Hot bar Spell cooldowns

I only provided the code I'm using for the spell cooldown. here are 4 examples of what it looks like

if this is not enough information I will gladly provide more. again sorry for my horrible programming skills lol, thank you for any help

It seems that you do need some organization. If its me, I have some object that is tracking the spells and their cooldowns. This is independent from the cooldowns you are showing in the bar. This object would store the spells' cooldowns both in seconds, and as a percentage. Then, each box in the hotbar would know what spell it is currently referring to, and store some reference to it in a variable(this reference would lead back to the other object's list of spells). You want the spells to manage themselves, and the hotbar to ONLY worry about drawing whatever cooldown of whatever spell it is looking at(I assume you might have different spells in the boxes at any given time based on player preference).

Basically, each object should only be responsible for one basic thing. The object with the spells tracks its cooldown, and the GUI things only gets a reference to that and draws itself.

Another thought, I would try to reduce any code duplication where I can. Instead of having all those variables, either have multiple objects(one for each section of a bar), or have an array. This would let you set a variable for looping through the array if that's how you did it. Or if you have separate objects/instances, then each one would have an instance variable that tells it what keyboard key to check(and what spell it is referring to for the cooldown, and the rest of the code would be the same for all of them.

A simple example of this is with simple GUI buttons. All the buttons can use the same parent object. That parent object handles drawing text from a variable, and executing some function(also in a variable), and handles the animation/sound of hovering the cursor over the button. Then, you can put multiple of those in the room, and just override that variable either in the instance_create event or using the dialogs for editing instances in the room editor. Since the code that is drawing the text uses a variable, it never changes because you just change the variable. The same is said for the function to execute when the button is clicked.

If you think in the same fashion for all these hotbar buttons, you will see how you can get rid of all that duplicate code and just use variables to tell them what spells to refer to and what keys to check. If your spells can be executed from multiple places(either multiple buttons on a customizeable hotbar, or maybe a direct keyboard shortcut, or in a dialog showing skills like in some MMOs), then you want only one object that is actually handling the spell execution, and anything else that could make the spell execute would just tell that object to do it.

so I was able to simplify some code but still I cant get it to work as the original, any tips?
code:

create event:

GML:

spell_cell_size32x32 = 32;
spell_slot_width = 5;
slots_x = 4;
slots_y =22;
spell_sacle =1;
Spell_List32x32 = spr_test_magic_spellList;
spell_spr_items_colums =sprite_get_width(Spell_List32x32)/spell_cell_size32x32;

spell_slot_cooldown = 0;
spell_slots = 0;
ssc = 0;
HotBar_slots = 5;

ds_HotBar = ds_grid_create(2,HotBar_slots);

ds_HotBar[# 0,0] = Spell.W_strike;
ds_HotBar[# 1,0] = 1;

ds_HotBar[# 0,1] = Spell.A_strike;
ds_HotBar[# 1,1] = 1;

ds_HotBar[# 0,3] = Spell.F_strike;
ds_HotBar[# 1,3] = 1;

step event:

GML:

if spell_slots > 0{
if (ssc <= 0){ssc = spell_slot_cooldown;}
if (ssc < spell_slot_cooldown){ssc -= .05;}}

Draw GUI event:

GML:

var ii, ix, iy, xx, yy, sx, sy, iitem, spell_grid;
ii = 0; ix = 0; iy = 0;
spell_grid = ds_HotBar;

repeat(HotBar_slots){
xx = (slots_x + ((spell_cell_size32x32)*ix*spell_sacle))+430;
yy = (slots_y + ((spell_cell_size32x32)*iy*spell_sacle))+615;

iitem = spell_grid[# 0,ii];

sx = (iitem mod spell_spr_items_colums)*spell_cell_size32x32;
sy = (iitem div spell_spr_items_colums)*spell_cell_size32x32;

draw_sprite_part_ext(Spell_List32x32, 1, sx,sy,spell_cell_size32x32,spell_cell_size32x32,xx,yy,spell_sacle,spell_sacle,c_white,1); //draws the spell

/////////////////////cooldown code:
var spell_cd = obj_magicTree_GUI.ds_spell_info; //a ds_list containing the info of the spells, like name, and cooldown time.

