Maybe so?

Pseudocode:

local distance=self.Object1:GetPosition():DistanceToPoint(self.Object2:GetPosition())
local distancei=math.floor(pos)--or Math:Round(pos)

context:DrawText("Distance: "..tostring(distancei),2,26)

String format: https://stackoverflow.com/questions/57950030/wow-rounding-to-two-decimal-places-in-lua

Quote

Here's an example using all the options: string.format("%x6.2f", 2.264)

From left to right:

% marks the start
x tells it to pad right with xs
6 tells it the whole thing should be 5 characters long
.2 tells it to round (or pad with 0s) to 2 decimal places
So, the result would be xx2.26

Maybe somehow attach to the quadratic Bezier points?

Tell me how to get a similar result, for bending fishing rods under load?

Hi!

Vehicle Physics

It would be cool to add Joint:Wheel! Or give the ability to set the speed separately, for each of the wheels (example SetAcceleration(gas,tireIndex)). Аnd to individually rotate each of the wheels (example SetSteering(steering, tireIndex))!

Sorry for my bad English(

Hi Josh,

A couple of years ago I made my dedicated server (app) for minecraft=), there for interception from the console I used pipes. But, this is works only in windows.

#include <windows.h>

#include <string>
#include <stdio.h>

#pragma warning(disable : 4996) // For GetVersionEx

#define bzero(a) memset(a,0,sizeof(a))

Hi Josh! Maybe this will help:

Code from here: http://xopendisplay.hilltopia.ca/2009/Mar/

int utf8toXChar2b(XChar2b *output_r, int outsize, const char *input, int inlen){
int j, k;
for(j =0, k=0; j < inlen && k < outsize; j ++){
	unsigned char c = input[j];
	if (c < 128)  {
		output_r[k].byte1 = 0;
		output_r[k].byte2 = c; 
		k++;
	} else if (c < 0xC0) {
		/* we're inside a character we don't know  */
		continue;
	} else switch(c&0xF0){
	case 0xC0: case 0xD0: /* two bytes 5+6 = 11 bits */
		if (inlen < j+1){ return k; }
		output_r[k].byte1 = (c&0x1C) >> 2;
		j++;
		output_r[k].byte2 = ((c&0x3) << 6) + (input[j]&0x3F);
		k++;
		break;
	case 0xE0: /* three bytes 4+6+6 = 16 bits */ 
		if (inlen < j+2){ return k; }
		j++;
		output_r[k].byte1 = ((c&0xF) << 4) + ((input[j]&0x3C) >> 2);
		c = input[j];
		j++;
		output_r[k].byte2 = ((c&0x3) << 6) + (input[j]&0x3F);
		k++;
		break;
	case 0xFF:
		/* the character uses more than 16 bits */
		continue;
	}
}
return k;
}

And convert char* to wchar_t

wchar_t * filename= L"C:\\test";
char* c = (char*)filename;

Shouldn't it be 4 vertex 2 triangle? You would re-use a couple of vertices.

Looks good btw!

I'll give it a test

Yes, you are absolutly right. But I do not know for what reason I do not make the indexes.

Thanks for test Brutile!

The error due to lack of microsoft visual c++ 2015 redistributable.

Update:

Added ebo

const float rect[] =
{
 x, y, 0.0f, 0.0f, 0.0f,
 x + width, y, 0.0f, 1.0f, 0.0f,
 x, y + height, 0.0f, 0.0f, 1.0f,
 //x, y + height, 0.0f, 0.0f, 1.0f,

1606 sprites! One sprite 6 vertex 2 triangle.

This is my simple 2D "engine", I may be selling it for $1.000.000, and buy a graphics card for Leadwerks Engine .

Need your help in testing. I want to make sure that not only works for me.

A simple example of a multiple text.

function App:Start()
  self.maxTextWidth = 128
  self.sourceText = "Text"
  self.tempText = ""
  self.text={}

  self.lineCount = 0


  for w in string.gmatch(self.sourceText, "[%p%a%d]+") do

        local temp1 = string.reverse(self.tempText)
        local temp2 = string.sub(temp1, 1, string.find(temp1," "))
        temp2 = string.reverse(temp2)

        --Add new line to list.
        self.text[self.lineCount] = temp3
        self.lineCount = self.lineCount + 1
        self.tempText = "" 

        --Now we can add the last word to new line.
        self.tempText = self.tempText..temp2.." "..w

  end
  self.text[self.lineCount] = self.tempText

Problem here:

button.defaultfont = context:GetFont()

It works:

button.defaultfont = Font:Load("Fonts/Arial.ttf",15)

March 31, 2015

Hi! I cannot understand how to use your font for button. And then use a standard font.

