Ok Lumooja, I'll try...thx

Yes, the wheels continues with the speed it was before I place in new position. But I used that Lumooja said, it's working. The only problem is that if the car is running in a curve, and while accelerate, if is positioned for a new position, the car go, stay stopped, but is turning to side that was turning before go to new position. I can't explain better, but if u run this script, go to front, and right, in same time, it's will turn to right, when get a great velocity, press SPACE, and you will see whats happened.

An example, of what I want. This is the script of driver.lua, of viperscout. I just add this IF in main loop: require("Scripts/constants/keycodes") require("Scripts/linkedlist") require("Scripts/filesystem") require("scripts/math/math") require("scripts/constants/engine_const") FlushKeys() HideMouse() local camera = fw.main.camera chassis=LoadModel("abstract::vehicle_viperscout.gmf") carobject=objecttable[chassis] car=carobject.vehicle if car==nil then Notify("Vehicle object not found.",1) chassis:Free() return end chassis:SetPosition(TFormPoint(Vec3(0,-1,10),fw.main.camera,nil)) chassis:SetRotationf(0,camera.rotation.y+180.0,0) --Variables local dx=0.0 local dy=0.0 local camerapitch=camera.rotation.x local camerayaw=camera.rotation.y local move=0.0 local strafe=0.0 local steering = 0.0 local torque = 0.0 local steerlimit = 30.0 local steerrate = 2.0 local steerangle=0.0 MoveMouse(Round(GraphicsWidth()/2),Round(GraphicsHeight()/2)) while KeyHit(KEY_ESCAPE)==0 do --Camera look gx=Round(GraphicsWidth()/2) gy=Round(GraphicsHeight()/2) dx=Curve((MouseX()-gx)/4.0,dx,3.0/AppSpeed()) dy=Curve((MouseY()-gy)/4.0,dy,3.0/AppSpeed()) MoveMouse(gx,gy) camerapitch=camerapitch+dy camerayaw=camerayaw-dx camerapitch=math.min(camerapitch,90) camerapitch=math.max(camerapitch,-90) fw.main.camera:SetRotationf(camerapitch,camerayaw,0,1) local tirespeed=-(KeyDown(KEY_UP)-KeyDown(KEY_DOWN))*2.0 car:AddTireTorque(tirespeed,0) car:AddTireTorque(tirespeed,1) car:AddTireTorque(tirespeed,2) car:AddTireTorque(tirespeed,3) steermode=0 if KeyDown(KEY_RIGHT)==1 then steermode=steermode-1 end if KeyDown(KEY_LEFT)==1 then steermode=steermode+1 end if steermode==1 then steerangle=steerangle+4.0*AppSpeed() elseif steermode==-1 then steerangle=steerangle-4.0*AppSpeed() else if steerangle>0 then steerangle=steerangle-4.0*AppSpeed() if steerangle<0.0 then steerangle=0.0 end else steerangle=steerangle+4.0*AppSpeed() if steerangle>0.0 then steerangle=0.0 end end end steerangle=Clamp(steerangle,-25,25) car:SetSteerAngle(steerangle,0) car:SetSteerAngle(steerangle,1) fw:Update() local campos=TFormPoint(Vec3(0,1,0),chassis,nil) fw.main.camera:SetPosition(campos) fw.main.camera:Move(Vec3(0,0,-10)) local t=TFormVector(Vec3(0,0,1),camera,chassis) a=-math.deg(math.atan2(t.x,t.z))+180.0 carobject.turret:SetRotationf(0,CurveAngle(a,carobject.turret.rotation.y,10.0/AppSpeed()),0) chassis:Hide() local pick = LinePick(campos,camera.position,0.5,COLLISION_PROP) chassis:Show() if pick~=nil then camera:SetPosition(pick.position) end if(KeyHit(KEY_SPACE)==1) then chassis:SetPosition(Vec3(0,0,0)) end fw:Render() Flip(0) end chassis:Free() chassis=nil camera=nil ShowMouse() if(KeyHit(KEY_SPACE)==1) then chassis:SetPosition(Vec3(0,0,0)) end If you are running with the car normally, and press SPACE, the car is back to position (0,0,0), but continue with velocity. I want to the car back to pos(0,0,0), and stay stopped, ie, without force..

The body is scalled together with the mesh, but like Rick said, not work correctly. In lua dont have some functions to work with directories? create file, delete file...

