Destoying from scene shows all children deleted, but still childrens are visible in scene on collision : - On collision with the saw, this is happening : - onLoad() { this.animationComponent = this.node.getComponent(Animation); this.animationComponent.clips[0].name What’s happening wrong with the collision detection code?

Components: The data attached to entities, like meshes, physics, or animations. Want collision? One Last Piece: The Collision System With almost every system in place, I’m now working on the Collision System—the last big piece of this rewrite. Want to add physics? setEntityKinetics(). setEntityCollision(). What’s Next?

Analysis The whole effect can be split into two parts, one for the simulation of the mesh and one for the rendering of the mesh. No need to define the vertex format, and even Cocos has support for sprite meshes. Well, it’s very comfortable, much more comfortable than just a mesh, and it has some practicality too.

Object Placement on Terrain (Mesh)

Mnenad

JANUARY 25, 2018

This chapter is all about how I solved it (so far) to be able to place all kinds of assets like 3D-meshes or self-growing fractal seeds on the terrain. Let’s assume we do it for each vertex on a mesh with let’s say 10’000 vertices. Asset placement - depending on mesh height vertices. Before we start.

Godot 3.2 adds support for convex decomposition

Mircosoft Game Dev

APRIL 9, 2019

This makes the workflow for 3D games considerably easier, by allowing conversion of concave meshes of any form into a set of convex shapes. Triangle mesh shapes ( ConcavePolygonShape ) work very well as static colliders, but they are useless for rigid bodies or areas, as they have no internal volume. The convex problem.

And on startup, the collider doesn’t change position, but the renderer mesh and character controller move and hit this collider. And added a new element to the collision matrix, which was used to separate the player. I added a collider to the node where the character controller is. I solved my problem like this.

Soft Body in Godot 3.1

AUGUST 6, 2018

To create a Soft Ball is to add a SoftBody node and add a mesh to it, in this case I used a sphere maded in Blender (I used a custom mesh because the sphere created dynamically by Godot is not completely closed, but just for a test you can use it). Now open the PlaneMesh properties and set the size( x: 0.5