--Font
local context = Context:GetCurrent()
button.font = Font:Load("Fonts/Test.ttf",32) --Custom
button.defaultfont = context:GetFont() --Arial
button.color = Vec4(1.0)

Pay attention! I do not release fonts from memory.

function Button:Draw()
  local context = Context:GetCurrent()
  local window = Window:GetCurrent()
  if self.enable then
     if self.visible then
        context:SetBlendMode(Blend.Alpha)

        --Set user font
        if self.font then context:SetFont(self.font) else self.font = self.defaultfont end

        context:DrawText(self.title,25,25)

        --Set default font
        context:SetFont(self.defaultfont)

        context:SetBlendMode(Blend.Solid)
     end
  end
end

Maybe I'm doing something wrong?

March 10, 2015

You broke it!

March 9, 2015

For flowgraph Timer.zip

March 9, 2015

Indeed, thank you Rick. Update!

March 9, 2015

If anyone needs, I'll leave it here

Timer:

 if Timer~=nil then return end
 Timer={}

function Timer:Create(name, interval,enable)
 local timer={}
 timer.name = name
 timer.interval = interval
 timer.enable = enable
 timer.time = Time:GetCurrent()+timer.interval
 local k,v
 for k,v in pairs(Timer) do
   timer[k] = v
 end  
 return timer
end

function Timer:Update()
 if self.enable then
   if Time:GetCurrent() > self.time then
  self.time = Time:GetCurrent()+self.interval
  return true
   else
  return false
   end
 end
end

How to use:

function App:Start()
 --Timer
 self.time_hours = 0
 self.time_minutes = 0
 self.time_seconds= 0
 self.timer = Timer:Create("timer",1000,true)
end

function App:Loop()
 --Very complex calculation time 
 if self.timer:Update() then
   self.time_seconds= self.time_seconds+1
   if self.time_seconds== 60 then
  self.time_minutes = self.time_minutes+1
  if self.time_minutes == 60 then
    self.time_hours = self.time_hours+1
    self.time_minutes = 0
  end
   self.time_seconds= 0
   end
 end

 --Draw current time
 self.context:SetColor(1,1,1,1)
 --Seconds
 local seconds
 if self.time_seconds < 10 then
   seconds = "0"..self.time_seconds
 else
   seconds = self.time_seconds
 end
 --Minutes
 local minutes
 if self.time_minutes < 10 then
   minutes = "0"..self.time_minutes
 else
   minutes = self.time_minutes
 end
 --Hours
 local hours
 if self.time_hours < 10 then
   hours = "0"..self.time_hours
 else
   hours = self.time_hours
 end
 local time_string = hours..":"..minutes..":"..seconds
 self.context:DrawText("Timer: "..time_string,2,2)
end

You mean the framerate decreases by 5 FPS for each extra render? What is it originally?

Yes. The originally 30 fps. With one monitor 15 fps

March 8, 2015

There is a way to get the texture of the buffer, without a strong drawdown FPS?

Simple code of Monitor:

function Script:Start()
--Material
self.material = Material:Load("Materials/Monitor/monitor.mat")
self.entity:SetMaterial(self.material)

--Buffer
self.buffer = Buffer:Create(App.window:GetWidth(),App.window:GetHeight(),1,0);
self.buffer:SetColorTexture(Texture:Create(App.context:GetWidth(),App.context:GetHeight()))
self.buffer:Disable();
end

function Script:UpdateWorld()

self.buffer:Clear()
self.buffer:Enable()
self.entity:Hide()
--self.camera:Show()
App.world:Render()
--self.camera:Hide()
self.buffer:Disable()

self.material:SetTexture(self.buffer:GetColorTexture(),0)

Context:SetCurrent(App.context)
self.entity:Show()
end

One monitor, point light and room 4x4

As a result, the FPS - 5

If two monitor FPS - 10 etc

Implementation in irrlicht engine:

ITexture* RTTTex = driver->createRenderTargetTexture(dimension2d<s32>(512,512));

Result over 75 fps (For me)

Demo, Source code and shaders: irrlicht.zip

Thank you guys. Updated.

March 5, 2015

Thanks. No, texture took from the Internet. Pieces did imposition on the UW texture. (Google Translate )

(Спасибо. Нет, текстуру дерева брал из интернета. Затем частично, выборочно вырезал части и накладывал на текстуру UW. Затем, рисовал края.)
