A Random Idea

Is it possible to program a rotmg pserver with pascal (yeah, I mean the late 1900s language)? I just want know. I tried making a warrior that shoots while attacking, but it turned out pretty badly, cus the command that I use to draw pictures is so slow. Also, I can't make an enemy attack me while I am attacking. I know it has something to do with multi-threading (at least that's what my friend told me). If it is possible to do that in pascal, I'm creating another source (no joke).

Pascal is not the best choice for making a game. You will get so many bygs and issues if you're going with pascal. I don't see why you'd do that, and you will most likely not succeed. Make rotmg in java, or even just stick with c#. However you could remake the game in an engine elike Unity. There's also OpenGL/AL which is c#
