Cpop Helper

A set of a few tools which I thought might be useful in maps I'm planning to make. Currently all the additions are subpixel-themed, but despite helper's name, I will probably just use it as a general purpose helper for what I devise.

Currently includes:

• Set Subpixel Trigger: sets player's subpixel values to some prescribed value. Can be set to either do it on every frame, or only when the player is stationary. Can work independently for horizontal and vertical subpixel.

• Check Subpixel Trigger: complementary to the above, checks whether the player's subpixel value (horizontal and/or vertical) is equal to a prescribed value, or lands within a prescribed range. The currently supported actions are: kill the player on incorrect subpixel value (think of it as adding a spinner gap of sub-pixel width); set the flag on correct subpixel value; set the flag on correct subpixel value.

• Cpop Block: an entity you can put on top of a solid tile, which makes cpops no longer subpixel dependent. Has three customizable leniency variables: how long you have to wait before regrabbing the wall (which for vanilla cpops is variable 1-3, depending on vertical subpixel), how many frames of window you have to regrab, and how many frames of window you have to jump after regrabbing (both windows are 1 frame in vanilla). You can also choose which side of the block to apply it on, in case you have a 1 tile wide wall.

• Quiz Controller: displays a number of either text- or image-based options, of which only one is "correct". The player then has to pick the correct one by entering a suitable Quiz Answer Trigger, resulting in killing the player, setting a flag, or spraying some confetti! For TASing purposes, the randomization essentially depends on death count only. To aid replayability, this can be changed by enabling the quizVeryRandom flag (this makes randomness also depend on TimeActive on room load).

• HD Graphic (potentially unstable feature!): Displays an arbitrary high-resolution image of your choice in-game! It uses the SubHUD render layer, which means it will render in front of almost all other entities. Works with most PNG files. Warning: due to rendering jank, some images may not render on some versions of the game, and could potentially even cause a crash. Please test your map thoroughly if you use this entity!

• Theo Jelly: Behaves like a jelly, but inherits some properties of a Theo crystal - it kills the player if the jelly is destroyed, and prevents the player from transitioning out of the screen unless held (both of these properties being toggleable).

This helper is my first "real" programming project, so I would appreciate any feedback whatsoever, including of course bug reports. My terrible source code is available here.

I'm also open to feature requests, but can't guarantee I will fulfill them.

TODO:

• Support for quizes with multiple groups of answers, randomizing which one correct (displaying a randomized question at the controller).

• Write explanation for how to use the quizzes.
