UCC 3.3.5 Issues

[Cheo]

Hello, here's the usual bug report video for the latest update :

-Since at least one version ago, it is possible to hear the landing sfx when falling near a surface but not on it. This is reproducible in the double jump section of the demo scene.

-The player can't move on surfaces using the Frictionless physics material. Is this normal ?

-The demo UI for the boss stomp has two overlapping texts.

-The Ride section - do I even need to say it again ?

-The FPS arm objects can clip through walls by default. I tried looking for the URP setup steps for that, but the documentation page seems to have been removed.

Thanks for the report. I've marked this thread for the next update.

I'll add to this thread - when building a new character and setting "Unity IK" to true, the CharacterBuilder doesn't add the CharacterIK component. Was this intentional?

Source Code:

public static void AddUnityIK(GameObject character)
        {
            var animatorMonitors = character.GetComponentsInChildren<AnimatorMonitor>();
            for (int i = 0; i < animatorMonitors.Length; ++i) {
                var animator = animatorMonitors[i].GetComponent<Animator>();
                if (animator == null || !animator.isHuman || animator.GetBoneTransform(HumanBodyBones.Head) == null) {
                    continue;
                }
            }
        }

Changes Made:

public static void AddUnityIK(GameObject character)
        {
            var animatorMonitors = character.GetComponentsInChildren<AnimatorMonitor>();
            for (int i = 0; i < animatorMonitors.Length; ++i) {
                var animator = animatorMonitors[i].GetComponent<Animator>();
                if (animator == null || !animator.isHuman || animator.GetBoneTransform(HumanBodyBones.Head) == null) {
                    continue;
                }
                animator.gameObject.AddComponent<CharacterIK>();
            }
        }

The issue with the landing sfx is still reproducible in UCC 3.3.8.

You can fix this in 3.3.8 by changing line 117 within Fall.cs from:

                    SurfaceManager.SpawnEffect(m_CharacterLocomotion.GroundedRaycastHit, m_LandSurfaceImpact, m_CharacterLocomotion.GravityDirection, m_CharacterLocomotion.TimeScale, m_GameObject, m_Transform.forward, false);

to:

                    // The ground cast can graze a nearby ledge. Confirm that the surface is beneath the resolved landing position.
                    // Include the collider radius so slopes can be detected when the character's pivot is above the surface.
                    var castOffset = m_CharacterLocomotion.Radius + m_CharacterLocomotion.SkinWidth;
                    var ray = new Ray(m_CharacterLocomotion.TargetPosition + m_CharacterLocomotion.Up * castOffset, -m_CharacterLocomotion.Up);
                    var groundCollider = m_CharacterLocomotion.GroundedRaycastHit.collider;
                    if (groundCollider != null && groundCollider.Raycast(ray, out var hit, castOffset * 2)) {
                        SurfaceManager.SpawnEffect(hit, m_LandSurfaceImpact, m_CharacterLocomotion.GravityDirection, m_CharacterLocomotion.TimeScale, m_GameObject, m_Transform.forward, false);
                    }

I can still reproduce it reliably in the double jump section of the demo scene :

 

[Justin]

Thanks, it looks like the footstep code needs to change:

Within CharacterFootEffects.FootStep, change:

Mathf.Abs(m_CharacterLocomotion.LocalVelocity.y / TimeUtility.DeltaTime)

// To
Mathf.Abs(m_CharacterLocomotion.LocalVelocity.y * TimeUtility.DeltaTime)

The issue with the sfx played when not landing is now fixed, however this introduced a new issue : when standing magically in the air by being close enough to the ground and having Slide disabled, the land sfx does not play when jumping. From a realistic point of view this kinda makes sense, but if from the controller's point of view a collider is still preventing the character from falling that collider's surface should still be used to produce an SFX. In addition as you can see at around 0:07 in the attached recording the sfx did not play when jumping onto the lower pillar's surface.
