It'd be great if you do, A documentation would come handy for those who have no clue on what they're doing, like me LOL thank you

DotNet / Re: How do I use pollEvent Method with C#

May you please give some more detailed information on how to do it? I started with sfml soon so I barely understand, and with no documentation, things come to be very difficult

DotNet / How do I use pollEvent Method with C#

« on: April 24, 2020, 06:41:00 am »

I'm trying to convert this

while (app.isOpen())
    {
        Event e;
        while (app.pollEvent(e))
        {
            if (e.type == Event::Closed)
                app.close();
        }

From C++ to C#, However, When I'm trying to do the pollevent part I dont see such method, and this is basically the heart of the game I'm making, may someone please tell me what would be a proper way to translate this into C#

Do you know where can I find the SMFL Documentation for C#?

Hello everyone, I'm trying to translate the cars game from the "Lets make 16 games in c++" video, form c++ to c# since I'm trying to learn how to and get familiarized with it, however, I've encountered a major problem and it is, My console is saying that  "Program.Car.move() is not accessible due to protection level", however I already made sure that everything is public so I don't know what really is going on here, I'd like to get some help with that and also with the last part of the code which is saying that "you cant convert the type 'double' to 'int' (check if you're missing a conversion)" or something like that /*Sorry I'm using VS in Spanish*/

I'd be really thankful if someone could tell me what's going on asap, friendly reminder, this is my first time using SFML in general and I knew c++ as well as c# so I'm trying to translate it, if something is wrong please point it out too so I can fix it or at least try to! thank you all
