I think a suitable DSL is also important, no one like using plain c++ to design..
⚛ Hz
The DSL should have data binding and style ability

Anybody know how to remove autolike from Facebook

It's not a question to be asked here

But it's very urgent

Pls help me if anybody have idea about it

Hello!

For example, Android use XML to layout,and Data binding is a plug-in

Guys, I'm sorry for break the conversation, but... There are a telegram group for game development in C++?

Oh, I was looking for that but i did not find nothing, I am a newbie game developer (but I am not a so newbie developer), and I want to find more C++ game developers to make a channel or group to share resources like architectures, tests, documentation and so on.

Guys, if I have a struct like "Position" and it has an int X and an int Y, and I have also another struct like "Acceleration" and it also has an int X and Y, it is ok to create two structs with the same items or just create one struct? There are a way and it is ok to create just one struct with n names?
Mat
Welcome :)

probably best to post a code example
Mat
It's not the name that identifies a struct

The name of struct is only for human...for reading and debugging

Yes, it is, but i want to keep my code readable.

So you should use different struct for different purpose

So you should use different struct for different purpose
Oh, well, I understand, so I will do that.

Something like "Physic_Component" is okey?
⚛ Hz
3 structs:physic_component, position, acceleration
⚛ Hz
And you can use nested struct declaration, if need
⚛ Hz
It will provider more readable and shorter code :)

Oh, sorry bro, i don't understand, do you mean that I should use 3 structs or just 1 struct that has all about these structs (that are the same)?
⚛ Hz
See this pattern

Oh, thank you bro!
⚛ Hz
Tip: you may not need to use the pointer to struct, you can just use nested struct declaration without "*"
Anonymous
Well bro. I catch it! 😁
Mat
Why do you need 3 structs for two variables?
Anonymous
Because each entity in my environment has an acceleration in the X axis and in the Y axis, same for the position, the entity has a position in the X axis and the Y axis.
⚛ Hz
For readable ,Object.position.x and Object.acceleration.x better than Object.x and Object.ax
Mat
So is the same structure
Mat
It's C or C++?
Mat
Structures or objects?

C++

I am using structures because i do not need that these values to have a behaviour.
Anonymous
Structures.
⚛ Hz
If you want to modify one's struct like add metadata to position..
Mat
So they're just the same :/
Enrico
Hi!
⚛ Hz
They are not for same purpose, although they have same structure...
Mat
I think is a waste, but it's just my opinion :)
⚛ Hz
Yes, it seems like OOP vs FP
Anonymous
But i will use OOP because i am making a entity object, and that object (almost obviously) has a behaviour.
Anonymous
I do not know what to do.
Mat
Objects =/= Structures
Mat
Structures are just a bunch of variables together, an object has a behavior
⚛ Hz
struct is same as class except the default visibility policy in C++..I used it to avoid the annoying public keyword, the public properties are also represented the behavior of a class. position and acceleration may have some same behavior so they can extends the Vector2D
⚛ Hz
So we have 4 classes now
Mat
You can give functions to a struct in C++?
⚛ Hz
Yes
Mat
Oh, so my point is invalid
David
But conceptually, I think it's better to use structs for a group of data, and classes for adding some behaviour
⚛ Hz
Yes, for readability
⚛ Hz
Nested class

Mat
So little difference, but not an unimportant one
Mat
I'm learning right now
Mat
So it's only a matter of how you'll access the variables and functions inside
