I've got lighting. I am using Pointlights. I also have a Geforce 8800 GS with 320 MB of RAM.

What is the best way to create interior rooms for use in Leadwerks in order to have optimal frame rates and stability? The reason I ask is because I created an entire level as just one mesh and I am getting horrible frame rates (between 16 and 20 fps). When I just have a simple section, like a hallway or an office, the fps is fine (around 90). Is it a good idea just to break up an entire interior level into smaller sections or is there something else that can be done in order to get optimal frame rates?

I'm using plane meshes and textures with alpha channels if I remember correctly and I'm parenting all of the plane meshes to the camera.

I am trying to render an outdoor scene with terrain, a skybox and my simple HUD. I can render the HUD in the transparency world with the Terrain, but I cannot render the skybox, terrain and HUD together. I can also render the skybox and terrain just fine by themselves also. I am putting my HUD in the transparency world like this: fw.GetTransparency().SetWorld(); CreateAmmoHUD(); CreateHealthHUD(); fw.GetMain().SetWorld(); I am rendering the skybox like this: fw.GetRenderer().SetSkybox(LoadMaterial("abstract::FullskiesBlueClear0016_2_L.mat")); When that is commented out terrain and HUD render fine. When it is uncommented then I get a black screen with the HUD display but no skybox and no terrain, however everything renders fine for the first frame and after that I get a black screen with the HUD only. Does anyone have an idea on how I can fix this, or is this potentially a bug? All help will be greatly appreciated.

Alright I got it working, but I have to export them out as obj files. FBX just doesn't export properly. Is there any way to get water reflection and shadows to work with vegetation being positioned using the vegetation placement tool?

I reset the xform by going to the Utilities tab, selecting the Reset XForm button and resetting the selected object. It looks like the model is of the correct scale, but the object is has now been rotated 90 degrees on the x or z axis so that it is now parallel with the ground when I export it out of 3ds max and import it into the Leadwerks editor. In 3ds max, however, it has the correct orientation. Any ideas on how this could be happening and how I can correct it?

I don't know what you mean by restarting the engine. I restart Leadwerks Editor every time I make changes to the models.

When I try to scale my source vegetation models in 3ds max and then place then into a Leadwerks scene using the terrain vegetation placement tool the models remain the same size as they were before I changed there size. I am exporting the models out of 3ds max using the fbx format. The models are properly scaled when I just add them as models. Is this a problem other people have had? Any and all help will be greatly appreciated.

I finally got some time to work on this. I was able to get it to work using the references you gave VeTaL, thanks. I am getting this stupid unhandled exception when the render context is set to NULL before a call to wglMakeCurrent. I do not know why it happens because it will work without any problems sometimes. It only seems to crash after running another app that was using OpenGL before. I don't know why this is happening yet, but I think it's because the MFC app cannot acquire an available render context. That doesn't make much such because I check to see if the render context was created successfully. Anyway I will continue to try. Thanks for all the help and input.

OK you guys are right. I set it up to no longer animate after the last frame of the death sequence. I did try this before, but I think the parameters I was using for the death sequence were not correct which was creating the incorrect results.

Alright I got it working. I had to rework my animation management code. The code below will animate a sequence (in this case a death animation sequence) and at the end of the animation it will stay on the last frame of the animation. next_frame = (AppTime() - animationStartTime) / 30.0f; next_frame = fmod(next_frame, 575-540) + 540; if(next_frame > fCurrentFrame) fCurrentFrame = next_frame; else { bNextSequence = true; next_frame = (AppTime() - animationStartTime) / 30.0f; next_frame = fmod(next_frame, 1) + 575; fCurrentFrame = next_frame; } Animate(swat_officer, fCurrentFrame, 1, 0, 1); Hopefully this helps anyone else that needs help with this.

I cannot get the animation to play with no recursion. I'm thinking that there is something wrong with the Animate function. Update: I wrote a simple program to try and isolate the problem. I can get the animation to work when the recursion parameter is 1 but not when it is 0. Here is my code in its entirety: #include "engine.h" #include "Framewerk.h" leadwerks::Framewerk fw; TModel swat_officer; int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd ) { flt next_frame, animationStartTime; if(!Initialize()) return 0; RegisterAbstractPath("I:\\Leadwerks\\LEAnimationTest\\LEAnimationTest\\Data"); //Create a graphics context Graphics(800, 600); if( !fw.Create() ) { MessageBoxA(0,"Failed to initialize engine.",NULL,0); return 1; } fw.SetStats(0); fw.GetRenderer().SetSSAO( false ); fw.GetRenderer().SetBloom( false ); fw.GetRenderer().SetDistanceFog(false); fw.GetRenderer().SetGodRays(false); fw.GetRenderer().SetHDR(false); AmbientLight(Vec3(0.7f, 0.7f, 0.7f)); PositionEntity(fw.GetMain().GetCamera(), Vec3(0.0f, 0.0f, -250.0f)); swat_officer = LoadModel("abstract::swat_officer.gmf"); PositionEntity(swat_officer, Vec3(0.0f, -75.0f, 10.0f)); animationStartTime = AppTime(); while(!KeyHit()) { UpdateWorld(AppSpeed()); fw.Update(); fw.Render(); fw.GetMain().SetWorld(); next_frame = (AppTime() - animationStartTime) / 30.0f; next_frame = fmod(next_frame, 1 - 200) + 1; Animate(swat_officer, next_frame, 1, 0, 0); Flip(); } return 1; } I am using Leadwerks Engine 2.31.

