Hi all,
Construct is really a great freeware tool we can use to code a game, but itself alone can't handle all the job. We need graphics, sounds, etc.
I'm starting this thread because i think many people here doesn't have too much $$$ to spend on tools for such task (photoshop came in mind), and besides, not everybody has knowledge to do artwork or anything else. But there are many free / open source or cheap alternatives and free resources that can do the job very well, and to help everybody, a good compiled list in on thread should help a lot, huh?
For this thread (that also could be called as 'how to make games if you are short on money'), i will contribute with some tools i've found on internet that are free;
* TOOLS - GRAPHICS *
FREEWARES OR OPEN SOURCE
Gimp - http://www.gimp.org/
A well known image editor, this one isn't a full photoshop replacement, but probably it's the most complete free one. You can deal with layers, multiple undos, many features and export work in many bitmap formats. Plus, it accepts 3rd party extensions! Supports tablet pen pressure.
Mypaint - http://mypaint.intilinux.com/
This one could be called the free Corel Painter tool. It's very simplistic and minimalistic in terms of features and interface, but it shines when it comes to the brush engine. Also supports tablet pen pressure.
Inkscape - http://inkscape.org/
The best freeware vector-drawing alternative i know (if not the only one). Good drawing tools (bezier, free form), good plugins, bitmap export.
Hornil Stylepix - http://hornil.com/en/products/stylepix/
A decent and very small image editor, although not as good as Gimp. Has layer support, effects, and more. Also supports tablet pen pressure.
RealWorld Paint.COM - http://www.rw-designer.com/image-editor
Weaker than Hornil, but yet with useful features like layer support. Again, this one supports tablet pen pressure. Interface very clumsy.
* TOOLS - ANIMATION *
FREEWARES OR OPEN SOURCE
Synfig studio - http://synfig.org/
A very complete open source animation software, that supports automatic inbetween animation (like flash). Doesn't have bones system.
Plastic Animation Paper - http://plasticanimationpaper.dk/
This one was released some time ago as a full freeware animation app. It's designed for traditional (frame by frame) animation.
Cool Motion - http://www.yuzhesoft.com/cool-motion.html
This one is a free alternative to flash 6/7 ( mx / mx2004, if i do remember correctly), although less powerful, but still very useful. It can only import bitmap files to the library, but has a vector drawing tool, has some transforms and motion tween, so it has enough resources that makes it suitable to cut-out animation like flash. Supports AS aswell. If you are familiar to flash, you will be familiar with this one, since interface is very similar to its comercial counterpart. Has some bugs (freezes here everytime i try to dropdown comboboexes), but perfectly usable. Unfortunately doesn't support bones like newer flash version, and only exports swf output. But, there are some freeware tools floating around that converts SWF to image sequence or png spritesheet. Take a look at SWFSheet (good one - http://www.bit-101.com/blog/?p=2977 ) or Kurst SWF Renderer (simpler but efficient - http://swfrenderer.kurst.co.uk/) or SwfSpriteSheet (not tested - http://fermmm.wordpress.com/2011/02/04/swf-spritesheet-creator/) - they all relies on adobe air framework, wich is also free.
TISFAT - http://t.sektorz.net/
This little one is very buggy when it comes to frame by frame exporting, but it's also free and has pivotal animation system that behaves much like 2d skeletal animation system (bones). Features timelines, layers and keyframes, similar to Flash. Neat features that could really be useful (i've heard rint screen? lol)
* TOOLS - MUSIC*
FREEWARES OR OPEN SOURCE
Pxtone - http://hp.vector.co.jp/authors/VA022293/pxtone/index.html
A simple music composing software, it's good for 8-bit styled retro music. The same tool was redistributed with a great manual by Locomalito (from hydorah fame) and is available at: http://www.gr87.com/?page_id=64
LMMS - http://lmms.sourceforge.net/
Excerpt from LMMS site: "LMMS is a free cross-platform alternative to commercial programs like FL Studio?, which allow you to produce music with your computer. This includes the creation of melodies and beats, the synthesis and mixing of sounds, and arranging of samples. You can have fun with your MIDI-keyboard and much more; all in a user-friendly and modern interface."
