That's something i'll soon be facing myself. It may be a long shot but i would try to create a temporary shape in the editor with proper collision settings, then save its prefab and load it back when attaching it to your character.

Thanks guys, camera:move worked as suggested!

I'm setting my camera based on my model's position/rotation but i'd like the camera to be positioned a little further back so i can actually see the model move, i think what i'm looking for is something like vector forward. Right now, i'm setting it at the exact same x/z coordinates. Vec3 pos = player_entity->model->GetPosition(); camera->SetPosition(Vec3(pos.x, pos.y + 2, pos.z)); What would be required to re-calculate the new x/z coordinates of the camera?

I like to use onedrive for large attachments. If you have a hotmail or live account, you should automatically have access to it. https://onedrive.live.com/

I haven't thought of doing it that way, i'll give that a try. I've also been trying to search for the .tex file format specification, i need to know its size but i'm not getting any good results from search engines, do you have any documentation about it?

I have lots of gui graphics and i would like to combine them into a single file that won't be packaged in the zip file, would it be possible to instruct the texture loader to load from file offset and length? Something like: Texture* Load(const std::string& path, int flags=0, const uint64 fileid=0, uint64 file_offset, uint64 file_length)

I'm not sure why it's not loading it, seems to be the same behaviour as if sandbox were enabled and if the .dll would be missing, you'd probably get a different error message. I zipped a new werk project that is working, the dlls are in it, i tested it on 2 computers. https://onedrive.live.com/redir?resid=1653f4923c37f970!280&authkey=!AJZ_t62yU-UXsJA&ithint=file%2czip

One of the dll is probably 64bit, someone else had this problem, i repackaged the binaries, it should work and make sure you disable lua sandbox. https://onedrive.live.com/redir?resid=1653f4923c37f970!276&authkey=!AOU-Ikv6sEBjcCY&ithint=file%2czip

I'm using a buffer to draw a minimap along with a dot representing my position. The dot is a normal texture that i'm loading, 1x1 white image and when i draw it on the buffer, i want to set its color like in context->SetColor but it stays white. Is there some way to obtain the context of a buffer? Buffer* buf = Buffer::Create(minimap_width, minimap_height); buf->Enable(); buf->Clear(); buf->SetColor(1, 1, 0, 1); // does not set color like context->SetColor does //minimap->Draw(0, 0); //buf->SetColorTexture(minimap); dot->Draw(pos.x, pos.y, 5, 5); // resizing my dot 5x5 buf->SetColorTexture(dot); buf->Disable(); m_rendertarget = buf->GetColorTexture(); // dump the buffer into a texture buf->Release();

I solved the alpha issue using this: m_texture_elements[0]->texture->Draw(0, 0, m_texture_elements[0]->texture->width, m_texture_elements[0]->texture->height); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); m_texture_elements[0]->texture->Draw(50, 0, m_texture_elements[0]->texture->width, m_texture_elements[0]->texture->height); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); m_texture_elements[0]->texture->Draw(80, 0, m_texture_elements[0]->texture->width, m_texture_elements[0]->texture->height); Every time i draw sequentially on the same buffer, i have to enable GL_BLEND and set blend flags, is it normal?

It's an uncompressed RGBA texture 128x32, MipMaps:8. I'm trying to create a render target (buffer) and draw on it. Then i later found i could just texture->draw on a created buffer. The only problem i'm facing now is that if i try to draw another image with alpha over the first one, it draws it opaque. I did try glEnable(GL_BLEND) but it didn't work. m_buffer->Enable(); m_buffer->SetColor(m_background_color); m_buffer->Clear(); m_buffer->SetColor(1, 1, 1, 1); // first one draws fine m_texture_elements[0]->texture->Draw(0, 0, m_texture_elements[0]->texture->width, m_texture_elements[0]->texture->height); // not applying alpha over first one m_texture_elements[0]->texture->Draw(60, 0, m_texture_elements[0]->texture->width, m_texture_elements[0]->texture->height);

I took this example from the documentation for SetPixel, i commented out Texture::Create and replaced it with Texture::Load but it crashes when doing memcpys but it doesn't if i don't load a texture and use Create instead. The texture loads fine, i'm able to display it. Error: HEAP[Test.debug.exe]: Heap block at 0655D900 modified at 0656192C past requested size of 4024 Test.debug.exe has triggered a breakpoint.

The dll file was compiled on 64-bit os, i've recompiled a 32-bit version, you can download it here https://onedrive.live.com/redir?resid=1653f4923c37f970!281&authkey=!ALGpG7kylnkqhW4&ithint=file%2czip The 32-bit dll files are now part of the original package listed in the first post.

Here's a new lib that i just finished that will allow game controller support for Lua fans! EDIT: Source: https://onedrive.live.com/redir?resid=1653f4923c37f970!278&authkey=!ABW8a3PdvzR_8cE&ithint=file%2czip Binaries (dll & so): https://onedrive.live.com/redir?resid=1653f4923c37f970!284&authkey=!AM0p2lTBH1mMSzk&ithint=file%2czip A lua example is provided, you can simply overwrite your existing App.lua with mine on a new test project. * Note: Lua sandbox must be disabled to use libs. Unfortunately i don't have linux installed so i couldn't compile it for that platform and I was able to compile it under Linux but i didn't get the chance to test it as i don't have the sdl2 binary libs. I included the full source should anyone want to re-compile it. Those that don't want to, simply copy LuaGamePad.dll file where your game executable is. You'll need to copy SDL2.DLL there as well, it's included. Tested with: - Logitech Rumblepad - Xbox 360 controller (XInput) Cheers!

