Mr sun canvas example
I want a canvas example that will be a simple god game, or a kind of game where things move forward on there own, and there is just a little interaction from the player now and then. I have come to like to play, and make these kinds of games these days. Playing a game can end up eating up a lot of time, so I like games that just move along on there own, and I can just step in and make a few changes now and then. Games like sim city, and roller coaster tycoon come to mind when it comes to this.
Anyway the canvas example that I had in mind here is a game where there is this world where there is a sun at the center of a circle, and the rest of the world is along the circumference of this circle. By default the sun starts at the center of this circle world, but the player can move it to any location within this world. The circumference of the outer circle of this world is divided into sections, and each section object has a percentage value, and this percentage value is effected by the distance of the section to the sun object.
There is a lot that comes to mind when it comes to moving forward with this kind of project. but one must start somewhere right? So with that said lets take a look at what I have so far with this one.
1 - The utils module for Mr Sun
To start off this canvas example I will want to start a general utility module for it. As a canvas example grows I want a module where I can place methods that I might end up using in more than one location when it comes to having a bunch of modules that will make up the whole of the code.
For this canvas example I have my get canvas relative method that I want to help with getting a canvas relative position when it comes to working with pointer events. In addition I also have the distance formula, which is yet another usual suspect when it comes to these kinds of custom cut utility modules that I make for these examples.
2 - The game module for Mr Sun
So now for the game modules that will be used to create and update a game state module. For this canvas example there is the sun object, and then a collection of sections objects that are the main display objects of interest here. The public API of this main game module has a method for creating a new game object, updating the sections of the game object, and moving the sun object.
The main idea here is to keep the code that has to do with creating and mutating a game state object away from everything else.
3 - The draw module for Mr Sun
This is very much a canvas example so of course I have a draw.js module for it like always. I take a moment to break things down into a while much of draw methods, one for each little aspect of the view for this. I have a draw method just for the background, one to draw the sun, and another to draw the sections of the sun thus far.
4 - Main.js
5 - Conclusion
When I have this canvas example up and running I have the very basic idea of what I had in mind working at least. So far so good, but now the next step is where to go from here. There are many ideas that I have in mind when it comes to moving forward with this example when it comes to turning it into an actual game of one kind or another. I am thinking that I will want to have some code that serve as a more complex world generator, that will set different types for the various sections in the world. That is having a section that is a land type, ocean, swamp, mountain, ect. There would also be a process where life will spring up if conditions are right for it. Of course it goes without saying that moving the sun around will change the situation for that.
So then the idea here is to have a world that can be left alone, or at any moment I can come along and move the sun around destroying everything, or make it so that one side is way to hot, and the other side is ice cold. There are all kinds of things that this can effect when it comes to adding more plug-ins, and improving the source code for the core of the application here.
When it comes to forks, and additional plug-ins so far I have a Mr Sun Temp canvas example. In this canvas example I forked the source code that I have here, and made a few minor improvements to it. In addition I made a few more plu-ins that are a step in a direction to start to make something that can be thought of as an actual done deal of some kind. This focus on this example is to creating a nice base collection of plug-ins that have to do with setting temperature for the sun as well as thw world sections. In addition I also made some more plug-ins that have to do with fusion, and therefor the creating of minerals, and another plug-in that has to do with some more advanced features of the sun object.
In addition I also have started a Mr Sun Geo example where I am forking the source code of Mr Sun Temp to take yet even another step forward with this. In this fork I created yet even more plug-ins that have to do with additional features of the Mr Sun game World that have to do with the GeoSphere of the World. That is things like Geology, a Hydrosphere, and Atmosphere. Which all Strokes me as the next step in this kind of project.