A while ago I made this script, for now I using this.. require("scripts/class") local class=CreateClass(...) function class:InitDialog(grid) self.super:InitDialog(grid) group=grid:AddGroup("Scale") group:AddProperty("Scale",PROPERTY_FLOAT,"1,4,2") group:Expand(1) end function class:CreateObject(model) local object=self.super:CreateObject(model) object.model:SetKey("scale","1") function object:SetKey(key,value) if key=="scale" then self.scale=tonumber(value) model:SetScalef(self.scale,self.scale,self.scale,0) else return self.super:SetKey(key,value) end return 1 end end

Just press F4

Yes, eg: the car is moving normally, and in certain moment, it's moved to position (0,0,0). But I want it is positioned, and stay stopped in new positioned. Whats occurring, is that it's being positioned and continues going to front, because of force applied in the wheels.. I'm using C/C++

Hi, how I can use a shader created for me? For sample, a blur shader. I want to active in certain moment, and desactive in some seconds after.

I'm with a doubt. When my car vehicle get out the road, it pass over a trigger, that return back the car to road in certain position. The problem, is that when it pass in some trigger, it have a velocity, and when back to center road, the velocity coninue, but I need that the car back to the road stopped, like in all game cars, when the player get out from road. I used: SetBodyVelocity(car,Vec3(0,0,0),0); SetBodyOmega(car,Vec3(0,0,0),0); The car back to road stopped, but after millisecs for sample, it begins to turn to right or left randomly, like if have some forces applying over car. What function I can use to "reset" the force in vehicle, and torques in tires?! thx

Sad... I did some searches too, and see that in the own Newton's forum is talked about it. Well, I'll try simulate this with animations "pre-made", or use other model in the place. However, thanks Josh for feedback..

In lua there is a method called GetTarget(int linkIndex) which possibilities to access the links created in the sandbox. What is the c/c++ equivalent command?

Not just the shader, but the scripts to get the images, and send to the shader.

Hello guys... As I posted in other topic, I'm trying create a cloth system, to apply in a model. I created a rope with node and joints between it. The nodes I parented in bones, and "apply" physics them. My first problem I was solved, that the performance problem, so I did that talked in other topic, in slice in areas, and go activating the mass... Well, the problem now, is when the model falls, the nodes are "fighting", and not stop, as if are trying enter into the other.. Have some function to solve this...or some way??? A video, of whats happening:

Hi peoples. I'm having a big problem with the performace, and dont know to solve. I created a model of a grid. I wanna it have reaction with the physics if the car collide with it, or bursts. So far so good, I used there rope system, and convert to Lua in the model. The Problem, this is a scene to race game, have a lot models like it in the road. So when begin the scene, the FPS start extremely low. Cause at the start, the physics begins working in ever models. Have someway to begins with some model physics, stoped? And begins to work, just when the camera is near? Or some other way, to could optmize the performance of model physics reaction? Below, is the code that I'm using. Just to be clear, inside model, have some bones: "bones1","bones2"....until the 14, that is parented to physics nodes. require("scripts/class") require("Scripts/constants/collision_const") local

Thanks Josh...im was trying somethings here, and it working now...

