Pain Day II

[garrynewman]

So pain day. All your shit is broke. Here's what's changed

SceneWorld, SceneObject moved to world

• When creating a sceneobject you need to define a world to create it in. Use Map.Scene to define the game world.
• Some classes were renamed for consistency, all start with "Scene" now.

PhysicsWorld exists

• Previously PhysicsWorld was a static that let you access the game's physics world
• Now you can create your own PhysicsWorld (if you see the need)
• Creating a PhysicsBody requres you pass in the world in which to create it (use Map.Physics to access the map's scene world)
• PhysicsWorld.Gravity is now available at Map.Physics.Gravity

Entity.Camera doesn't exist

• Camera is now CameraMode
• CameraMode is an Entity component
• You can get an entity's camera with Components.Get<CameraMode>()
• You should be able to replace most of your camera calls with Player.CameraMode

Entity.ActiveChild doesn't exist

• It's up to you to define this
• Unless you're using the Player class, in which case it's there

Animgraph Changes

• PawnAnimator.SetParam is now SetAnimParameter
• AnimEntity.SetAnimFloat etc is now SetAnimParameter
• Will complain if parameter is missing
• Will complain if parameter is wrong type
• Will try to convert int to float, and float to int, since that's a common mistake

Render Changes

• ModelEntity.Liquid (and LiquidManager) was removed (should be an addon thing, not applying to every model)
• Render.BlendMode was removed (UI has it as a shader variable now)
• Render.ZBufferMode, CullMode etc removed
• Render,Set( .., .. ) is now Render.Attributes.Set
• Render.Compute is now ComputeShader

Other Stuff

• EntityManager was deleted
• Map.Reset added
• Carry functions were moved from Entity to BaseCarriable
• RevoluteJoint is HingeJoint
• WeldJoint is FixedJoint
• PhysicsBody.Entity is now PhysicsBody.GetEntity()
• PhysicsGroup.GetBodyIndex( body ) is now body.GroupIndex
• Render.Set is now Render.Attributes.Set
• SceneObject.SetValue is now SceneObject.Attributes.Set

Getting this spammed for my pawn animator now.

[garrynewman]

What is velocity in your animgraph?

[DoctorGurke]

Yeah seems to be a type mismatch, why didn't it error like this before? Not sure why this always worked fine, passing a vec3 to float

[garrynewman]

it failed silently before, now you're gonna find out if you're messing up

[DoctorGurke]

gotcha, thanks

[DoctorGurke]

getting a null assert sometimes seemingly randomly

before the assert it errors this a bunch

[garrynewman]

This is good stuff, thanks

Great update!

Some questions regarding PhysicsJoints:

1. Is there any possibility to get the start and end position of a PhysicsJoint like it was available previously? (e.g. via Vector3.DistanceBetween(spring.Body1.Position, spring.Anchor2))
2. ReferenceMass was removed from springs. How is it working now, how can I define the "elasticity" / strength of a spring?
3. "Strength" property of a PhysicsJoints describes as "If it takes any more energy than this, it'll break", but my spring doesn't break no matter what small number I'm using. Is this intended? (PhysicsJoint.CreateSpring(from, to, 0f, 10f).Strength = 0.2f;)

[Alf21]

Oh, and it seems that we can't change the Camera(Mode) anymore on serverside, so we must use clientside. Is this intended (regarding possibly intended serverside camera restrictions?) If so, are there any recomendations or should we e.g. use an RPC to trigger a camera change on spawn?

Thanks, I'll work through these today