How do I get the character rendered at that frame? I tried using no recursion during the entire death sequence but the animation doesn't play at all when I do that.

I am trying to animate a character after he dies using the last frame of a death sequence. I cannot get this to work at all. I have some simple code to do this but it looks like the character just sits there at the first frame of animation of the idle sequence. flt next_frame = 575.0f; next_frame = (AppTime() - animationStartTime) / frameSpeed; next_frame = fmod(next_frame, 575 - 578) + 575; Animate(m_Entity, next_frame, 1, 0, true); What happens with the code above is that the animation seems to flip from the last frame of the death sequence to the first frame of the idle sequence. Is there any way to feed the Animate function just one frame and have it position the character?

So are you suggesting that I need to use OpenGL, Leadwerks and MFC together and I can't just use Leadwerks and MFC?

Hey Rick. I don't know of anyone that enjoys using MFC, but I do know how to use it. I have used it a few times to write tools, which is what I want to do with this project. I know how to do it with OpenGL, but I want to write a ragdoll creator/editor for leadwerks. I think it would be better to use Leadwerks and MFC directly rather then using Leadwerks, OpenGL and MFC because the former sounds less bloated and more efficient. I haven't tried it yet with Leadwerks and MFC. I just wanted to see if anyone had any information or if it has been done before.

Does anyone know how to integrate Leadwerks with MFC (Microsoft Foundation Class) so that Leadwerks rendering and data structures can work with MFC?

How do you use the ControllerCrouched function? I know it is similar to the ControllerAirborne function, but with the ControllerAirborne you can apply a force to the controller to get the player to jump, but what do you have to do to the controller when the ControllerCrouched passes 0 back to the calling function?

