Hi community,
on base of an android-sourcecode (URL below) i made a godot-c#-clock for learning c#:
heres the code:
using Godot;
using System;
public class Clock : Node2D
{
private int height, width = 0;
private float radius = 0.0f;
private int offset=10;
private int handTruncation, hourHandTruncation = 0;
private int[] numbers = {1,2,3,4,5,6,7,8,9,10,11,12};
public override void _Ready()
{
height=200;
width=200;
int min = Math.Min(height, width);
radius=min/2;
handTruncation = min / 20;
hourHandTruncation = min / 7;
}
public override void _Process(float delta)
{
Update();
}
public override void _Draw()
{
DrawClockCircles();
DrawHands();
DrawNumerals();
}
public void DrawClockCircles()
{
var center = new Vector2(width / 2 + offset, height / 2 + offset);
var color = new Color(0, 0, 1, 0.5f);
DrawCircle(center, radius, color);
DrawCircle(center, 12, color);
}
public void DrawHand(double loc, bool isHour, Color color, float w) {
double angle = Math.PI * loc / 30 - Math.PI / 2;
int handRadius = isHour ? (int)(radius - handTruncation - hourHandTruncation) : (int)(radius - handTruncation);
var from = new Vector2(width / 2 + offset, height / 2 + offset);
var to = new Vector2( (float) (width / 2 + Math.Cos(angle) * handRadius + offset), (float) (height / 2 + Math.Sin(angle) * handRadius + offset));
DrawLine(from, to, color, w, true);
}
public void DrawHands()
{
DateTime now = DateTime.Now;
float hour = now.Hour;
hour = hour > 12 ? hour - 12 : hour;
var color = new Color(1, 1, 1);
DrawHand((hour + now.Minute / 60) * 5f, true, color, 3.0f);
DrawHand(now.Minute, false, color, 3.0f);
color = new Color(1, 1, 0);
DrawHand(now.Second, false, color, 1.0f);
}
private void DrawNumerals() {
for (int number = 1; number < numbers.Length+1; number++) {
String tmp = number.ToString();
double angle = Math.PI / 6 * (number - 3);
int x = (int) (width / 2 + Math.Cos(angle) * radius - tmp.Length / 2);
int y = (int) (height / 2 + Math.Sin(angle) * radius + tmp.Length / 2);
var center = new Vector2(x + offset-5, y + offset+5);
var color = new Color(1, 1, 1);
var label = new Label();
var font = label.GetFont("");
DrawString(font, center, tmp, color);
}
}
}
how to start: start a new project 2d, add a Node2D, to the node add a c#-script with the code above, change screensize in preferences to 220x220, backgroundcolor to black and transparency to 0.5
