300 to 800 what? Bytes? Kilobytes? Megabytes? It could just be the memory needed by your map. Game assets are quite large in size.

Success! Did some digging around in my test code. Apparently sizeof(char*) doesn't return the size of the static array, but just the size of a charater. Thanks G++. http://martyj.net/curl.zip I can't find libcurl-dev on windows for the life of me, so I had to use Linux. As I am working off of a server, I don't have Leadwerks setup so I cannot implement it in your class. Sorry about the indentation as well. I was using nano to modify the files. But this should help hopefully.

For the life of me I cannot reproduce the hmac hash. Using the key from the python file and the JSON from my sample, I get the following: import hmac import hashlib key = "16813a12f718bc5c620f56944e1abc3ea13ccbac" data = "{\"platform\":\"Windows\", \"os_version\":\"10\", \"sdk_version\":\"api v2\"}"; hash = hmac.new(key, data, digestmod=hashlib.sha256) hash.hexdigest() Produces the following HEX string a39a45d2ac53e7c4d9e3b978267a6442cad0c396a52500e6c3be9e5bb1e6edbb Using the library I posted earlier I get a completely different result. Using the following code which uses OpenSSL's version #include <string.h> #include <stdio.h> #include <openssl/hmac.h> #include <openssl/evp.h> void hmac(unsigned char* key, unsigned char* message, int keylen, int messagelen, unsigned char* out) { HMAC_CTX ctx; HMAC_CTX_init(&ctx); unsigned int len = 32; unsigned char* data[32]; // Using sha1 hash engine here. // You may use other hash engines. e.g EVP_md5(), EVP_sha224, EVP_sha512, etc HMAC_Init_ex(&ctx, key, 20, EVP_sha256(), NULL); HMAC_Update(&ctx, message, messagelen); HMAC_Final(&ctx, out, &len); HMAC_CTX_cleanup(&ctx); memcpy(out, data, len); memset(out+len, 0, 32-len); for(int i = 0; i < len; i++) { printf("%02x", out[i]); } printf("\n"); } int main(int argc, const char *const *argv) { unsigned char buff[32]; const char* message = "{\"platform\":\"Windows\", \"os_version\":\"10\", \"sdk_version\":\"api v2\"}"; const char* key = "16813a12f718bc5c620f56944e1abc3ea13ccbac"; hmac((unsigned char*)key, (unsigned char*)message, sizeof(key), sizeof(message), buff); } I get the following printed. 0000000000000000b076bf49007f0000d859c149007f00008707400000000000 This sample code seems to work well. The problem is it is only windows. http://stackoverflow.com/questions/22147895/is-it-possible-to-do-a-hmac-with-wincrypt

They are combined with this hash https://github.com/unixpickle/LibOrange/blob/master/LibOrange/hmac-sha256.c Then base 64 encoding the result of that. I can give you a better example Saturday morning.

I think their python example gives the best use case of how their auth works. http://restapidocs.gameanalytics.com/#python-example # sandbox game keys game_key = "5c6bcb5402204249437fb5a7a80a4959" secret_key = "16813a12f718bc5c620f56944e1abc3ea13ccbac" # sandbox API urls url_init = 'http://sandbox-api.gameanalytics.com/v2/' + game_key + '/init' init_payload = { 'platform': platform, 'os_version': os_version, 'sdk_version': sdk_version } init_payload_json = json.dumps(init_payload) headers = { 'Authorization': hmac_hash_with_secret(init_payload_json, secret_key), 'Content-Type': 'application/json' } try: init_response = requests.post(url_init, data=init_payload_json, headers=headers) except: print "Init request failed!" sys.exit() Notice the line 'Authorization': hmac_hash_with_secret(event_list_json, secret_key), Makes use of this function def hmac_hash_with_secret(message, key): return base64.b64encode(hmac.new(key, message, digestmod=hashlib.sha256).digest()) Create hmac hash based upon key and message. Base64 encode hmac hash.

While you're in there adding http requests with libcurl, you should make them available for other C++ developers without using libcurl . It would be nice to do a request to a URL with a map as GET or POST params.

Here's a video of me testing out multiplayer syncing. If anyone is interested in helping me test multiplayer, it would be lovely to not have to run two clients by myself!

Two Questions 1. Are you using the sandbox API keys for the sandbox API? 2. Are you creating the Authorization header correctly? From what I can tell, it's a hmac hash of your POST data using your secret key, then base64 encoding it I looked into CURL a little bit further. Here is my text example thanks to libcurl's example. /*************************************************************************** * _ _ ____ _ * Project ___| | | | _ \| | * / __| | | | |_) | | * | (__| |_| | _ <| |___ * \___|\___/|_| \_\_____| * * Copyright (C) 1998 - 2015, Daniel Stenberg, <daniel@haxx.se>, et al. * * This software is licensed as described in the file COPYING, which * you should have received as part of this distribution.

