In the vast majority of cases (i.e. when Gravity::Exchange is indirectly called from BeforeSim), the input is cleared to zeros anyway, so it's less work in Exchange to actually just exchange the old input with the new one than to copy the new one into the old one.
Also make gravity functions private in Simulation.
Aka episode 29743 of game mvc being a joke: Happens since 74386631e0, where GameModel started being destroyed after GameView. The problem is that GameModel assumes that GameView is still alive and tells it to stop rendering the simulation on another thread, and expects it to acknowledge this request.
This fixes two kinds of crashes: the one where the value passed is not possible to convert at all to the type of value expected (e.g. expect unsigned integer, get point), and also when it is possible, because the difference is only in signedness (e.g. expect unsigned integer, get signed integer). Both cases crash since 8552aafbce, where the handling of the former case got removed and accidentally never got added back, and the handling of the latter changed from converting everything to strings and working from there to converting directly between floats and numbers, disregarding signedness.
Broken since 02b679aec3, where GameView started popping everything above itself before popping itself. The problem was that LSI would get destroyed before GameView did this, but popping Lua windows needed LSI to be alive still.
Broken since 00ec4e0754, when the Perform callback was added. It's a bad idea to pop return values that never got pushed because the function that was supposed to push them threw an error.
Broken since 06e2836726, which added LuaSmartRef. That it had absolutely not followed the rule of five at all didn't use to be a problem because it had only ever been in vectors that got resized only once throughout the lifetime of the program >_>
This is intended to support selection-time configuration the way PROP and the custom life tools do it. Indeed, they now use the infrastructure this commit adds to implement their own configuration actions.
Broken in ff4500620e, where the code that constructs DecorationTools got moved from GameModel::BuildMenus to GameModel::InitTools. BuildMenus used to run fairly late, while InitTools is run fairly early, before GameModel's view member is initialized. This wasn't a problem before f52e047037, since which DecorationTools access Renderer through GameView, rather than directly.
Views would invoke c->Exit() upon closing themselves, which would close them but not delete them. The controller would then be destroyed, fail to close the view because it wouldn't be the window on top, and skip destroying it in fear of something worse. This behaviour was introduced by c2f8a7df25, fixing something indeed worse: views would be destroyed while they were still in use by ui::Engine, sitting somewhere on the window stack but not at the top. In other words, the problem was (and is) that the terms of ownership of views between controllers and ui::Engine are unclear.
This commit effectively undoes that earlier commit and tries a different approach: when something is closed, close everything above it. This seems a correct thing to do and also allows controllers to unconditionally take care of their views. Prepare your popcorn though.
This fixes a bug where the stamp browser would stop rendering stamps if it was previously closed "too quickly", which turned out to mean that it was closed before all stamps had finished rendering, and thus ThumbnailRendererTasks belonging to LocalBrowserViews indirectly through SaveButtons would get stuck in a queued state, preventing other SaveButtons from starting their own ThumbnailRendererTasks.
Namely, when any dimension of the underlying particle area is divisible by CELL. Importantly, this includes "normal" saves (as opposed to stamps), which take the entire simulation area, making them impossible to load.
Broken by c2bb777212, where RectBetween(topLeft / CELL, bottomRight / CELL) was rewritten to RectSized(pos / CELL, size / CELL), which is not equivalent. This commit also neglected to add TopLeft() and BottomRight() to Rect. Incorrectly fixed by 6a903ed132, where RectSized(pos / CELL, size / CELL) was rewritten to RectBetween(pos / CELL, (pos + size) / CELL), which is also not equivalent.
Should fix dialog coming up when typing / on some Brazilian keyboards, which use Alt Gr + q to type a /. Apparently this also acts as if Ctrl were held.
The save's blockSize was set one cell too short, so extend it by one (by using RectBetween). This fixes a crash when serializing save data that had particles outside its range.
This is fine, there's no particular benefit to hiding it when they are focused. I did find it annoying that the cursor got a bit tangled up with the placeholder text though, so I moved the text a bit to the right.
This leaves one non-C++ TU in the entire codebase: Cocoa.mm is Objective C++ and is only compiled on MacOS, where it's used for clipboard integration. This too will go away when we move to SDL3, which has a proper clipboard API.
Namely, when those rectangles are not drawn in a top left to bottom right corner order. Broken by a26544ba95, which neglected to port the rectangle normalization logic from Simulation::ToolBox.
This makes the task of deciding which tool goes in which menu easier (GameModel::BuildMenus). Due to changes in the order tools are added to menus, the sign/sample/prop tool triplet now comes before custom tools, and the custom life creation tool comes before custom life element tools, which I think is fine.
This mimics sim.walls.* rather than elem.*_PT_*. The latter is fine because element identifiers follow the *_PT_* pattern, but tool identifiers don't, so they'd be a pain to tell apart from the rest of the API.
This was because element tools associated with Lua elements were reallocated every time their properties changed. They are now properly updated instead.
This is still a mess and I don't like it at all.
Don't just set the .type of struct Particle to 0, kids. Code tracked back to the times from before git; already present in b0ea52690b, the initial commit.
Reproduce with
sim.clearSim()
elem.property(elem.DEFAULT_PT_DMND, "Update", function(i, x, y)
local ni = sim.photons(x, y)
if ni then
if not sim.partProperty(ni, "vx") then
print(x, y)
assert(false)
end
end
end)
local i = sim.partCreate(-1, 100, 100, elem.DEFAULT_PT_NEUT)
sim.partProperty(i, "vx", 0)
sim.partProperty(i, "vy", 2)
sim.partCreate(-1, 100, 100, elem.DEFAULT_PT_DMND)
sim.partCreate(-1, 100, 102, elem.DEFAULT_PT_PRTI)
sim.paused(true)
sim.framerender(1)
Though if done this way, it's actually a photons corruption.
Render mode checkboxes each control multiple bit flags, but they would fully unset all bits they control, even if they shared flags with other render modes (which they always do). This would cause more things to turn off than intended when deselecting options, and all other checkboxes would appear unchecked. Now it will recalculate render mode based on what's checked instead.
Air display mode checkboxes are supposed to act as radio buttons, but it was letting all air modes be selected at once. They are mutually exclusive because only one display background can be drawn at once. Now, they act as exclusive radio buttons again.
