I discovered that there can only be one eventqueue in leadwerks. I wanted local eventqueue instances, so I created a lua based version of EventQueue called EventQueueEx It is initialized as such: MyQueue = EventQueueEx:Create() It is used EXACTLY the same as the Leadwerks version.

Hey there, Just wondering if there is a place to find scripts made by others that are ready to use? I know Leadwerks comes with some, but I'd like to play around with some others too. I've had a quick look around, can't seem to find any or maybe I just missed them all completely. Thanks

This is a query more than anything. As I read the documentation both Script:UpdateWorld() and Script:UpdatePhysics() are both initiated by a single call to World::Update(). In fact the physics is a child of world and is always(?) invoked. So it appears that the separation is more a conceptual one rather than a functional one. The only reason I can think of is by putting all physics in UpdatePhysics then if (I'm not sure) that is invoked first you would know that all physics updates have been applied before you do any other world level checks/logic. So is that it or am I missing something important? I'm feeling rather dense today.

I've been staring at this code for way too long and now I need different brains to look at it. This is the beginnings of a 3rd person character controller. I am now working at adding mouse look features but there seems to be a bug when the camera is at specific angles, notable y45 and y270. At those specific locations the camera glitches out. I will give it another try tomorrow, and no I don't want to create a pivot and anchor the camera to it and spin that --[[ Title: Third Person Controller Author: Einlander Start Date: 1-30-2016 Version: .01 Description: Script to control Player in 3rd person with keyboard and mouse Notes: This script is designed to mimic classical 3rd person game controls: *Look with mouse *Move with WASD *Follow Player as they move ]]-- Script.Cam =nil --entity "Camera" Script.moveSpeed = 2.5 --float "Move Speed" Script.speedMultiplier = 1.5 --float "Run Multiplier" Script.strafeSpeed = 4 --float "Strafe Speed" Script.jumpForce = 8 --float "Jump Force" function Script:Start() self.input={} self.unitangle = Vec3() self.anglemagnitude = nil end --[[ function Script:UpdateWorld() end --]] function Script:UpdatePhysics() local movex=0 local movez=0 self.input[0]=0 self.input[1]=0 local playerMovement = Vec3() -- I learned the boolean shortcuts from my years programming on a Casio Graphing Calculator self.input[1] = self.input[1] + ((window:KeyDown(Key.W) and 1 or 0) - (window:KeyDown(Key.S) and 1 or 0)) self.input[0] = self.input[0] - ((window:KeyDown(Key.A) and 1 or 0) - (window:KeyDown(Key.D) and 1 or 0)) playerMovement.z = self.input[1] * self.moveSpeed -- Strafing playerMovement.x = self.input[0] * self.moveSpeed if self.carryingEntity == nil and window:KeyDown(Key.Shift) then playerMovement.z = playerMovement.z * self.speedMultiplier -- Run while Strafed -- playerMovement.x = playerMovement.x * self.speedMultiplier end local jump = 0 if window:KeyHit(Key.Space) and self:IsAirborne() == 0 then jump = self.jumpForce playerMovement = playerMovement * 1.6 end self.entity:SetInput(0, playerMovement.z, playerMovement.x, jump , false, 1.0, 0.5, true) local startpos = Vec3( self.entity:GetPosition(true).x, self.entity:GetPosition(true).y + 5 , self.entity:GetPosition(true).z -5 ) -- y distance to get above players head, z - distance we want from player local endpos = Vec3() -- rotate the starting position (where the camera is at) around the player position if self.rot == nil then self.rot = 0 end self.rot = self.rot+.5 local finalpos = Vec3() finalpos = self:rotateX3D({startpos},self.entity:GetPosition(true) , 0)[1] finalpos = self:rotatePointY({finalpos},self.entity:GetPosition(true) , self.rot)[1] -- when self.rot ~ 45 or 270 it flips just for that 1 angle -- set camera at the final rotated positon self.Cam:SetPosition(finalpos) -- make camera look at player local lookAt = self:LookAt(self.entity:GetPosition(true)) lookAt.z = 0 -- THIS LINE IS IMPORTANT.

Hey so I have been messing around with the map changer that came with leadwerks (copied it and renamed it so I have the original still) to choose between random seed maps (initial starting areas the rest is generated) but when it tried to change maps it crashes or gives me a lua stack overflow issue. Is there something wrong with my code? Here it is. --[[ This script will act as a trigger to change the current map. Place this at the end of your map to make the player progress to the next level. ]]-- Script.mapname={} Script.mapname[0] = "" --string "Map Name" Script.mapname[1] = "" --string "Map Name" Script.mapname[2] = "" --string "Map Name" Script.mapname[3] = "" --string "Map Name" function Script:Start() self.enabled=true math.randomseed(Time:Millisecs()) math.random();math.random();math.random(); self.counter = 0 end function Script:Collision(entity, position, normal, speed) changemapname = math.random(0,3) end function Script:Enable()--in if self.enabled==false then self.enabled=true self:CallOutputs("Enable") end end function Script:Disable()--in if self.enabled then self.enabled=false self:CallOutputs("Disable") end end

I believe this is a bug. When I put a pick-up code on an item (weapons collectables ect) and choose the mesh for it to represent, the (in case of the weapons) mesh chosen will show close to the pick-up mesh. Also if you have a weapon equipped then the mesh doesn't disappear when you pick up the pick-up. here is a pic of what appears with the pick-ups ( a few steps away)

Hello everyone, I am creating a game where the player has to use physics to navigate the level, such as stacking objects to create stairs to get to a point, etc. In said game, the player can accidently drop objects off the level or get them destroyed by other forces. I would like to implement a feature where the player can hit a key and the level and all scripts, lighting, etc. is reloaded. This code must be in C++. How can I do this? Please help. Thanks.

It's the holiday season again. As the forest air reaches freezing temperatures, I break out the ice shaver for my windshield. It's a time for celebrating family, sharing thanks for what we have, and behavior sets. That's right, fuzzy-logic for AI in-game. Since the world designers for the game won't have access to the direct behaviors, (nor the programming skills to code such things) I've managed to find some use for the custom Entity keys on objects in the Sandbox! Each entity will have actions assigned to a set of situations. Think of it like 'IF' statements that world builders have access too. This Enumeration of behaviors gives the designers flexibility to alter the NPCs actions easily within the sandbox. Global preset behavior collections, or custom sets per situation. For example, and NPC who follows the player may have something similar to this DefaultTarget = Player DefaultAction = FollowTarget Now if the NPC needs to defend the player... GuardTargetAction = KillAttacker Or... GuardTargetAction = HealTarget
