Unity 3D – Set render pipeline and fix the pink shader material.

The Unity 2018.1 comes with two scriptable render pipelines known as SRP templates the HDRP and the lightweight render pipeline. The idea is to provide optimized real-time performance. In Unity 2019.3 the lightweight render pipeline was renamed to Universal render pipeline. All render pipelines can be install from the Package Manager. You can install it… Read More »

Unity 3D – The readyplayer.me Unity package.

The Unity package can be found on this page. You can load it into your project, see the next image: You can have an error like this: Multiple precompiled assemblies with the same name Newtonsoft.Json.dll included or the current platform. Only one assembly with the same name is allowed per platform. (C:/ReadyPlayerMe001/ReadyPlayerMe001/Library/PackageCache/com.unity.nuget.newtonsoft-json@2.0.0/Runtime/Newtonsoft.Json.dll).

Unity 3D – Microgame FPS fix for build.

The Unity platform for learning comes with the Microgame FPS asset in order to learn the Unity 3D game engine. I started to use this microgame on Fedora 33 Linux distro with the Unity editor version 2020.1.10f1 and the Unity game engine version need by this microgame. I got errors in the build process when… Read More »

Unity 3D – How to use it in Linux.

In this tutorial, I will show you how to get started using Unity 3D in the Linux operating system. I used the Fedora distro and it worked very well. The common problem with Unity 3D on Linux operating systems is related to project management. I met her when I made the settings for the learning… Read More »

Unity 3D – A simple joystick project .

This is the most simple way to have a joystick on your game. The project comes with three images one for the exit application and two images for the joystick. One image is for the background joystick on this I add another image for the joystick. The projects have two C# scripts: one for the… Read More »

Lua – Script for Roblox to use a hat.

This is a simple scrip used by me to use a hat object for my Roblox player. The script needs to be put on the root of the hat object. If the hat has a bad orientation, then change the script variable AttachmentRight with a good vector. Let’s see the script:

-- (catafest hat Script - Loaded.)

debounce = true

function onTouched(hit)
	if (hit.Parent:findFirstChild("Humanoid") ~= nil and debounce == true) then
		debounce = false
		h = Instance.new("Hat")
		p = Instance.new("Part")
		h.Name = "catafest_fedora"
		p.Parent = h
		p.Position = hit.Parent:findFirstChild("Head").Position
		p.Name = "Handle" 
		p.formFactor = 0
		p.Size = Vector3.new(1, 1.2, 1) 
		p.BottomSurface = 0 
		p.TopSurface = 0 
		p.Locked = true 
		script.Parent.Mesh:clone().Parent = p
		h.Parent = hit.Parent
		h.AttachmentForward = Vector3.new (-0, -0, -0)
		h.AttachmentPos = Vector3.new(0, -0.1, 0.05)
		h.AttachmentRight = Vector3.new (0, 0, 1)
		h.AttachmentUp = Vector3.new (0, 1, 0)
		wait(5)
		debounce = true
	end
end

script.Parent.Touched:connect(onTouched)

-- (catafest hat Script - Loaded.)

debounce = true

function onTouched(hit)

if (hit.Parent:findFirstChild("Humanoid") ~= nil and debounce == true) then

debounce = false

h = Instance.new("Hat")

p = Instance.new("Part")

h.Name = "catafest_fedora"

p.Parent = h

p.Position = hit.Parent:findFirstChild("Head").Position

p.Name = "Handle"

p.formFactor = 0

p.Size = Vector3.new(1, 1.2, 1)

p.BottomSurface = 0

p.TopSurface = 0

p.Locked = true

script.Parent.Mesh:clone().Parent = p

h.Parent = hit.Parent

h.AttachmentForward = Vector3.new (-0, -0, -0)

h.AttachmentPos = Vector3.new(0, -0.1, 0.05)

h.AttachmentRight = Vector3.new (0, 0, 1)

h.AttachmentUp = Vector3.new (0, 1, 0)

wait(5)

debounce = true

end

script.Parent.Touched:connect(onTouched)

Godot – moon shader.

This is a simple tutorial is about how to create a shader moon in time. Into your Godot project add a Sprite to Node2D. Add a New CanvasItemMaterial and then select Convert to ShaderMaterial to the Sprite. Open this shader and fill with this shader source code:

shader_type canvas_item;
render_mode blend_mix;

void fragment(){
	float time = TIME;
	vec2 uv = UV;
	//moon
	float t = fract(time*0.01);
	vec2 p = uv; 
	p.y += p.y*0.5 + (t - 1.8);
	p.x += (t-1.8)+p.x*0.5;
	vec3 basecol = vec3(199.0,190.0,100.0);
	basecol.r += smoothstep( 0.2, 10.1, t*0.1);
	basecol.g += smoothstep( 0.2, 10.1, t*0.1);
	basecol.b += smoothstep( 0.2, 10.1, t*0.1);
	vec3 suncol=basecol;
	vec2 m = vec2(-0.1,-0.1);
	suncol = suncol*smoothstep(0.1, 0.01 , length(p)) * smoothstep(1.5,0.1,uv.y);
	COLOR = vec4(suncol,0.1);
}

shader_type canvas_item;

render_mode blend_mix;

void fragment(){

float time = TIME;

vec2 uv = UV;

//moon

float t = fract(time*0.01);

vec2 p = uv;

p.y += p.y*0.5 + (t - 1.8);

p.x += (t-1.8)+p.x*0.5;

vec3 basecol = vec3(199.0,190.0,100.0);

basecol.r += smoothstep( 0.2, 10.1, t*0.1);

basecol.g += smoothstep( 0.2, 10.1, t*0.1);

basecol.b += smoothstep( 0.2, 10.1, t*0.1);

vec3 suncol=basecol;

vec2 m = vec2(-0.1,-0.1);

suncol = suncol*smoothstep(0.1, 0.01 , length(p)) * smoothstep(1.5,0.1,uv.y);

COLOR = vec4(suncol,0.1);

}
