Hi community,
meshinstances added from c# script to test how to add for example spheres. in the first example with metallic material and random positions/colors - only for fun and to get a nice picture:
using Godot;
using System;
public class Spheres : Spatial
{
public override void _Ready()
{
for (int i = 0; i < 77; i++)
{
NewSphere();
}
}
public void NewSphere()
{
var r1 = new RandomNumberGenerator();
r1.Randomize();
MeshInstance mi = new MeshInstance();
mi.Mesh = new SphereMesh();
var ma = new SpatialMaterial();
var color = new Color(r1.Randf(), r1.Randf(), r1.Randf());
ma.AlbedoColor=color;
ma.Metallic=0.85f;
ma.Roughness=0.4f;
mi.MaterialOverride = ma;
var newscale = new Vector3(r1.Randf()+0.4f, r1.Randf()+0.4f, r1.Randf()+0.4f);
mi.Scale=newscale;
var newtrans = new Vector3(r1.Randf()*10-5, r1.Randf()*10-5, r1.Randf()*10-5);
mi.Translate(newtrans);
AddChild(mi);
}
}
in the second example we change the code only in the way that we arrange the spheres on the x and z coordinates and change the y/height and the color by a function and we have a functionplotter. there are many other possible functions like 7*(Sin(x/5)+Cos(z)) etc (the code of the colors is not good ok):
using Godot;
using System;
public class Functionplotter : Spatial
{
// Called when the node enters the scene tree for the first time.
public override void _Ready()
{
for (int x = 1; x < 32; x++)
{
for (int z = 1; z < 32; z++)
{
NewSphere((float)x, (float)z);
}
}
}
public void NewSphere(float x, float z)
{
MeshInstance mi = new MeshInstance();
mi.Mesh = new SphereMesh();
var ma = new SpatialMaterial();
float d1=12.0f;
float function=(float)Math.Exp(-Math.Cos(x/d1*x/d1+z/d1*z/d1));
var color = new Color(function/2.0f/(x/2), function/2.0f/(x/10+z/10), function/2.0f/(z/2));
ma.AlbedoColor=color;
mi.MaterialOverride = ma;
var newscale = new Vector3(0.5f, 0.5f, 0.5f);
mi.Scale=newscale;
var newtrans = new Vector3(x*1.5f, function*4.0f, z*1.5f);
mi.Translate(newtrans);
AddChild(mi);
}
}
To start add a project-3D with a Spatialnode, add the c#script with code above, add a camera and a light...
btw: why are always some codelines outside the codesection can you tell me please?
