Batched raycasting wrapper in C

I have a friend maintaining UPBGE - (a fork of blender game engine running in blender 2.9x)

I was wondering what the name of the batched raycast system was under the hood so we can wrap it / more information about it for upbge

note- we are building using bullet 2.83

Re: Compound Physics Armatures

https://www.youtube.com/watch?v=ydnqXhktudk here is a update -turned physics vizulisations on in this one
*force applications are done with raycasts at the moment - the child shapes moving produce no thrust* as they 'teleport' each frame

Compound Physics Armatures

So I have found an easy way to get an accurate physics shape for actors in blender I have a compound root object - the armature to be animated parents to this, each bone that is to have physics has a 'bone tag' parented to it, and a child shape that approximates the shape of the bone every frame I r...

Re: change cap of friction per material in blender game?

the sim is set for 100 material in both the feet, and the ground plane,

however during the 'power stroke' I still end up with slipping.

I will check my base walk animation then get back to you *(maybe he is lifting his feet to the end of the walk stroke?)

change cap of friction per material in blender game?

currently material friction is capped at 100 in blender game engine


I need more :P

Re: Explosion simulation for use in rendering (blender and B

Thanks! I used rays and vetor.reflect(surfaceNormal) and at each bounce I cut the force in half :D

collision.hitImpulse all objects in collision.hitObjectList

Can someone help add a system to blender game engine, so that each collided impulse is saved from all actors (per physics frame?) like for impact in collision.hitObjectImpulses: if impact.magnitude>2: actor.health-=impact.magnitude right now it's impossible to do damage using physics directly, and i...

Blender game needs triangle mesh to many convex hull convert

how can I

1. Generate many convex hulls from a triangle mesh using blender BPY. for later use in game engine,

2. build a compound object out of these shapes before frame 0? (bge api)

Re: Influence of Kinematic Object

I would use torque or linV

Diff = object.worldOrientation-target.worldOrientation

own.worldAngularVelocity = Diff*multiplier

own.worldAngularVelocity*=.5
