Or that the YoYo Compiler target evaluates expressions and functions backwards?! This article is chock full of information about those facts and more. It's up to you to deal with wrong or missing input, according to your needs.This article has been updated since its original posting on June 20, 2018.ĭid you know you can prompt a user to send a pre-written Tweet from YoYo Games’ GameMaker in just a single line of code? How about this: numbers are less-precise on the HTML5 target when compared to the Windows target. There's so much to do to improve this code, but it works fine as a starting point. This function takes a 1-char string and returns its value in the decimal system, it does the same for letters A-F and loops back (thanks to mod) for other letters (which is a nicer alternative to throwing an exception, in my opinion, despite harder debugging). The support function hex_to_dec() is used to convert individual HEX values into their decimal counterparts by checking against their ASCII values: // Converts a HEX value in a decimal number This function takes a string in the format #000000 (including the hash character) and converts it to RGB values stored in a ds_map, and accepts both uppercase and lowercase letters. Hex_to_dec(string_char_at(hex_code, 6)) ) Hex_to_dec(string_char_at(hex_code, 4)) ) ġ6 * hex_to_dec(string_char_at(hex_code, 5)) + Hex_to_dec(string_char_at(hex_code, 2)) ) ġ6 * hex_to_dec(string_char_at(hex_code, 3)) + ![]() Var hex_code = string_upper(string_lettersdigits(argument0)) ġ6 * hex_to_dec(string_char_at(hex_code, 1)) + Then I came up with quite a simple implementation: // Converts a HEX colour value in an RGB map 208 + 10 = 218.Īnd so on for all the remaining values.
