Saw this was a common thing asked for, so here's a simple way of doing double taps in C# and GDScript.
GDScript
func _process(delta):
if (dash_cool_down_u > 0):
dash_cool_down_u = dash_cool_down_u - 1 * delta
else:
dash_button_count_u = 0
func _input(event):
if (event.is_action_pressed("ui_up")):
if (dash_cool_down_u > 0 && dash_button_count_u == 1):
print("double tapped Up")
else:
dash_cool_down_u = 0.5
dash_button_count_u = dash_button_count_u + 1
C#
using Godot;
using System;
public override void _Process(float delta)
{
if (dash_cool_down_d > 0)
{
dash_cool_down_d = dash_cool_down_d - 1 * delta
}
else
{
dash_button_count_d = 0
}
}
public override void _Input(event)
{
if (event.is_action_pressed("ui_down"))
{
if (dash_cool_down_d > 0 && dash_button_count_d == 1)
{
print("double tapped down")
}
}
else
{
dash_cool_down_d = 0.5
dash_button_count_d = dash_button_count_d + 1
}
}
