity class object. Now
every entity you access is guaranteed to be real and you don't have to
check the 'active' variable.
The biggest part of this is changing createentity() to modify a
newly-created entity object and push it back instead of already
modifying an indice in obj.entities.
As well, removing an entity now uses the new obj.removeentity() function
and removeentity_iter() macro.
Ok, once we switch everything over to not use the 'active' system, it's
easier to read removeentity(t) than it is to read
entities.erase(entities.begin() + t).
This moves the setenemyroom() function onto the entity object itself, so
I can more easily change all 'entities[k].' to 'entity.' in
entityclass::createentity() later.
Additionally, I've had to move the rn() macro from Entity.h to Ent.h, or
else entclass::setenemyroom() won't know what it is.
This moves the setenemy() function onto the entity object itself,
instead of having to give the indice of the entity in obj.entities. This
makes the code more object-oriented so later I can simply change all
'entities[k]' to 'entity.' in entityclass::createentity().
This changes something like UtilityClass::String to help.String,
basically. It takes less typing this way, and is a neat effect of having
global args actually be global variables.
This commit removes all global args from functions on the entityclass
object, and updates the callers of those functions in other files
accordingly (most significantly, the game level files Finalclass.cpp,
Labclass.cpp, Otherlevel.cpp, Spacestation2.cpp, WarpClass.cpp, due to
them using createentity()), as well as renaming all instances of 'dwgfx'
in Entity.cpp to 'graphics'.
Previously, in tower mode, being inside walls would just kill you, unlike
being inside walls outside tower mode, which was somewhat confusing.
Also, spikes behaved differently with regards to invincibility, being
unsolid in towers but solid outside them.
This does not change the behaviour of the "edge" spikes in towers.
This fixes a bug where warp lines created through createentity wouldn't
work without there already being a warp line present in the room as an
edentity.
Yikes. Somebody brought this to my attention, I didn't even remember that I'd written it. "Spa" or "Spastic" is kind of a south park esque slang term that used to be pretty common in Ireland, which I used without even thinking about it. It's definitely not something I would say anymore, 10 years on, and it's something I shouldn't have said at the time either. I'm sorry :(
(somebody on twitter was asking me about how much cleaning up of the source code I did before launching this. I think this commit kinda answers that)
* Add entity type attribute checks to getcrewman()
This means that the game is no longer able to target other non-crewmate
entities when it looks for a crewmate.
This has actually happened in practice. A command like
position(cyan,above) could position the text box above a horizontal warp
line instead of the intended crewmate.
This is because getcrewman() previously only checked the rule attributes
of entities, and if their rule happened to be 6 or 7. Usually this
corresponds with crewmates being unflipped or flipped, respectively.
But warp lines' rules overlap with rules 6 and 7. If a warp line is
vertical, its rule is 5, and if it is horizontal, its rule is 7.
Now, usually, this wouldn't be an issue, but getcrewman() does a color
check as well. And for cyan, that is color 0. However, if an entity
doesn't use a color, it just defaults to color 0. So, getcrewman() found
an entity with a rule of 7 and a color of 0. This must mean it's a cyan
crewmate! But, well, it's actually just a horizontal warp line.
This commit prevents the above from happening.
Resizing the vector does the same thing that the loops did, it changes
the size for the vector and initializes it with default-constructed
elements (or 0 or its equivalent for POD types).
Where a specific value is needed, it is set with the second
parameter of resize().
