Can we show changing texts in the windows?

[coarse owl]

you can use CheckCollisionCircleRec to determine when the ball hits the paddle

[coarse owl]

I cannot compile this because pong.h is missing

[coarse owl]

here's the rest of the files

[coarse owl]

okay i will see

thks

how can i use vectors? Cause that means i would have or change everything

this functions needs a vector and a rectangle variables

and also how do i use rectangles ?

[coarse owl]

Do you understand using a struct?

yeah i know about structs

[coarse owl]

Then you should understand the Vector2

It is two floats, x and y

oh okay

sounds simple on paper

It shouldn't need explanation beyond that

Have you opened raylib.h?

the file itself ?

Yeah

nah i'm just using it in this project

i haven't opened it

Well you should

It's documentation

lemme check that then

thanks

Can we show changing texts in the windows?

Okay so i have a question. Now that my program is working, i made a score system. But all the draw text functions have const char*. Isn't there a way to show the score that is changing

TextFormat("score: %d", score)

or sprintf

oh okay

thks again i guess

[coarse owl]

don't store the pointer this function returns btw

oh its about pointers? i will read it in the raylib.h

[coarse owl]

what do you think a const char* is?

[coarse owl]

yeah i know about "constant" char 😆 thanks

char* <- this is a pointer type

you know that, right?

wait you cannot change the value of a const char with a pointer, can you ?

i know its a pointer but the const char cant be change.

you can change the value of the pointer but you can't write anything through the pointer

ohh thats broken

const is kind of useless tbh

yeah 🤣

it doesn't help that you can cast the const away and write to it anyway

if you wanted both then that would be const char* const

this is "a pointer that can't be reassigned and can't be written through"

so by using a pointer you can change the value of the const char without passing the char itself

No

C has a (crappy) string convention of null-terminated string

you should read about it

i didn't know about it damn

the pointer is pointing to some memory, that contains an "array of chars", ending with a 0 byte

so you dont really change the const char then ? only the pointer

no that's just how you pass a string
it's const to indicate to programmers that it doesn't modify the "chars" the string is pointing to, it just draws the string

https://beej.us/guide/bgc/html/split/strings.html#strings

read this
(it's important, and basic)

yeah thanks because i didn't know anything about this

I try to avoid the standard C "pointer to null terminated char array" when I can
This isn't one of those cases

okay i will try on a small file to see if i understand

You can certainly just pass char* to these functions. That const is function internal thing effectively.

[sterile coral]

    const char* dog = "Dog"; // Pointer to constant char
    const char* cat = "Cat";
    char* const horse = "Horse"; // Constant pointer to char
    const char* const sheep = "Sheep"; // Constant pointer to constant char
    char* cow = "Cow";
    // These are valid.
    cat = dog;
    cow = horse;
    dog = (char*)sheep;
    // And you can draw them all.
    DrawText( cat, 20, 20, 20, RED );
    DrawText( cow, 20, 50, 20, RED );
    DrawText( dog, 20, 80, 20, RED );

[coarse owl]

Thks i already resolved the problem. I used a const char pointer and i changed it with the TextForm function

I don't remember exactly, you can go check out my github nblstrue
