Question about FXModuleLookAtConstraint

[Angelo Kerman]

I've seen this module in a few parts like the grappling device and some wheels, but I don't understand how it works. Could someone shed some light on this?

Here is an example

MODULE

{

name = FXModuleLookAtConstraint

CONSTRAINLOOKFX

{

rotatorsName = Piston1

targetName = Sleeve1

}

}

How would I set up the mesh to work with the module?

Thanks for your help.

This module basically causes an object in the exported part to point at another object in the same part along its blue transform axis. I use it for pistons and similar things.

Each ConstrainLookFX defines one relationship. The rotatorName defines the object that will be rotated to point at the targetName (again, along the blue transform axis in Unity). Usually for a freely moving piston, two relationships are needed, one to cause the piston to point into the sleeve, and one to cause the sleeve to point into the piston:

MODULE

{

name = FXModuleLookAtConstraint

CONSTRAINLOOKFX

{

rotatorsName = Piston1

targetName = Sleeve1

}

CONSTRAINLOOKFX

{

rotatorsName = Sleeve1

targetName = Piston1

}

}

For good setup, you want to confirm 3 things

1) That the rotator object's blue transform axis is correctly specified for the pointing you want

2) That the pivot of the rotator object is located at the point where you want the rotation to occur

3) That the pivot of the target object is located where you want the rotator object to point.

Then, it's just a matter of exporting and ensuring the names are correct in the module
