b-cancel / Unity3D_character_To_KeyCode.cs
Last active June 17, 2023 15:37
UNITY 3D => Unity Key Codes to Characters (for MOST keys that display a character when pressed)
//NOTE: This is only a DICTIONARY with MOST character to keycode bindings... it is NOT a working cs file
//ITS USEFUL: when you are reading in your control scheme from a file
//NOTE: some characters SHOULD map to multiple keycodes (but this is impossible)
//since this is a dictionary, only 1 character is bound to 1 keycode
//EX: * from the keyboard will be read the same as * from the keypad... because they produce the same character in a text file
Dictionary<char, KeyCode> chartoKeycode = new Dictionary<char, KeyCode>()

FLUTTER => Using Widget Sizes to calculate the Sizes of other widgets Automatically Or Manually
import 'package:flutter/material.dart';
import 'dart:async';
//Desired Behavior on FIRST build (It should not take 3)
//CASE 1 (parent uses child size) : eye.width = vane.width * 10
//CASE 2 (child uses parent size) : pupil.width = iris.width / 2
//CASE 3: (child uses sibling size) : iris.width = vane.width * 5
//Desired Sizes (can be read from Render Tree in Flutter Inspector) [in original config of 4 letters]
//vane = 30

OUTPUT (one of many) NOTE: how far behind the Loose Timer is, is not predictable either

FLUTTER => Ensures that "TextFormFields" are visible when focused in Flutter
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter/rendering.dart';
import 'package:flutter/services.dart';
import 'package:meta/meta.dart';
/// Note:
/// [*] some functions are async simply because that schedules them after something else that should happen first for everything to work properly
/// [*] you really should not use "ensureVisible" or "ensureErrorVisible" or "KeyboardListener" unless that field is already wrapped in "EnsureVisibleWhenFocused"
/// you will get very unusual behavior
