Creating and using an blocked Area for Constructions

RPGFabi · 11. März 2019

Hello Modding Collegues,

I've got a small Problem. For one of my new WIP-Mods i need a way to "block" an area. As all the positioning is totaly random i need to block the Area of an object, so the next object can't be build there. I tried to figure a way out to do this, but it seem to do not work. I've created some functions:

The Table for Blocked Areas looks like this.

Code

Blocked_Areas = {}

Every single Area is added with this.

Code

Blocked_Area[#Blocked_Area +1] = {low Y Pos, high Y Pos, low X Pos, high X Pos }

1. check if the blocked Area is free

Code

function RPGFabi_Gardencalculation.checkiffree(Blockierte_Flaeche, Pos_X, Pos_Y)
			local blocked = false


			for i = 0,#Blockierte_Flaeche do
				if
					((Pos_Y > Blockierte_Flaeche[i][1]) and (Pos_Y < Blockierte_Flaeche[i][2]))
				or	
					((Pos_X > Blockierte_Flaeche[i][4]) and (Pos_X < Blockierte_Flaeche[i][3]))
				then
					blocked = true


					break 
				else


				end
			end
			return blocked
		end

2. create an block from Center

Code

function RPGFabi_Gardencalculation.createblock(X_Pos, Y_Pos, Width_X, Width_Y, safety_width)
			local Table = {	
				Y_Pos - Width_Y/2 - safety_width,
				Y_Pos + Width_Y/2 + safety_width,
				X_Pos - Width_X/2 - safety_width,
				X_Pos + Width_X/2 + safety_width
			}
		end

Width is the Distance from the first end of the object to the last end of the object
safety width is the extra distance where nothing can be placed.

3. show blocked Areas
Place an Object at the side of every Block

Code

function RPGFabi_Gardencalculation.showblocked(Blocked_Areas, Y_Housepos)
			local Table = {}


					local skalierung = {
						x = 0.1,
						y = 0.1,
						z = 0.1
					}
					local rotation = {
						x = math.rad(0),
						y = math.rad(0),
						z = math.rad(0)		
					}


				for i = 1,#Blocked_Areas do 
					local X_Mid = Blocked_Areas[i][4] - Blocked_Areas[i][3]
					local Y_Mid = Blocked_Areas[i][2] - Blocked_Areas[i][1] 
					local Modelpfad = "asset/track_multi_gleisfeldleuchte_db_doppelt"
							local translation_A = {
								x = X_Mid,
								y = Blocked_Areas[i][2],
								z = 0
							}
							local translation_B = {
								x = X_Mid,
								y = Blocked_Areas[i][1],
								z = 0
							}
							local translation_C = {
								x = Blocked_Areas[i][4],
								y = Y_Mid,
								z = 0
							}
							local translation_D = {
								x = Blocked_Areas[i][3],
								y = Y_Mid,
								z = 0
							}
							local translation_E = {
								x = X_Mid,
								y = Y_Mid,
								z = 0
							}
							-- [[
							Table[#Table +1] = {
								id = Modelpfad..".mdl", 
								transf = transf.scaleRotZYXTransl(skalierung, rotation, translation_A)
							}
							Table[#Table +1] = {
								id = Modelpfad..".mdl", 
								transf = transf.scaleRotZYXTransl(skalierung, rotation, translation_B)
							}
							Table[#Table +1] = {
								id = Modelpfad..".mdl", 
								transf = transf.scaleRotZYXTransl(skalierung, rotation, translation_C)
							}
							Table[#Table +1] = {
								id = Modelpfad..".mdl", 
								transf = transf.scaleRotZYXTransl(skalierung, rotation, translation_D)
							}
						--	]]	
							--[[
							Table[#Table +1] = {
								id = Modelpfad..".mdl", 
								transf = transf.scaleRotZYXTransl(skalierung, rotation, translation_E)
							}
							]]
				end


			return Table
		end

4. Create the m and b variable of an straight line out of 4 coordinates

Code

function RPGFabi_Gardencalculation.getLine(Einfahrt_Y, Einfahrt_X, Haus_Y, Haus_X)


				local m = (Einfahrt_Y - Haus_Y) / (Einfahrt_X - Haus_X)			-- Steigung
				local b = Einfahrt_X - (m * Einfahrt_Y)							-- Offset


				local Table_Line = { m, b }
			return Table_Line
		end

5. Use the Lines (2 create an groundface) to create an blocked Area. This should use small slices of the Area to create better blocked Areas

Code

function RPGFabi_Gardencalculation.blockArea(Line_A, Line_B, EX, Haus_X, Y_Houseposition)		
			local Distance = 0.5									-- Scheibengröße
			local Amount = (EX - Haus_X) / Distance					-- Anzahl der Scheiben
			local Left_Y = 0
			local Right_Y = 0
			local Table_Block = { }


			-- erstelle Koordinaten für Scheibenweise Blockaden
				for i = 0,Amount do
					-- get low x
						local low_X = EX - (i * Distance)
					-- get high x
						local high_X = low_X - Distance


					-- get left Y
						local L_YA = (low_X - Line_A[2]) / Line_A[1]
						local L_YB = (high_X - Line_A[2]) / Line_A[1]
							if L_YA > L_YB then
								Left_Y = L_YB
							else
								Left_Y = L_YA
							end 
					-- get right Y
						local R_YA = (low_X - Line_B[2]) / Line_B[1]
						local R_YB = (high_X - Line_B[2]) / Line_B[1]
							if R_YA > L_YB then
								Right_Y = R_YB
							else
								Right_Y = R_YA
							end 
					-- Create Blocked Table
						Table_Block[#Table_Block +1] = { Left_Y, Right_Y, high_X, low_X }
				end
			return Table_Block
		end

Problem:

It doesn't show me the blocks correct. As I don't know if they are created correct or not, which I need to check soon, I thought Hey maybe someone else got an easier way.

Can someone help with the creation and use of an blocked Area Table?

The Beginning would be the Table groundfaces use:

Code

local Table = {
{X,Y},
{X,Y},
{X,Y},
{X,Y},
{X,Y},
{X,Y},
{X,Y},


}

I've got it

Now i Have a Script that can block an given Area (with 4 Points), block an Area from Center, check if an Position is free, show blocked and show not blocked Areas.

Of course the last 2 functions are only for development if everything works.

Right now I'm thinking about Creating an own Mod (Script, Model & Texture) with it so every Modder can just require this Mod to get this functions done.

What do you think about it?

This is how it looks like if you are in Testing mode.

Else it is invisible
