Dunno
Good luck!
Frameworks aren't an issue, I put them into the Frameworks
folder in my hand made bundle and they load fine.
When running the executable, it loads the image when it's in
the same folder but when running the executable through the
bundle, it doesn't find the image anywhere.
are you loading using relative or absolute addresses (
../../Resources/img.png or $BUNDLE_ROOT/Resources/img.png ) ?
also check the cwd when launched from the executable vs, the
bundle. Also does Console give any output?
I fixed it by using:
string path = thisExePath();
int index = to!int(path.lastIndexOf(/));
if (!GameFont.loadFromFile(path[0 .. index]~/vertiup2.ttf)) {
writeln(Font failed to load);
}
Now my hand made bundle works fine and loads resources from
inside the bundle.

How to make Application bundle from Executable? (Mac)
I managed to copy an application bundle and change stuff inside it to run my executable, but it was very manual and kinda hackish. Also I can't get my application to load images that I place in the Resources folder(or any folder in the bundle for that matter). Is there an official way to turn a D executable into a Mac Application Bundle?

I was debating switching to SDL but now I'm only debating between switching from SFML to DGame. When I leave my SFML game running for 7 hours, it uses 700mb of ram. Also my friend can't play my games due to missing dylibs(the SFML setup process is complicated). Those are the main reasons I'm looking for an alternative. I'll do a DGame test, if it beats SFML on those issues- I'm hooked.

Though if one message length is off by even 1 byte, then all future messages get corrupted?
Trying to make a TCP server, client connects and disconnects immediately
I managed to get the client to connect but immediately on the

Concurrent Thread Safe List?

Most tiny classes probably should be structs. More generally,
use a struct every time you don't need a class.
You can start with those two:
struct SBRange {
double left = 0.0, right = 0.0, top = 0.0, bottom = 0.0;
}
struct Point(T) {
T x, y;
}
This probably isn't enough to solve your problems, but it's a

I did a test and ran GC.collect() every loop but my memory

Would you know why this is using hundreds of mb of rams?
Try with only drawStart stripped.
If it still does it, then its redraw. Also try with just a hard
coded call to drawStart.
Something smells wrong here.
Without drawStar, my program starts at 24mb and slowly increases.
With drawStar my program starts at 70mb and increases at twice
the rate.

If it is a class, or otherwise contains pointers, then this is probably the source of your problem. class CircleShape : Shape is defined in dsfml.graphics.circleshape, so there's no going around this... - Building your program for x86_64 - 64 bits of address space will make fake pointer pinning very unlikely The binary included in the zip was 64-bit, so fake pointers shouldn't be that much of a problem. Oh, and I take back what I said about suspecting that SpaceBackground.stack grows infinitely. It probably doesn't. I don't have DSFML installed, and therefore couldn't recreate the behaviour. Is there a way to set a variable to be cleared in the new GC collection or to forcibly release a variable? I have an inkling that it might be the Sprite class or something with the RenderTextures.

I feel like the only way I can get better right now is if someone with more knowledge can give me some advice on the code I have written. Here's the link: http://cl.ly/0s0Q1L1S3v0E How can I make it use less CPU/RAM? (Most code is in the Misc/SpaceBackground.d)

The answers to your question can be found here: http://dlang.org/d-array-article.html In short, D arrays are actually not arrays directly, but slices of arrays (i.e., pointer and length pairs to a segment of memory managed by the GC). Therefore, assigning the return value of .remove back to tiles is extremely efficient, because all you're doing is updating the .ptr and .length fields of tiles. There is no copying of array elements at all (except what's already being done in .remove). However, the problem comes when you call .remove immediately followed by ~=. Because the runtime doesn't know whether you have made other slices of the same array in the meantime, it doesn't know whether you wish to retain the original array elements, so to be safe, whenever the array length shrinks it assumes that the next time you append something new, it should reallocate. Thus, every time ~= follows .remove, the array will be reallocated, which is extremely slow. The solution is to tell the runtime that yes, you do wish to overwrite whatever may have been there in GC memory before when you append: tiles = tiles.remove(i); assumeSafeAppend(tiles); // --- this is the secret tiles ~= tile; // now this won't reallocate everytime Note that append to the array will still reallocate occasionally (e.g., when there is no more space in the currently allocated GC block, and the array needs to be moved to a new memory location where a bigger block can be allocated). But it should perform a lot better than reallocating every single time you append. T Thanks! My project use to hover at 80mb ram usage, now it hovers at 35mb ram usage. Nevermind. It just climbed up to 65mb Okay now I'm very confused. When I have my program fully hidden behind another window, my ram usage goes up without going down. Which my program is partly visible it goes up a few mb then returns to the past amount of mb. Is this a bug?

The problem is with having three constructs with the same name:
package, module, and class.
I would use lowercase for package, and module names, and
differentiate between the package and the module:
.../source/foogame/game.d
module foogame.game;
class Game

Question about Allocating
I've been working on my game and am getting some pretty gnarly memory problems. I think it's how I'm allocating. Sometimes when I use variables I can do Color(255, 255, 255). But why is that different than new Color(255, 255, 255)? Same when I'm making arrays. new int[](0) vs []. What's the difference?
