  • Can I set position of path constraint?

【Question】
Can I set position of path constraint by code?

If so, How can I do?

【current status】

  1. spine file
    It has one path which has one bone, and this bone's path constraint's position is 35%.

  2. code for get path constraint's position

    console.log("path constraint's position : " + this.skel?._skeleton.pathConstraints[0].position);

And it is success.

Yes, you can. You just get a reference to the path constraint and change the position. If your position is using the percent mode, you'd set it to eg 0.45 for 45%. Note if you have an animation that keys the path constraint position, you'd probably want to change it via code after applying the animation.

this.skel?._skeleton.pathConstraints[0].position = 0.45;

Thank you, Nate.

One more question.
I try the code like this :

this.skel?.setAnimation(0, "animation1", true);
console.log("path constraint's position : " + this.skel?._skeleton.pathConstraints[0].position);
this.skel?._skeleton.pathConstraints[0].position = 0.45;
console.log("path constraint's position after set position : " + this.skel?._skeleton.pathConstraints[0].position);

And have error like this.

In this case,
what is my missing point?

It solved!

I just change the code from

this.skel?._skeleton.pathConstraints[0].position = 0.45;

to

this.skel!._skeleton.pathConstraints[0].position = 0.45;

Cool, glad you figured it out!
