Orx vs PlayMaker + Unity3D

Powerful config system that makes orx data-driven and provides an easy to use load/save system.

Good friendly development community ready to help each other with tips and advice for setting up and best practices.

Automatic hot-loading of resources upon modification on disk, shortens drastically iteration times.

Written in C with high emphasis on memory and CPU efficiency.

Supports Windows, Linux, Mac OS X, iOS and Android.

Orx is a Data Driven engine that greatly reduces required code. You can configure object definitions, bodies, cameras, sound, animation, event tracks, etc.

GLSL code can be added straight into data configuration files and can be applied to any texture: background or objects whivh allows for some amazing effects. All GLSL versions are supported, again by providing the shader language version in your configuration file.
Parameters are supported and values over time for shader animation.

Clock system that provides time consistency and allows time stretching + high precision timers

Color and translation FX are simple to configure and apply to objects.

Includes a chaining graph & custom animation events for synchronization.

Uses the zlib license. Lets you use Orx for free for any kind of projects, even for commercial ones.

All input devices are fully supported: Joysticks, Mouse, Gamepad, Keyboard and Touchscreen. Multiple physical devices and be mapped the same binding.

Rated the fastest engine in the OpenFL’s BunnyMark since October 2015.

Samples for sound effects, or streams for music. All sounds can be groups via audio buses just like in a typical DAW (Digital Audio Workstation).
All sounds can be spatial relative to the camera.

Camera/viewport scheme allowing multiple views displayed with camera translation, zoom and rotation.

Fragment (pixel) shader support, render to texture, MRT, easy composition and custom rendering support.

Integrated runtime profiler (with graphical display) to easily spot which parts of your game need to be optimized.

Supports .bmp, .png, .jpg, .tga and .dds

Orx provides a excellent c++ wrapper for object oriented design, called: orx/Scroll. You can, of course, roll your own.

You'll need to put more time in learning Unity + Playmaker compared to something like GameSalad. But once get the hang of it and familiarize yourself with what it's possible to build with them, it's quite easy to use.

For those developers who can't afford an artist, or aren't skilled enough to create their own art, Unity features an Asset Store full of a wide variety of free and paid assets that can be easily added to your game. The Asset Store has more than just music and art. It also has code and modules that can be added to your game such as unique lighting or GUI systems.

A lot of third party plugins have support for Playmaker. Playmaker team also invest time to add support for a lot of third party plugins.

Instead of a single "if this then that" event list which can become very cluttered beyond the most basic behaviors, PlayMaker gives each object a list of states where only certain events are triggered, and performing an action also changes state.

This allows for a clean, simple visual representation which helps break complex logical structures into smaller pieces, making them easier to understand.

It basically can do same things as scripting in Unity.
