The Behaviour Messages

These are the behaviour messages.

activePose:

This will take any animation currently set as the incoming transforms of the agent and drive the character to the pose defined therein. To constantly drive an agent to an animation, this message must be sent every frame. The stiffness of the characters joints will determine how closely they match the animation pose.

The mask value determines which effector sets will be modified. Specifying 'fb' or no mask value will cause the effect to be applied to the whole character.

Otherwise, specify 'l' or 'u' for the first character to mask off to just lower or upper body parts. Then, you can specify the following for the second character:

When the first character is 'u', the second parameter can be:
* 'c' = just clavicles
* 'l' = left arm only
* 'r' = right arm only
* 'a' = both arms and clavicles
* 's' = just spine
* 't' = torso only, eg. spine & arms and Clavicles
* 'k' = trunk only, eg. spine & head
* 'n' = neck and head
* 'b' = everything
* 'w' = wrists

when the first character is 'l', the second parameter can be:
* 'l' = just left leg
* 'r' = just right leg
* 'b' = both legs

note that the characters should be lower-case.

grab:

NOTE: An upper body behaviour.

An upper body behaviour that Grabs or Braces against a point, the nearest point on a line or the nearest point on a surface. Turns head, twists body and pelvis. Set useleft and useright to use the desired hands. Grab will create a constrant between the hand and a object. Brace will not create any constraint.

This behaviour can be played over other behaviours. However it includes logic about if and when to grab, so will not grab things behind the character or things that are out of reach.

There are 3 ways to specify the grab points.

Points: right grab/brace point (pos1) and/or left grab/brace point(pos2).

Line: grabs/braces with the left and/or right hand to the nearest point on the line between (pos1) and (pos2).

Quad Surface: grabs/braces to the surface specified by (pos1), (pos2), (pos3) and (pos4). These points must be specified in a anitclockwise order.

The normals ( right/left are normal(normalR)/normal(normalL) respectively) can be specified for all of the grab point input methods. If no normal is specified the behaviour will attempt to find the appropriate normal.

The grab points are specified in the coord frame of the instance specified by instanceIndex. ( -1 = world space).

rollDownStairs:

Curls into foetal position, at a speed defined by the strength and damping values; This behaviour is full-body and resets the character when it starts.

zAxisSpinReduction float 0.00 Tries to reduce the spin around the z axis. Scale 0 - 1

Feedback Type Behaviours Used Description
Start sub behaviour Roll Up

shot:

Behaviour when shot by a gun. General affect is to reach for the body part and stagger... weakening only when given a shot_relax message.
You can be shot after hitting the ground and the character will react.
Arms that are not holding or injured will flail to maintain balance.
The character weakens briefly on each shot so as to emphasise the effect of each shot.

Head will look at wound or headLookPos alternatively for a random amount of time between headLookAtHeadPosMinTimer and headLookAtHeadPosMaxTimer. Initially will look at wound for headLookWoundMaxTimer amount fo time.

Parameter Type Default Range Units Description

addShockSpin boolean false if enabled, add a short 'shock' of torque to the character's spine to exaggerate bullet impact

randomizeShockSpinDirection boolean false for use with close-range shotgun blasts, or similar; choose a random direction to apply shock-spin, rather than derive direction from bullet velocity/impact

alwaysAddShockSpin boolean false if true, apply the shock spin no matter which body component was hit. otherwise only apply if the spine or clavicles get hit

shockSpinMin float 50.00 minimum amount of torque to add if using shock-spin feature

shockSpinMax float 90.00 maxiumum amount of torque to add if using shock-spin feature

shockSpinLiftForceMult float 0.00 if > 0, apply a force to lift the character up while the torque is applied, trying to produce a dramatic spun/twist shotgun-to-the-chest effect. this is a scale of the torque applied, so 8.0 or so would give a reasonable amount of lift

shockSpinDecayMult float 4.00 multiplier used when decaying torque spin over time; 4.0 = decay in ~1/4th of a second. 1.0 = decay over ~1 second.

shockSpinScalePerComponent float 0.50 torque applied is scaled by this amount across the spine components - spine2 recieving the full amount, then 3 and 1 and finally 0. each time, this value is used to scale it down. 0.5 means half the torque each time.

Feedback Type Behaviours Used Description
