adding collision object to impact pathing

extollo

i want to be able to dynamically add a object and have it impact GeneratePath (ie Pathing.GetPathPoints).

so i add a physics object similar to a clog

<!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1-->losMovementBody = Shared.CreatePhysicsSphereBody(true, radius, 0, coords)
losMovementBody:SetGroup(PhysicsGroup.BigStructuresGroup)
losMovementBody:SetPhysicsType(CollisionObject.Static)
losMovementBody:SetEntity(entity)<!--c2--></div><!--ec2-->

GeneratePath is pathing through the object.

what do?

Check out ObstacleMixin.

changed to ..
<!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1-->Pathing.AddObstacle(origin+ Vector(0, -100, 0), radius, 1000)<!--c2--></div><!--ec2-->

Still no work. i'm doing the arcane xlat -Y direction & use a large height that is in AddToMesh

curious ...

why does Pathing.GetPathPoints have the Y translation it does on generated path points?

I had a path that went from 0 to .8 in the Y dir, but the start & intermediate points had a 1.2 Y. the last two points in the path changed to the correct Y at the destination.

Short Answer - So drifters and macs can fly over obstacles.

All buildings that have obstacle mixin do exactly what you want, they create a dynamic path but, as some AI 'fly' they need to be able to pass over the obstacle where possible.

I am fairly sure you don't need to amend the pathing settings, just add ObstacleMixin.lua to the load files of the object you are trying to add...

ie - <!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1-->// ======= Copyright (c) 2003-2011, Unknown Worlds Entertainment, Inc. All rights reserved. =======

yea, i figured it was for drifters - was just wondering how that was parameterized, so i could change it during generation instead of post processing the path.

trying the mixin approach next. i was hoping to avoid creating a full entity & just temporarily plop in an obstacle via code as I show in my snippet.

If you want to just temp drop an obstacle, why not use something that is already in the game? If you create an instance of the object, then all it's data will be there, and you can then remove it when necessary?

It's the simplest way to do it as far as I can see, without knowing the full extent of your plans of course. hahaha

no. i needed a custom object. i've decided to go in a different direction, but the whole exercise was interesting - knowledge was gained.

Bring this up, Pathing.GetPoints ignores obstacles (totally?), like armory.
Any that it will not ignore them?

. Pathing is fine with inbuilt. I had trouble dynamically creating a custom object that would impact the pathing algorithm. Went in another direction and never went back to see if I could get it to work. May look at this stuff again - i must have accidentally clicked awesome when browsing on my phone. lol that's ok, you're awesome jim.
