[Need suggestion about C++ game]

I want to create a game in which

1. I can choose Weapons and add them into player's inventory in a sperated map (call "loadout.map")
2. That loadout can be saved (player can name the saved one as "recon kit", "assault kit" etc..) or select as active loadout.
3. When a mission map is loaded, player will load saved loadout to play

Which is the best way to achieve this ? please give me a direction, and yes, C++ way.

The main question is about save and load process, should I use database ?

The line Player player2; is useless for this example. should it be removed ?

More here, I think it should be "monster" in the second red rectangle

Hi @Marcousik

Would you mind replacing 2 videos in your signature section with 2 youtube link instead ?

Somehow it is harder to find information, when your signature is to big and getting others''s attention.

Thanks

Finally, the solution is verysimple, just move the gun model far away from camera then adjust its FOV or Zoom, muhaallalala

[which one has better performance]

I would think that the simple checking of a few variables would have a small effect compared to executing a lot of code in your function.  It depends also on what type of code your executing, but the later would be more efficient.  It's also what I do in C++ to gain better performance.

Yes that function WithManyCalculation have many thing inside  thanks

[which one has better performance]

I am optimizing my game's frame per sec and wonder which way of code has better performance

function Script:WithManyCalculation()
	--A ton of code
end

function Script:UpdateWorld()
	self:WithManyCalculation()
end

and

function Script:Start()
  self.time = Time:GetCurrent()
end

function Script:WithManyCalculation()
	--A ton of code
end

function Script:UpdateWorld()
	if Time:GetCurrent() - self.time > 60 then
    	self:WithManyCalculation()
    	self.time = TIme:GetCurrent()
    end
end

[How can I make my scope like this]

You could not model the inside of the scope.  That way you can see through the backfaces of the outside mesh.  Might look okay... ?

This is a good idea but not perfect, in somecases, the scope model has detail when look from outside but some of its faces still visible inside

It is possible they might have modeled it in a way to make it appear that way, like maybe it's actually really really short.

Thanks for your suggestion. I will try it

In old COD4, they really make an ACOG scope which player can see inside of it

And then in Modern Warfare 2 or 3

when not in aiming mode, this ACOG look so strange, so what is the real technique

[How can I make my scope like this]

hmmm... I mean that scope looks like it was projected on screen only visible part of it. I will do some research

[How can I make my scope like this]

I guess there is something to do with scope model itself, but no suggestion, seems only that scope has orthor view

[How can I make my scope like this]

Yeah I will try to make one, but I wonder how did they do in game like Irsurgency sandstorm and many FPS game outthere

[How can I make my scope like this]

Lol this is my blog, mate.

I want to improve some frame per second by not using another camera to render to texture.

[How can I make my scope like this]

This is from Irsurgency Sandstorm

And this is mine

How can I make my scope model look Orthographic Projection like that

[Script:Update()/Draw()/DrawEach() Explaination]

Draw() and UpdateWorld() behaviors are the same when I put some code inside them.

"Script:Draw(): This is called the first time an object is rendered during a scene render." It sounds the same as UpdateWorld() to me. Is scene rendered each frame ?

[Script:Update()/Draw()/DrawEach() Explaination]

After reading document page here (https://www.leadwerks.com/learn?page=Tutorials_Lua-Scripting_Introduction-to-Lua)

I still can't figure out those functions usage.

Can anyone explain more clear ? 

[Icon of Editors]

sometimes I need to put pivot into some small object models but their icons are too big, is it posible to make these icons (camera, pivot, particles etc) keep their size at the same while zoom in and zoom out in editor ?

Look at this mess I have

[which way better]

I wonder how the performance is in 2 ways of using variables in lua.

Which one is better when there are many of pivots which can be attached script, each script has its own "self." variables

Method 1: Use table for everything

Script.table = {} --create masster table of scripts

function Script:Start()
  table.category1 = {}
  table.category1.variable_1 = somevalue
  table.category1.variable_2 = somevalue
  ...
  table.category1.variable_n = somevalue

  table.category2 = {}
  table.category2.variable_1 = somevalue
  table.category2.variable_2 = somevalue
  ...
  table.category2.variable_n = somevalue
end

Method 2: Use Script.variable only

Script.valuable_1 = something
Script.valuable_2 = something

function Script:Start()
	self.valuable_3 = something
	self.valuable_4 = something
	...
	self.valuable_n = something
end

 

[A math question]

Thanks macklebee, your explaination is clear as daylight ! so detail. Finally I did it,

It took time to understand math in English ^^

[Turbo's new bone/animation system and ragdoll physic]

I remember first few months of using Leadwerks, I can implement a ragdoll in character bone system (using Joints). I love ragdoll physics when shooting some humanoid target, I guess I will use the same technique to my current game.

ragdoll is possible for current bone system (each bone is an entity) but how about Turbo ? Does that mean "NO HOPE" for ragdoll physic for new system.

 

 

 

[A math question]

Just now, macklebee said:

Should be possible as it gives the orientation of the plane. 

It sound sweet, then please help me with a simple fomula or steps to archive my calculation

[A math question]

Oh I see, Thanks for pointing it out.

If there is one more vector (a) which have known Orange point position, and it is on the same plane with vector u and w (as figure image),
and a new beta angle which = 1/2 * alpha angle

will it be posible to calculate the Black position ?

[A math question]

Here you are

[A math question]

Thanks for you reply

All of Red, Blue, Black are in 3D and alpha is not a constant

Can you help me with a formula, it is bad that I can't remember these basic formulas for triangle calculation

• red:GetPosition(true)
• blue:GetPosition(true)
• u:Length()
• alpha
• black:GetPosition(true) = ???

[A math question]

I am not really good at math,

Can you show me how to solve this

Known:

• Position of Red and Blue (in Vec3)
• Length of edge between Blue and Black,
• Alpha Angle (in Degree)

I want to get the position of Black (in Vec3)

Thanks
