Description

PRAction is a GameMaker Studio 2 (GMS) module created by Prismatic Realms, Inc. It is an action/animation system that is similar to a tweening system, but is so much more than that. At its very basic level, PRAction allows you to modify an object's properties from one value to another over time, but it takes this concept several steps further. The idea is that you create "action" objects, each of which represent a specific object property changing from one value to another over a given amount of time. Then you can package any number of these actions together into complex groups and sequences that, when played by a object, will be executed like an action script from a movie. Actions, and groups of actions, can be played in a loop and repeated any number of times. Furthermore, actions are reusable. So when you create an action, you can keep it around to use over and over on any number of your game objects.

Any of your object's properties can be animated in this way. PRAction gives you many functions that allow you to animate their x/y positions, alpha value, rotation angle, scaling factors and much more. You can also animate your object's colour properties to transition from one colour to another smoothly. On top of that, you can also animate any of your own custom variables that you've added to your objects.

It doesn't end there. Properties can be animated "absolutely", meaning that you specify the "to" value that the property will animate to from it's current value. But you can also animate properties "relatively" so that rather than animating those properties TO any given value, you animate they BY a given value instead. PRAction includes a bunch of animation curve functions, also known as easing functions, that will animate those properties using a variety of different smoothing effects.

And if that isn't enough, there's more! Actions don't only have to involve modifying properties over time. There is an action that allows you to insert a "wait" command into your "movie script" to add pauses in between your actions. Actions can also be one-shot instant triggers! Such as running a script function, object method or user event, or playing a sound effect, destroying an object, running a room, changing an object's draw layer, or even instructing another object's actions to start playing at key points in your action sequence.

As a bonus, this extension includes several common and useful compound actions, ready to use in your project. These include floating, shaking, blinking, flashing, flipping, wobbling and more. Use them as is, or as examples to create your own compound actions.

PRAction will save you tons of time when coding your animations. There is nothing to it: First, you define the actions and then you instruct an object to play those actions. That's it! There is no messing about with alarms, or tracking frame counts or anything else. Just play it, and then forget it.

The sky's the limit with this extension. Animate anything to your heart's desire.

This package contains a parent object that implements PRAction that your objects can derive from as well as several script assets that contain the functions you use to create actions and animate your object properties. The package also contains documentation on how to use the module and example code that you can learn from.

Friendly support is just an email away and you can expect a quick turn-around to answer your questions and resolve issues. As always, comments and suggestions are welcome!

Versions

GMS2 - Version 1.3.0. Published May 9, 2019

-Added PRActionDestroyObject function. Creates an action that will destroy the current object. -Added PRActionGotoRoom function. Creates an action that runs the given room. -Minor changes to JDOC descriptions.

GMS2.3 - Version 2.0.0. Published January 27, 2021

NEW FEATURES * Because the action creation functions now accepts function names for the easing parameters rather than constants, you can now more easily provide your own custom easing functions as parameter values, if desired. * Added an additional argument for the PRActionCreateQPopIn and PRActionCreateQPopOut functions for added control over the easing functions used for their effect.

IMPROVEMENTS * Implemented updated in-house module format and naming conventions. Please read the note PRAction_Information for details. * Revamped the entire module to take advantage of the new GML features of GameMaker Studio 2 v2.3. * No longer uses an extension to implement PRAction. Now uses a parent PRAction object and scripts. * It is no longer necessary to place PRActionInit(), PRActionUpdate() and PRActionDestroy() in your objects to turn your objects into PRAction object. Now, simply make the oPRAction object the parent of your object. * Makes full use of structures instead of arrays to track action properties.

BUG FIXES * Fixed colour clamping bug for colour-related actions. * Fixed bug that caused PRAction to crash if the object running actions was destroyed.

NOTES * All of the Core functions and Additional functions have been moved into the oPRAction object as instance methods. They are no longer functions defined in the global scope. As such, they have also been renamed. For example, function PRActionPlay has now been renamed to PRPlayAction. Please see documentation for full list of instance method names. Note that this will require some refactoring of your code if upgrading from a previous version of PRAction. * All of the script functions that create actions have been renamed. For example, function PRActionMoveBy has been renamed to PRActionCreateMoveBy. Please see documentation for full list of function names. * All of the PRActionEaseId* constants have been eliminated. Functions now accept the names of the easing fun
