Release notes

This sprint we’ve fixed a few crashes, improved on the gamepad support for Android, and added some physics fixes.

The collision object now has a property bullet, that allows you to enable continuous collision detection. It is only supported in 2D physics.

Our gamepad system now supports reading raw input from connected devices with an unknown identifier.

WIP

We’re continuing working on our editor/pipeline plugin support, and we have released a first alpha of the Rive extension.

Also, we’re currently working on an asset cache system for Bob. This will help reduce long build times for certain assets (i.e. compressed textures).

Was an example ever posted somewhere for this feature / it explained what it’s actually supposed to do? I tried to get it to work on the beta build and posted on the thread there too about it. The “continuous collision detection” didn’t seem to work both by manual movement of collision objects and by using physics forces to move collision objects.

Sorry, I missed this. I will take a look this week.

This is from the (slightly strange) Box2D docs:

bullet

bool b2BodyDef::bullet

Is this a fast moving body that should be prevented from tunneling through other moving bodies? Note that all bodies are prevented from tunneling through kinematic and static bodies. This setting is only considered on dynamic bodies.

WARNING

You should use this flag sparingly since it increases processing time.

Getting an issue with imgui. This is the Build Errors when building in Windows 10. I don’t actually use imgui in this project, I just have it fetched as a dependency.

(etc)

I’m not exactly sure why the error occurs. We’ll have to look into it.

Since you add it as a dependency, we build the engine for you. So in that sense you’re “using it”.

Yes, understood. Was highlighting it in case it helps narrow things down (i.e. none of the imgui functionality is actually used, only whatever happens in the dark magic of engine building).

Please report this to the extension-imgui repo!

One of our devs has changed to 1.2.186, and his work now seems to not being compiling for me (1.2.182). It seems like the collision objects are causing an issue?

I can’t say for sure it’s caused by the different version, but it does seem likely given it seems to compile for him.

Do you guys have any idea if this could be the issue? Any help is greatly appreciated.

Could be the addition of the is bullet change on collision objects?

Yes, this is a very likely cause of the problem. By opening the project in a new version and saving it the bullet property has been added to the collision objects, and since you are using an older version which doesn’t know of this property you get an error. Revert using version control or manually edit the file(s) in a text editor.
