syntax for c# to do this math.

function checkCollision(a, b)
    --With locals it's common usage to use underscores instead of camelCasing
    local a_left = a.x
    local a_right = a.x + a.width
    local a_top = a.y
    local a_bottom = a.y + a.height

    local b_left = b.x
    local b_right = b.x + b.width
    local b_top = b.y
    local b_bottom = b.y + b.height

    --Directly return this boolean value without using if-statement
    return  a_right > b_left
        and a_left < b_right
        and a_bottom > b_top
        and a_top < b_bottom
end

Im trying to do this in c#, but I dont know what the syntax for it is right now what i got is

c#
 static int DetectCollision(Object a,Object b)
    {
        private int a_left = a.x;

    }

c#
 static int DetectCollision(Object a,Object b)
    {
        private int a_left = a.x;

    }

Edited

Comments use // in c# (though /**/ for multilines). Give a and b type declarations. Make the method return type a bool, as it uses logic operator. The logic operator for and is &&. I assume “object” in your example code is a placeholder name. You should make it an actual rectangle class/struct, though I assume that is what you mean’t

thanks be to GOD random person, i thought it was returning int, but i didnt read the comments haha object is for things like player object in my code im gonna check collision between two objects for the method im gonna be using

m!ke•4mo ago

Did you name a class “Object”?

HouseAdmin•4mo ago

m!ke•4mo ago

Ah okay. Then you’re good

HouseAdmin•4mo ago

it gives the error

ColiisionRelated.DetectCollision(object, object)': not all code paths return a value

ColiisionRelated.DetectCollision(object, object)': not all code paths return a value

c#
    static bool DetectCollision(Object a,Object b)
    {
        private int a_left = a.x;

    }

c#
    static bool DetectCollision(Object a,Object b)
    {
        private int a_left = a.x;

    }

for this

Also, access modifiers cannot be used within methods. Simply do: int myInt = 0; Well, you gotta complete the pseudo code

thanks be to GOD person yeah i was guessing that too but i wasnt sure well thanks be to GOD random person for helping me i will closethe thread now

m!ke•4mo ago

No worries. Glad I could help. :)

Also, chances are you don't want to use Object but rather a concrete type

HouseAdmin•4mo ago

I thought thats what objects do? i mean are you make objects out of classes using new

Angius•4mo ago

Well, yes You make a class And you instantiate it And wherever is supposed to use that instance, uses that class as the type What you have here is the System.Object type, though, which is basically an any type Unless... you made your own class that's named Object, in which case I'd probably reconsider that name
