This article has been updated since its original posting on June 20, 2018.

Did you know you lot tin prompt a user to send a pre-written Tweet from YoYo Games' GameMaker in merely a single line of code? How about this: numbers are less-precise on the HTML5 target when compared to the Windows target. Or that the YoYo Compiler target evaluates expressions and functions backwards?! This article is brimming total of information almost those facts and more.

Welcome to a curated list of twenty "Quick Bits", GameMaker Studio ii tips, tricks, and code snippets that come from my Step Event Twitter account. Whether you're seasoned with the software or just getting started on your game making journeying, chances are yous'll learn something new.

#19 - GameMaker number precision can be unlike depending on targets

Epitome Transcript

Numbers are actually treated every bit floating point values when doing comparisons in GMS. You may become different results on different platforms when checking what apepars to be an integer.

HTML5 target has less precision than Windows target. 0.5 + 0.5 does non equal 1 with floating point maths, and it may be that 1 is really something similar 1.000000000001.

To go around this, you tin can apply the floor() or round() functions to generate a fixed integer value.

#xx - GameMaker expressions and functions are evaluated differently using the YoYo Compiler

  • Formatting your numbers, like currency, is as easy every bit casting integers to a string and adding a comma character every tertiary space, starting from the end.

• What tin I do to finish my game from lagging?

  • Every bit #half dozen demonstrated, you can use the delta timing functionality to assist combat lag in your game.
