This is the article of a development build of Skyscraper Simulator.
It has been confirmed a good-faith contribution to the Skyscraper wiki.

This is an update to the previous build, which fixes a number of major issues found. I've also fixed the 64-bit Linux package, which was missing an updated libSBS.so file.

The deletion of objects was broken in the previous build, due to issues recreating the collider. I also found that Shaft and Stairs objects were using wrong data when removing themselves, which could've caused malfunctions.

On Windows, a graphics corruption happened when doing a reload (ctrl-r), which has been fixed.

Elevators no longer load idle sounds (and some others) on start, they wait until the first play, which should save some memory.

The FindWithCase C++ function was fixed, which could've been causing issues in the script interpreter.


Changelog for this build:
-fixed console reporting of missing files
-added sound unload function
-don't load main elevator sounds on first loop run, load right before playing
-if sound is disabled in frontend, sound in engine should also be disabled properly
-object removal functions in Shaft and Stairs objects were using a wrong index value
-reworked object array method for Door objects, in stairwell and shaft objects
-reject mp3 files on load
-fixed FindWithCase function
-reworked and cleaned up call button code
-fixed an issue in call button processing that prevented engine callbacks from being removed
-don't run elevator checks if elevator is disabled
-disable objects when disabling elevator
-don't try to create a collider scenenode if it already exists
-made a proper fix for an issue involving graphics corruption on Windows after a reload. The viewport needs to be updated properly on a reload.
-SBS should call Prepare() on engine start, not frontend

also a quirk fixed from the last build:
-update LastHitMesh code, to get the name of the collider node's parent (the mesh), instead of the collider node's name

Windows XP is still supported, and Visual C++ needed a special build option for XP to work.

For this build, I rewrote the GIF detection code, and so now transparency should work fine in all situations. I had found a major issue with it, which caused issues in some GIF files. I've noticed some speed improvements due to the switch from Visual C++ 2010 to 2015 on Windows.

I've added support for sim objects to be able to switch parent objects, and this is a major change. Due to that and some additional work, you can now move models (such as couches) into elevators and transport them to other floors. This didn't work before, since the model would still be a child of the original floor it was created on, but now it'll switch to be a child of the elevator that it's pushed into, and then will switch to the related floor it's taken out at. I also added support for carrying models, which you can do by moving close to the model and pressing the "C" key, and then you can move it much more easily. You can drop it by pressing the "C" key again. What happens with this, is that the model switches it's parent object to be the camera instead of the floor/elevator it's on, and then then you drop it, it switches it's parent back to the object you drop it onto. You can see this in action in the Object Manager window, where when you pick up an object, it'll appear underneath the "Camera" entry, and when you drop it, it'll be removed from that and appear under the object you dropped it onto. The Console window will also report the parent changes. I've already had fun playing with these features. I've resized the couches to be more realistic, and they fit more easily in the Triton Center's elevators, especially the freight elevator. If you need to rotate a couch vertically to move it more easily, you can do that using the Object Manager window (the Move button). This should give you a good idea on the direction the simulator's going, and it's needed a lot of internal work like this for advanced things to become possible. Previously this feature would've been hard to make, but after adding the parent switching support, it became possible and easy.

Internally in the C++ code, I've switched entirely from "c-style" casts to better functions that use the static_cast and dynamic_cast functions, and also switched from "c strings" in function parameters and returns to STL strings (std::string), which results in the code being much more easy to read, and easier to work with. The older code (which mostly from the CrystalSpace days) needed to be cleaned up, since it was getting too messy. So basically, for people beginning to tinker with the source code, these changes and other ones I've made should make things easier to understand and work with.

I finally found the cause of the Bullet collider bouncing issue on 32-bit Windows, and it had to do with DirectX forcing the whole app into low-precision of numbers, which caused Bullet and Caelum to have serious problems. I had put in a partial fix for the bounce, but found that I had it turned off in previous builds, and so it wasn't being used. I've now prevented DirectX from doing that, and so that issue is fully resolved now. This only happened on 32-bit Windows builds, and when only using DirectX.

I added a Sky Control dialog, which lets you set some of the Caelum parameters, such as location and date/time. I'll be adding to this in the future. I also added the "Coordinates" and "DateTime" global commands in the script language so that you can set these on startup (previously they could only be set in the related Caelum script, data/caelum/sky.os). I still need to add a command to set which direction is north, so that the sky will be rotated properly, if that's possible. I rearranged the buttons on the main control panel window to look more cleaner. The Triton Center building has been positioned at it's fictitous location in downtown Chicago with these options, and I also set the startup date to be 6/23/2015 (my birthday). The Glass Tower is positioned around it's fictitious location in downtown San Francisco, and the startup date is the release date of the movie it's from, the Towering Inferno, which is 12/20/1974:

I've been fixing the main functions to properly work with files within mount points (from the Mount command).

The Bullet colliders for 3D models are now centered properly, and the models are now positioned correctly depending on their scale multiplier.

Changelog:
-set location and date/time for Triton Center and Glass Tower buildings
-added Coordinates and DateTime global options
-resized couches to be more realistic
-model offset needs to be adjusted according to the scale multiplier
-for models, box colliders are now centered properly, and use a separate scene node to make it work
-SBS now calls a cascading init on all objects from the Start() function
-renamed any standard object runloops to Loop()
-renamed Sound's Loop() function to SetLoopState

-OgreBullet should be checking for existence of resource group and loaded names directly instead of keeping a file-based existence flag. This fixes an issue where debug colliders (F7 key) would not enable when reloading a building.
-camera object needs to run loops of attached models
-camera needs to run NotifyMove and NotifyRotate functions, to properly update carried objects (child objects)

-switched from c-strings to std::strings for function parameters and return types
-DeleteObject function can delete generic object directly, instead of recasting
-added new ConvertTo function to Object
-added template-based IsType() function to Object
-removed object's "raw_object" value, which is no longer needed due to previous change

-consolidated camera's mesh hit beam code into main SBS object
-code cleanups
-added support for picking up models
-mesh HitBeam function should be converting direction to remote Ogre value, without a rescale
-objects can now report if they are global objects (children of engine object)
-added ability for non-global physics-enabled models to be moved into elevators, and to move along with the elevator, by dynamically changing parent object of model from floor to elevator, and vice versa
-added Shaft, Stairs and Model runloops
-added functions for dynamic removal/addition of models
-added ability for objects to switch parents
-IsInElevator function now optionally sets CameraOffset value
-added check for model's physics state
-added debugging options file for Visual C++