If you only have the indie version it won't work but i think there's the possibility to make a dll accessible to lua like luasqldbi but i don't know how to do that yet. I'll let you know if i'm successful.

Here's the game controller class i just finished. Copy the SDL folder in your source directory (currently SDL2-2.0.3). Include SDL2.lib in your project and copy SDL2.DLL in the same folder as your executable. Edit: Added 2 parameters in the init method to enable/disable auto reacquire.

I've been writing a c++ class using SDL in the last few days and it's almost finished. There were issues with my xbox controller, keys aren't mapped the same as regular controllers but i managed to fix it and implement a button mapping feature and now it behaves like normal controllers. It can automatically re-acquire controllers that are unplugged/replugged. I will post the code once i'ts done, after that, i'll add lua support.

Check the Projects/Windows folder, there's a solution file you can use with VS.

This may be what you're looking for, it's an example of lua table retrieval to c++: http://lua-users.org/lists/lua-l/2004-04/msg00201.html EDIT: Sorry i just realized that script variables aren't accessible in c++, i haven't found anything that would do it, perhaps it must be done from the engine.

Done and it worked, many thanks Josh!

In the perspective view, i could move in my scene and rotate the camera by holding the right mouse button but it doesn't work anymore, i see the mouse cursor disappear when trying to rotate but no rotation. I couldn't find any options that would affect this, should i re-install?

Damn that was meant for an Entity class, which was part of my Map_Entity class previously but removed because accessing members or methods within the script caused a crash and forgot to get rid of that delete. Thanks again for pointing out my silly mistake!

In App.h Map_Entity* map_characters[100]; In App.cpp (App::Start) entities[0] = Model::Load("Models/Characters/Dwarf/dwarfmale_run.mdl"); map_characters[0] = helpers->InitModel(entities[0], ENTITY_TYPE::PC, "Rygar", Vec3(0, 0, -5.73), 0.02, 1, COLLISION_TRIGGER, Entity::CharacterPhysics, "dwarfmale_run_bone_64", "dwarfmale_run_bone_LFingerRing"); IScript* script = new PlayerScript(entities[0], map_characters[0], window); In Helpers.h #ifndef _HELPERS_H #define _HELPERS_H using namespace Leadwerks; class Map_Entity; enum ENTITY_TYPE : uint8 { NPC = 0, PC = 1 }; class Helpers { public: Helpers() {} Map_Entity* InitModel(Entity* entity, ENTITY_TYPE entity_type, std::string name, Vec3 position, float scale, float mass, const int collision_type, const int physics_mode, std::string boneWeapon, std::string boneShield); }; #endif In Helpers.cpp #include "../entities/entity.h" #include "helpers.h" using namespace Leadwerks; Map_Entity* Helpers::InitModel(Entity* entity, ENTITY_TYPE entity_type, std::string name, Vec3 position, float scale, float mass, const int collision_type, const int physics_mode, std::stringboneWeapon, std::string boneShield) { Map_Entity* new_entity = new Map_Entity(); if (new_entity != NULL) { delete new_entity; } if (entity != NULL) { entity->SetScale(scale); entity->SetMass(mass); entity->SetPosition(position); entity->SetGravityMode(true); entity->SetCollisionType(collision_type); entity->SetPhysicsMode(physics_mode); entity->Hide(); new_entity->boneWeapon = boneWeapon; new_entity->boneShield = boneShield; new_entity->aniSpeed = 35; new_entity->entity_type = entity_type; new_entity->name = name; new_entity->set_mass_delay = 0; new_entity->anim_length[0] = entity->GetAnimationLength("Run"); new_entity->anim_starttime = 0; for (int aa = 0; aa < sizeof(new_entity->anim_speeds) / sizeof(*new_entity->anim_speeds); aa++) { new_entity->anim_speeds[aa] = 30; } new_entity->speed = 5; return new_entity; } return NULL; };

I'm passing several objects in my IScript initializer: class PlayerScript : public IScript { public: PlayerScript(Entity* e, Map_Entity* me, Window* w) :IScript() { m_entity = e; map_entity = me; m_window = w; } void Collision(Entity* entity, float* position, float* normal, float speed) { } Map_Entity is a simple class with variables that i'm passing to the script when initialized: class Map_Entity { public: float speed; std::string boneWeapon; std::string boneShield; uint8 anim_speeds[5]; }; Problem is, the Map_Entity data passed to the script doesn't retain their values after exiting the constructor method. I could copy every values manually or do a memcpy but i'd rather not if i don't have to. I've been reading for hours and looking at a lot of examples and still can't figure it out.

Here's how both classes look like now: class IScript { protected: Entity* ent; public: IScript() {} virtual void Collision(Entity* entity, float* position, float* normal, float speed) = 0; virtual void UpdateWorld() = 0; virtual void UpdatePhysics() = 0; virtual void SetEntity(Entity* entity) = 0; }; class PlayerScript : public IScript { public: PlayerScript() :IScript() {} void Collision(Entity* entity, float* position, float* normal, float speed) { } void UpdateWorld() { } void UpdatePhysics() { } void SetEntity(Entity* entity) { ent = entity; } }; I've changed my constructor for PlayerScript(Entity* e) :IScript() { ent = e; } and removed SetEntity method and now using IScript* script = new PlayerScript(entities[0]); like you suggested. Thanks!
