Daunted by interests
07 Aug 2014, 12:53 am
I am daunted by the chores before me from my 3 interests:
Creating a complete SMB2J Disassembly (go to http://sm2.beneficii.net/ for more info), which I've been working on a lot, but it is repetitive. Thankfully, the SMB Disassembly by Doppelganger is very helpful in this disassembly.
Re-creating the SMB3 Map Editor with wxWidgets and make the code much easier to maintain and for someone to edit if they need to. Unfortunately, much of my knowledge has been lost and I have to reread my old code to figure it out.
Creating something that can allow me flexibility in drawing birds-eye view of roads, with all the changes in size (like addition/removal of a lane), with intersections, on and offramps, curving, etc., while maintaining a cross-section.
I am daunted by the amount of work it takes to engage in these activities.

I keep talking to myself negatively, like in my father's voice, about how purposeless these all are. Just hack Super Mario World and have fun with that! Lunar Magic works like perfectly with it.
The road task though now looms large in my mind.

EDIT: Made crucial adjustment.
My brain gets foggy and tired as I work late into the night on my road project. Here, I read SVG paths, with some limitations (z not supported, multiple m's not supported, and arcs not supported):
bool not_started_flag = true, last_cubic = false, last_quad = false;
for (std::size_t i = 0; i < path.Length; ++i) {
switch (static_cast<char>(path[i])) {

case 'C':

case 'a':
case 'A':
path.insert(i + 1, " ");
}
}
wxStringTokenizer tkn(path, ", \t\r\n", wxTOKEN_STRTOK);

This has cost me a lot of spoons and I'm nervous again.

Still looking at it and picking at it. This is how I get dehydrated.

My code is so error-laden, I don't even know if I can get it to work.