Hi, i'm trying do a rope system, and I found this topic: http://leadwerks.com...h__1#entry23004 And I used the example of MasteR. Had some bugs, and I fix it. But the problem that I'm having, I can't move the first node, like move a Entity. It move, but have a little "delay" in your movement. I dont know if is cause he's as TBody. I tried use CalcBodyVelocity() and AddBodyForce() too, but I dont had luck. My code is this, i need so much this. Just for clarity, I wanna use this as a cloth fence, where the extremities will fixed, and in the center will fall. Then the nodes of rope, will be the "bones" to model. But this model will move, then the rope with nodes need move together, in the same position. Here is my code, if need, I try explain in other way...thanks [Cable.h] #include "leo.h" class CPhysicsCable { private: int pNodes; TVec3 pStartPoint; TVec3 pEndPoint; float pThickness; bool pAttached; float pLength; TVec3 nodePos; TVec3 Calc; public: TEntity *pBodyNodes; TEntity *pMeshNodes; TVec3 TempPos; TEntity start; TEntity end; TEntity firstJoint; TEntity pPivotStart; TEntity pPivotEnd; CPhysicsCable(TVec3 aStart, TVec3 aEnd, float aThickness, int aNodes, bool aAttached,TEntity aPivotStart,TEntity aPivotEnd) { pNodes = aNodes; pStartPoint = aStart; pEndPoint = aEnd; pThickness = aThickness; pAttached = aAttached; pLength = 0.0; pMeshNodes = new TEntity[pNodes]; pBodyNodes = new TEntity[pNodes]; pPivotStart = aPivotStart; pPivotEnd = aPivotEnd; Create(); } void Create() { start = CreateBodyBox(0.1, 0.1, 0.1, 0); end = CreateBodyBox(0.1, 0.1, 0.1, 0); PositionEntity(start, pStartPoint); PositionEntity(end, pEndPoint); pLength = EntityDistance(start, end)/pNodes; pMeshNodes[0] = CreateCylinder(6, 1, 0); TMaterial material = LoadMaterial("abstract::Cable_node.mat"); PaintEntity(pMeshNodes[0],material); ScaleEntity(pMeshNodes[0], Vec3(pThickness, pLength, pThickness)); pBodyNodes[0] = CreateBodyBox(pThickness, pLength, pThickness); SetBodyMass(pBodyNodes[0], 0.1); EntityType(pBodyNodes[0], 1); EntityParent(pMeshNodes[0], pBodyNodes[0]); PositionEntity(pBodyNodes[0], pStartPoint, 1); PointEntity(pBodyNodes[0], end, 1); PointEntity(pBodyNodes[0], end, 2); PointEntity(pBodyNodes[0], end, 3); TurnEntity(pBodyNodes[0], Vec3(90.0, 0.0, 0.0), 0); MoveEntity(pBodyNodes[0], Vec3(0.0, pLength/2.0, 0.0), 0); firstJoint = CreateJointBall(start, pBodyNodes[0], pStartPoint, Vec3(0.0, 0.0, 0.0)); SetBallJointLimits(firstJoint, 180.0, 180.0, 180.0); for(int i=1; i<pNodes; i++) { pMeshNodes[i] = CopyEntity(pMeshNodes[0]); pBodyNodes[i] = CopyEntity(pBodyNodes[0]); EntityParent(pMeshNodes[i], pBodyNodes[i]); PositionEntity(pBodyNodes[i], EntityPosition(pBodyNodes[i-1]), 1); PointEntity(pBodyNodes[i], end, 1); PointEntity(pBodyNodes[i], end, 2); PointEntity(pBodyNodes[i], end, 3); TurnEntity(pBodyNodes[i], Vec3(90.0, 0.0, 0.0), 0); MoveEntity(pBodyNodes[i], Vec3(0.0, pLength, 0.0), 0); nodePos = EntityPosition(pBodyNodes[i]); TEntity nodeJoint = CreateJointBall(pBodyNodes[i-1], pBodyNodes[i], Vec3(nodePos.X, nodePos.Y, nodePos.Z+(pLength/2.0)), Vec3(0.0, 0.0, 0.0)); SetBallJointLimits(nodeJoint, 0.0, 180.0, 180.0); } if(pAttached==1) { TEntity lastJoint = CreateJointBall(pBodyNodes[pNodes-1], end, pEndPoint, Vec3(0.0, 0.0, 0.0)); SetBallJointLimits (lastJoint, 180.0, 180.0, 180.0); } } void Update() { PositionEntity(start,EntityPosition(pPivotStart)); }; [main] #include "engine.h" #include "Cable.h" int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd ) { Initialize() ; RegisterAbstractPath("D:/Projetos/Rally"); SetAppTitle( "Cables" ) ; Graphics( 800, 600 ) ; AFilter() ; TFilter() ; TLight light; TMesh ground; TMaterial material; TFramework framework=CreateFramework(); TLayer layer = GetFrameworkLayer(0); TCamera camera=GetLayerCamera(layer); light=CreateDirectionalLight(); RotateEntity(light,Vec3(45,45,45)); PositionEntity(camera,Vec3(0,0,-2)); float sx = -2; float sy = 1; float sz = 2; float ex = 2; float ey = 1; float ez = 2; TEntity c=CreateCube(); PositionEntity(c,Vec3(sx,sy,sz)); ScaleEntity(c,Vec3(0.2,0.2,0.2)); TEntity c2=CreateCube(); PositionEntity(c2,Vec3(ex,ey,ez)); ScaleEntity(c2,Vec3(0.2,0.2,0.2)); TVec3 startPos = Vec3(sx,sy,sz); TVec3 endPos = Vec3(2,1,2); CPhysicsCable* Cable = new CPhysicsCable(startPos,endPos,0.1,50,1,c,c2); TEntity sphere = CreateSphere(); ScaleEntity(sphere,Vec3(0.3,0.3,0.3)); TVec3 CalcPos; SetBodyVelocity(Cable->pBodyNodes[0],Vec3(100,100,100)); // Game loop while( !KeyHit() && !AppTerminate() ) { if( !AppSuspended() ) // We are not in focus! { //Move if(KeyDown(KEY_RIGHT)==1){ sx = sx + 0.1; ex = ex + 0.1; } if(KeyDown(KEY_LEFT)==1){ sx = sx - 0.1; ex = ex - 0.1; } PositionEntity(c,Vec3(sx,sy,sz)); Cable->Update(); // Update timing and world UpdateAppTime(); UpdateWorld(AppSpeed()) ; // Render RenderFramework(); UpdateFramework(); //Texts DrawText(10,25,"%f",(EntityPosition(Cable->pPivotStart)).X); // Send to screen Flip(0) ; } } // Done return Terminate() ; }

cool..I dont seen this function. Thanks Lumooja..

