    Adding A Force in Lua

    in General Discussion

    Posted

    Thanks Rick, but that really wont work for the desired effects, as the forces need to continue through so many frames.

     

    We come a long way with lua; from no-where to a full but basic AI & Animation control. really tho I think we need to use c++.

     

    One thing we found with LUA is it runs differently different times, sometimes crashing editor sometimes not.>>really wired.

    We will share all our models and examples when we can upload here so you can try yourself.

     

    Do you find problems with LUA?

    Especially with playing sounds!!

    C++ Keeping it tidy

    in General Discussion

    Posted

    I see lots of you members are with it when it comes to programming in c++.

     

    The examples given seem messy and basic. I wanted to tidy it up I realise you must declare world,cam,buffers ect so I added the vars at the top and made some functions to crete cam and load level.

     

    When it compiles I get warnings about the possibility of accuracy loss from the following vars

     

     

    IS THIS EXCEPTABLE and or THE RIGHT WAY ??

    //Global Vars

    TCamera fgcam;

    TLight light;

    TVec3 camrotation;

    TEntity campiv;

    TEmitter fire;

    TWorld foreground;

    TCamera cam;

    TBuffer gbuffer;

    TBuffer lightbuffer;

     

     

    But it compiles and when I run it it crashes out.

    Here is the full code please some1 take a second to help and maybe give a example,

    • Your probably familiar with this one,its from the Heat/Fire example.

     

    #include "engine.h"

    #include <iostream>

    Help US Do Decals

    in General Discussion

    Posted

    We Get Violation code, AND IT SHUTS DOWN.

    Please help.

     

    I have this code added into my bullet.lua and use the pick it does just before terminating its self with a emitter.

     

    --Add Decal

    This bit at tob of bullet.lua

    bulletholemat = ("abstract::bulletholemat.mat")

     

    bullethole=CreateDecal(pick.surface,TFormPoint(pick.position,nil,pick.entity), 5.0/16.0,30)

     

    EntityParent(bullethole,mesh,0)

    PaintEntity(bullethole,bulletholemat)

    AddMesh(bullethole, pick);

    FreeEntity(bullethole)

    The Windmill Example Script Problem

    in General Discussion

    Posted

    I tried the EntityNew={} ver

    That gave me a error with inherit = nil???

     

    The following Script dont work, either

     

    if any one can help me rotate the blades that will be great.

     

    --Include the base script for all classes

    dofile("Scripts/base.lua")

     

     

    --Some global sounds we will use for all instances

    squeak={}

    squeak[0]=LoadSound("abstract::squeak_1.ogg")

    squeak[1]=LoadSound("abstract::squeak_2.ogg")

     

     

    --This function builds the interface for the properties editor

    function InitDialog(grid)

     

    --Add the base interface for all classes

    base_InitDialog(grid)

     

    --Now we can add our own custom properties

    group=grid:AddGroup( "Windmill" )

    group:AddProperty( "spinspeed","|0,4",PROPERTY_FLOAT,"Spin Speed")

    group:Expand(1)

     

    end

     

     

    --Spawn function for creating new instances

    function Spawn(model)

    local entity=base_Spawn(model)

     

    --Retrieve a few limbs we will use later

    entity.blades=model:FindChild("windmill_blades")

    entity.base=model:FindChild("windmill_housing")

    entity.model:SetKey("spinspeed","1")

     

    --An update function for one instance. Declaring the function as part of the entity table allows us to use "self" for the table

    function entity:Update()

     

    --Although these limbs should always be present, it"s a good idea to add a check to make sure they exist before using them

    if self.blades~=nil then

    self.blades:Turnf(0,tonumber(self.model:GetKey("spinspeed"))*AppSpeed(),0,0)

    end

     

    if self.base~=nil then

     

    --Make the base sway slightly

    angle=math.sin(AppTime()/2000.0)*5-15

    angle=angle+math.cos(AppTime()/500.0)*2

    self.base:SetRotationf(0,0,angle,0)

     

    --Make the base squeak

    lasttime=tonumber(self.model:GetKey("lastsqueaktime","0"))

    if (AppTime()-lasttime>8000) then

    self.model:SetKey("lastsqueaktime",AppTime()+math.random(0,5000))

    self.base:EmitSound(squeak[math.random(0,1)],50,1,0)

    end

    lasttime=tonumber(self.model:GetKey("lastsheeptime","0"))

     

    end

     

    end

     

    end

     

     

    --Update function, called during every UpdateWorld()

    function Update(world)

    if world==world_main then

    local model,entity

    for model,entity in pairs(entitytable) do

    if model.world==world then

    entity:Update()

    end

    end

    end

    end

    Creating a .DDS Glass Texture With Alpha.

    in General Discussion

    Posted

    Hi there, I'm making a Game in Leadwerks 2.3 and am having trouble making my Glass.DDS transparent

     

    I am using Photoshop CS5 with the N-vidia DDS Plugin

    I Edited the .PNG file adding an Alpha Channel. I then Made the Whole alpha channel black and then exported it as a DXT5 (Reccomended) and In the game it is not Transparent.

     

    I Also generated Mip Maps in the plugin and Tried flattening the image also. Still it doesn't work.
