An image creation tool? What about Robo's World 3? Where did this come from!?
In an attempt to create a lightning special effect for my game, I ended up creating about 6 different special effects. Each time I made a change to the coding of the system I tried it and thought, "Oh hey! This looks pretty cool, I should save it!" And so I did. Once I had all the effects, I thought it would be a shame to let all this effort go to waste, so I re-purposed the experiment into this image creation tool, and due to the nature of the tools, I decided to call it Line FX.
While this isn't really a game, it is the shortest amount of time that I have spent on any project I have made in Game Maker ever,... thanks to winter holidays I was able to create the entire program in less than a week!
So have fun, go nuts and create something amazing!
If you want to check out the tools available for this program, check out this feature.
If enough people ask, I will make the source code for this available. Just ask nicely in either a comment on this article or send me a message.
Finally, if anyone sends me an image they created with Line FX and I find it to be of good quality, I will feature the creation in the "images" for this tool.