Hi.. I need use this function: http://newtondynamics.com/wiki/index.php5?title=NewtonBodyGetMatrix I searched in Wiki something seems, but I only found the GetEntityMatrix(), and nothing to use in a Body entity. Have some command like this? I need use in LUA if possible..

So, I have three trigger types: 1: to determine the progress of player in the scene. 2: THIS of my example, that is to activate some fx, like audio fx, post process etc... 3: a fence to limit the car in the road, when the car over this trigger, he is brought back to road. In the car player script have a function Collide, when it collides with some trigger, is sent a menssage to c++ code(ReceiveMessage()) with the name of the trigger collided. For this, the naming convention. If it collided in the trigger type 3 for sample, is sent this message: "trigger3_4", so, the car will positioned in the last trigger1 that has been collided. In the case of Trigger2, in the second number("trigger2_x_y"), the "y", is the fx(if 1:sound x, if 2: postfx x....etc), but the first number, the "x", is need be different, cause when the c++ receive the message with the name, is stored in a array, and "x" is the index of this array. I tried explain better my problem, my english no help much...hehe But if need, I try explain in other way..

anyone? I really need it.. One other doubt, I need use this function: http://newtondynamics.com/wiki/index.php5?title=NewtonBodyGetMatrix I searched in Wiki something seems, but I only found the GetEntityMatrix(), and nothing to use in a Body entity. Have some command like this? And if possible, to use in LUA..

Hi peoples... Im having the follow problem: I have a model called trigger2. Always that I create a new trigger2 in editor, it is called as "trigger2_x_y", where 'x' is the ID, 1,2,3,4....and 'y' is the fx that will received, that is set in own properties. I.e, if I create the first 'trigger2' in scene, with the fx set to '0', it name as "trigger2_0_0", if I create other in the scene, it is named as "trigger2_1_0", and so on. The problem is each trigger2 that I create in the scene, is add a value in the first trigger too, and not only in last trigger. If have 10 trigger in the scene, the first trigger, is named as "trigger2_0_1_3_4_5_9_5_6....".. I think that something with the global variables in the own class model. But dont know how solve this.. This is the trigger code: require("scripts/class") local class=CreateClass(...) function class:InitDialog(grid) self.super:InitDialog(grid) group=grid:AddGroup("Tipo") group:AddProperty("tipofx",PROPERTY_CHOICE,"0,1,2,3,4,5,6,7,8,9,10","Tipo Fx") group:Expand(1) end function class:CreateObject(model) local object=self.super:CreateObject(model) local mesh=nil object.model:SetKey("tipofx","0") if(n~=nil) then n=nil end if(n2~=nil) then n2=nil end if(id~=nil) then id=nil end if(id2~=nil) then id2=nil end id=0 id2=0 function object:SetKey(key,value) if key=='tipofx' then --overrides color setting n2 = n.."_"..value object.model:SetKey("name",n2) end return 1 end function object:Update() if debug==1 and mesh==nil then mesh=LoadModel("abstract::pista1_models_triggers_trigger3_trigger3mesh.gmf",model) model:SetShadowMode(0,1) mesh:SetKey("name",model:GetKey("name")) elseif debug == 0 and mesh ~= nil then mesh:Free() mesh=nil end if(id2==0) then n=object.model:GetKey("name") n2 = n.."_"..object.model:GetKey("tipofx") n=object.model:GetKey("name") local fx=object.model:GetKey("tipofx") local n2=n.."_"..fx self.model:SetKey("name",n2) id2=1 end end function object:Collision(entity,position,normal,force,speed) if chave==0 then Trigger() chave=1 end end function object:Free(model) if mesh~=nil and debug==0 then mesh:Free() mesh=nil end end end

Very nice, thanks for sharing! You will add support to skybox?? Would good, if can set some texture cubemap combined with the day/night.

Hello, How i can do LOD models, of an animated model? I use the 3Ds max to export, i need rig the LOD version too? thanks

Yes, the EntityPosition(). You can also do this: TVec3 planetpos = EntityPosition(planet); TVec3 objpos = EntityPostion(obj); //x while(objpos.x<planetpos.x){ MoveEntity(obj,Vec3(-1,0,0); } while(objpos.x>planetpos.x){ MoveEntity(obj,Vec3(1,0,0); } //y while(objpos.y<planetpos.y){ MoveEntity(obj,Vec3(0,-1,0); } while(objpos.y>planetpos.y){ MoveEntity(obj,Vec3(0,1,0); } //z while(objpos.z<planetpos.z){ MoveEntity(obj,Vec3(0,0,-1); } while(objpos.z>planetpos.z){ MoveEntity(obj,Vec3(0,0,1); } not a good solution, but it can work.

Yes ZioRed, I have tried this, but the problem continue =/ I have tried model by model.. cool this, because now I depend this, for test the game out editor. The Josh have a preview to when will fix it?