hey wh1sp3r, thanks for the demo. I did get my preliminary implementation done late last night. here are two sets of code, one for the initialization and one the function being called by the crouching event: bool dhPlayer::Init(TVec3 pos) { TMaterial alphatest_mat, ammo_sample_mat; std::vector<int> weapon_list; str str_alphatest; if(m_vStartPosition.X == 0.0 && m_vStartPosition.Y == 0.0 && m_vStartPosition.Z == 0.0) m_vStartPosition = pos; // Create(m_vStartPosition); PositionEntity(fw.GetMain().GetCamera(), m_vStartPosition); standing = CreateController(flt(PLAYER_STANDING_HEIGHT), 12.0f, 35.0f); crouching = CreateController(flt(PLAYER_CROUCHING_HEIGHT), 12.0f); EntityType(standing, 0); SetBodyMass(standing, 85); SetBodyGravityMode(standing, 1); SetBodyDamping(standing, 50.0f, 50.0f); SetBodyFriction(standing, 50.0f, 50.0f); EntityType(crouching, 0); SetBodyMass(crouching, 85); SetBodyGravityMode(crouching, 1); SetBodyDamping(crouching, 50.0f, 50.0f); SetBodyFriction(crouching, 50.0f, 50.0f); m_iPlayerStatus = PLAYER_STANDING; player = standing; PositionEntity(player, EntityPosition(fw.GetMain().GetCamera())); EntityType(player, COLLISION_PLAYER); SetEntityKey(player, "name", "player"); luabind::module(myLuaState) [ luabind::class_<dhLuaWeaponScript>("dhLuaWeaponScript") .def(luabind::constructor<>()) .def("SetWeaponModel", &dhLuaWeaponScript::SetWeaponModel) .def("SetWeaponPosition", &dhLuaWeaponScript::SetWeaponPosition) .def("SetWeaponRotation", &dhLuaWeaponScript::SetWeaponRotation) .def("SetWeaponFireSpot", &dhLuaWeaponScript::SetWeaponFireSpot) .def("SetAttackSound", &dhLuaWeaponScript::SetAttackSound) .def("SetReloadSound", &dhLuaWeaponScript::SetReloadSound) .def("SetUseSound", &dhLuaWeaponScript::SetUseSound) .def("SetWeaponType", &dhLuaWeaponScript::SetWeaponType) .def("SetAttackAnimFunc", &dhLuaWeaponScript::SetAttackAnimFunc) .def("SetGeneralAnimFunc", &dhLuaWeaponScript::SetGeneralAnimFunc) .def("SetMaxClipSize", &dhLuaWeaponScript::SetMaxClipSize) .def("SetMaxAmmo", &dhLuaWeaponScript::SetMaxAmmo) .def("SetStartAmmoAmount", &dhLuaWeaponScript::SetStartAmmoAmount) .def("SetStartClipAmmoAmount", &dhLuaWeaponScript::SetStartClipAmmoAmount) .def("PrintWeaponMessage", &dhLuaWeaponScript::PrintWeaponMessage) .def("SetReloadDOF", &dhLuaWeaponScript::SetReloadDOF) .def("SetReloadDOFStrength", &dhLuaWeaponScript::SetReloadDOFStrength) .def("SetFireRate", &dhLuaWeaponScript::SetFireRate) ]; luabind::module(myLuaState) [ luabind::class_<dhLuaPlayerScript>("dhLuaPlayerScript") .def(luabind::constructor<>()) .def("LoadWeapon", &dhLuaPlayerScript::LoadWeapon) ]; LoadPlayerScript("abstract::player.lua"); LoadPlayersWeapon(WEAPON_FISTS); weapon_list = PlayerScript.GetWeaponList(); for(int i=0;i<weapon_list.size();i++) { LoadPlayersWeapon(weapon_list[i]); } activation_timer.Initialize(); activation_timer.AddItem(100); // For turning flashlight on and off. activation_timer.AddItem(100); // For switching light (in this case) on and off g_tCrossHair = LoadTexture("abstract::crosshairb.dds"); // new_gun.weapon_type = WEAPON_PISTOL; // m_tGunList.push_back(new_gun); // GUIHealthGroup = LoadTexture("abstract::health_group.dds"); // GUIHealthUnits[0] = LoadTexture("abstract::trans_test.dds"); // DrawImage(GUIHealthGroup, 400, 400, 156, 104); //--g_Renderer.SetCurWorld(WLD_FOREGROUND); --// // fgcam.Create(Vec3(0.0f, 0.0f, 0.0f)); // alphatest=CreatePlane(); fw.GetTransparency().SetWorld(); CreateAmmoHUD(); CreateHealthHUD(); fw.GetMain().SetWorld(); // RotateMesh(alphatest, Vec3(-90.0f, 0.0f, 0.0f)); // RotateMesh(alphatest, Vec3(0.0f, 0.0f, 90.0f)); // PositionEntity(alphatest,Vec3(1.5, -1.7, 2.5)); // ScaleEntity(alphatest,Vec3(0.5)); // alphatest_mat = LoadMaterial("abstract::alphatest.mat"); // PaintEntity(alphatest,alphatest_mat); // HideEntity(alphatest); //--g_Renderer.SetCurWorld(WLD_MAIN);--// SetEntityCallback(player, (byte*)EntityCollisionCallback,ENTITYCALLBACK_COLLISION); SetEntityCallback(player, (byte*)MessageReceiveCallback, ENTITYCALLBACK_MESSAGERECEIVE); SetEntityCallback(player, (byte*)UpdateMatrixCallback,ENTITYCALLBACK_UPDATEMATRIX); m_sJump = LoadSound("abstract::jump1.wav"); m_sGrenExplode = LoadSound("abstract::impexp_03.wav"); campivot=CreatePivot(); CreateFlashLight(); PositionEntity(campivot, EntityPosition(fw.GetMain().GetCamera())); return true; } void dhPlayer::Crouch(void) { if(m_iPlayerStatus == PLAYER_STANDING) { TVec3 pos = EntityPosition(player); m_iPlayerStatus = PLAYER_CROUCHING; player = crouching; PositionEntity(player, pos); EntityType(player, COLLISION_PLAYER); EntityType(standing, 0); SetBodyGravityMode(standing, 0); } else if(m_iPlayerStatus == PLAYER_CROUCHING) { TVec3 pos = EntityPosition(player); m_iPlayerStatus = PLAYER_STANDING; player = standing; PositionEntity(player, pos); EntityType(player, COLLISION_PLAYER); EntityType(crouching, 0); SetBodyGravityMode(crouching, 0); } SetEntityKey(player, "name", "player"); SetBodyGravityMode(player, 1); } The behaviour I am getting is not desirable. I can crouch the first time just fine but standing back up doesn't work very well. The camera slides back down to the crouching position sometimes. I was wondering if any one could suggest a better method or can see something in my code that would create a problem. Thanks in advance.

That was suggested earlier, but was wondering if anyone had gotten it working or if there was a way of doing easily through the engine. I'm sure Josh said that he was going to look into this, but I guess he has chosen not to at this point. I did start with the implementation that you suggested above and I will revisit it very soon.

Has anyone been able to get crouching to work with the Player Controller (TController)? If you have been able to could you state how you went about doing this?

I had something similar to this working in earlier version of LE, but now all I get is a black image. Here is some code: SaveBuffer(BackBuffer(),filename, 100); strcpy(g_strScreenshot, filename); g_bScreenshotMsg = true; sprintf(temp, "Saved screenshot as: %s", g_strScreenshot); AppLog(temp, 0); done=true; I am using Framewerk and LE 2.28, do I need to pass a buffer from Framewerk or is using BackBuffer still fine?

Yeah that's what I thought when it was announced that 2.3 was going to cost money. Josh did say he was going to look into some of the issues people were complaining about and fix them for 2.28, but I guess that isn't going to happen.

Are you using 2.3 at all or are you still using 2.2x?

Is Leadwerks Engine 2.28 still an active project? Will there be updates and will the issues illustrated in previous forum posts be correct or will everyone not using 2.3 be forced to migrate to it if they still want to create a project with Leadwerks?
