我需要批量协助if和组合变量

Question

我正在批量制作地牢爬行引擎。我制作了一个易于使用的地图编辑器，但需要特定IF语句的帮助。

(...) 
set Xpos=3 
set Ypos=3 
set unipos=%Xpos%.%Ypos% 
goto map2.2 

:map2.2 
rem  N 
rem ??=?? 
rem ==+== 
rem W =?=?= E 
rem ==+== 
rem ??=?? 
rem  S 
set donjon=2.2 
set tile1.1=x 
set tile1.2=x 
set tile1.3=ns 
set tile1.4=x 
set tile1.5=x 
set tile2.1=se 
set tile2.2=ew 
set tile2.3=nsew 
set tile2.4=ew 
set tile2.5=sw 
set tile3.1=nsw 
set tile3.2=x 
set tile3.3=nsew 
set tile3.4=x 
set tile3.5=nse 
set tile4.1=ne 
set tile4.2=ew 
set tile4.3=nsew 
set tile4.4=ew 
set tile4.5=nw 
set tile5.1=x 
set tile5.2=x 
set tile5.3=ns 
set tile5.4=x 
set tile5.5=x 
goto inroom 

:inroom 
set tile=tile 
set roomcheck=%tile%%unipos% 
set retire=inroom 
cls 
echo [%name1%] HP: %hp1%/%xhp1% 
if 1==%friend2% echo [%name2%] HP: %hp2%/%xhp2% 
if 1==%friend3% echo [%name3%] HP: %hp3%/%xhp3% 
echo ================================================== 
echo. 
echo You are now at room %unipos%. %roomcheck% 
if nsew==%roomcheck% echo There are exits in all four directions. 
echo. 

载入地图时出来的东西是这样的：

[您的名字] HP：300/300

您现在的位置room3.3。 tile3.3

我需要知道在标题内存在另一个变量时如何搜索变量！我可能说错了，但“％tile %% unipos％”是我能想到的最好的。它是一个...占位符，如果你愿意的话。

需要delayed expansion：

@echo off 
setlocal enabledelayedexpansion 

set "tile3.3=nsew" 
set "unipos=3.3" 
set "roomcheck=!tile%unipos%!" 
echo %roomcheck%