What you're setting the body to isn't valid json. What I would do is see if you can use CURLOPT_POSTFIELDS and pass it like this: curl.setOptString(CURLOPT_CURLOPT_POSTFIELDS, "platform=Windows&os_version=10&sdk_version=rest api v2"); What library of CURL are you using? I can try to get a quick example tomorrow morning of each of the different requests.

I would love this as well.

So it looks like you have to init the API first. POST /v2/<game_key>/init Your body data needs the following fields: platform, os_version, sdk_version The Docs ask for JSON to be submitted, but I'd imagine URLEncoding should work. Once you do that, you should be able to create different events here: POST /v2/<game_key>/events Depending on the category in your data, your fields change. For example, a Category of business appears to support the following fields: category, event_id, amount, currency, transaction_num, cart_type, receipt_info A Category even of type Resource requires the following fields: category, event_id, amount.

I see. Does having an update hook effect performance much? I have an object that I add an update hook on when it gets interacted with, then I hide the object. After x number of seconds, I show the object, and would like to remove the hook as it's no longer needed to check to see if it should show. What would be the best way to do this?

In the non-beta branch. When removing a hook on an entity in the Hook's callback, an access violation occurs. When removing a hook on an entity NOT in the hook, everything works as expected. Code: void tempHook(Entity* entity) { if (Window::GetCurrent()->KeyHit(Key::J)) { entity->RemoveHook(Entity::UpdateWorldHook, tempHook); } } bool App::Start() { temp = Model::Box(3, 3, 3); temp->AddHook(Entity::UpdateWorldHook, tempHook); return true; }

Are you using apache? You could use mod_rewrite. Something like <IfModule mod_rewrite.c> RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^workspace/(.*)$ community/$1 [R=301,L] </IfModule> I'm not 100% sure the exact syntax as I am not an apache expert. Check out this link for more info http://httpd.apache.org/docs/current/mod/mod_rewrite.html

Oh man that would be great for the editor. I'm having to add a bunch of pivots to do a similar functionality, and it is terrible as far as keeping track of things.

Is Josh considering buying a tiny house? Or RV living?

SVN? I mean it works well if it's just one dev. Pain in the *** to do branching.

Any update to this? I know you're super busy with the new UI.

See PM with link and instructions on how to reproduce.

It would be nice if Leadwerks had the ability to resize the map without having to export, then resize, then re-import.

My computer took a **** on me at the moment, I can get you GIT access right now, or in a week I can get you a zip of the project.

If you look at the stacktrace on the image, there is no way that I could use it after I release it as the exception is thrown in library code that is above my Release call in the stack. So it's somewhere in Leadwerks code that the crash happens, in the RemoveAll function.

On my demo map, the game crashes whenever I drop an item. (And only on this map). I am on the Non-Beta branch. Here is the crash I receive: http://imgur.com/a/oVIJL Sample Code: Creation this->model = (Model*)Model::Load(item->GetModelPath(), Asset::Unmanaged); this->model->SetUserData(this); this->model->SetKeyValue("name", item->GetName()); this->model->SetVelocity(Vec3(0, 0, 0), true); this->model->SetCollisionType(Collision::Prop); this->model->SetPhysicsMode(Entity::RigidBodyPhysics); this->model->SetPickMode(Entity::SpherePick, true); this->model->SetMass(10); // TODO: real mass this->model->SetSweptCollisionMode(true); this->model->SetPosition(position, true); Destroy Code ItemEntity::~ItemEntity() { this->model->SetParent(NULL); this->model->Hide(); // TODO: Delete me this->model->SetUserData(NULL); this->model->Release(); } I can provide my full source code if needed.

Here is the crash I receive: Creation: this->model = (Model*)Model::Load(item->GetModelPath(), Asset::Unmanaged); this->model->SetUserData(this); this->model->SetKeyValue("name", item->GetName()); this->model->SetVelocity(Vec3(0, 0, 0), true); this->model->SetCollisionType(Collision::Prop); this->model->SetPhysicsMode(Entity::RigidBodyPhysics); this->model->SetPickMode(Entity::SpherePick, true); this->model->SetMass(10); // TODO: real mass this->model->SetSweptCollisionMode(true); this->model->SetPosition(position, true); Destroy Code: ItemEntity::~ItemEntity() { this->model->SetParent(NULL); this->model->Hide(); // TODO: Delete me this->model->SetUserData(NULL); this->model->Release(); } I should mention, this doesn't happen on every map. Just the map of my demo.