spell_slots = ds_HotBar[# 0,ii]; // a ds_list of the hotbar containing the info of which spell is in which hotbar slot.
spell_slot_cooldown = spell_cd[# 2,spell_slots];
if spell_slots > 0{ssc = spell_slot_cooldown;} ///////when removing this code<<<<<<<<<<

if keyboard_check_pressed(ord(ii+1))
{
    if spell_slots > 0{ssc = spell_slot_cooldown;}

if spell_slots > 0{
spell_slot_cooldown = spell_cd[# 2,spell_slots];
ssc -= .05;}}

if spell_slots > 0{ //if slot is empty
draw_text_color(xx,yy,round(ssc),c_white,c_aqua,OutlineColor,OutlineColor,1); //Draws the cooldown
}
/////////////////////
ii +=1;
ix = ii mod spell_slot_width;
iy = ii div spell_slot_width;
}

when removing the code: if spell_slots > 0{ssc = spell_slot_cooldown;} from the draw GUI event, the cooldown start to count down but it counts down on all the slots.
Examples:

when I don't remove the code above, it shows the cooldown number but doesn't count down. because of that code.

any ideas would be apricated, thank you.

The reason it counts down all of them is because the only place you change ssc is when you press a number button

GML:

if keyboard_check_pressed(ord(ii+1))
{
    if spell_slots > 0{ssc = spell_slot_cooldown;}

so it will start to count down that skill

GML:

draw_text_color(xx,yy,round(ssc),c_white,c_aqua,OutlineColor,OutlineColor,1); //Draws the cooldown

and draw that variable for all the skills

But .. you are never really counting down the value in the obj_magicTree_GUI.ds_spell_info list, only reading it once .. your step event never changes it either, or does it just hold the value what to set the cooldown to?

So here, I edited the code between the ///'s .. you can remove your step event .. or actually do a cooldown loop there instead of the step event

GML:

/////////////////////cooldown code:
var spell_cd = obj_magicTree_GUI.ds_spell_info; //a ds_list containing the info of the spells, like name, and cooldown time.

spell_slots = ds_HotBar[# 0,ii]; // a ds_list of the hotbar containing the info of which spell is in which hotbar slot.
ssc = spell_cd[# 2,spell_slots];

if spell_slots > 0{ //if slot isn't empty

    // do some cooldown
    ssc -= 0.5;
       
    // this is where you are supposed to select/use the skill, right?
    if keyboard_check_pressed(ord(ii+1))
    && ssc <=  0{
        // use skill
        ssc = spell_cd[# ???,spell_slots]; // 2 is cooldown progress, which one tells what to set it to on use?
       
    }
   
    // the above code does change ssc .. but that won't affect your grid at all .. so we have to update it
    spell_cd[# 2,spell_slots] = ssc;
   
    draw_text_color(xx,yy,round(ssc),c_white,c_aqua,OutlineColor,OutlineColor,1); //Draws the cooldown
}
/////////////////////

I usually put the current cooldown in my hotbar grid, as only the equipped ones would need cooldown .. what is the 1 position for here: ds_HotBar[# 1, ?

now, if you put your cooldown in the hotbar, then you could use the ds_grid function to lower the value of the whole row/column at once .. and just make sure that when you draw it then you draw max(0,round(ssc))

so I took your code and tweaked it a bit, but ended up working. thank you for your help
Code:

Draw GUI event:

GML:

spell_slots = ds_HotBar[# 0,ii]; // a ds_list  containing the info of which spell is in which hotbar slot.
ssc = spell_cd[# 2,spell_slots];
spell_slot_cooldown = spell_cd[# 3,spell_slots]; //added  spell_cd[# 3 same as spell_cd[# 2 but wont change when cooldown.

if spell_slots > 0{ //if slot isn't empty

    // do some cooldown, stop it at 0
if (ssc <= 0){ssc = spell_slot_cooldown;} //if cooldown is at 0, rest to spell_slot_cooldown
if (ssc < spell_slot_cooldown){ssc -= .05;} //cooldown


    if keyboard_check_pressed(ord(ii+1))
        {
         ssc -= 0.5;   
        }
    
    // the above code does change ssc .. but that won't affect your grid at all .. so we have to update it
    spell_cd[# 2,spell_slots] = ssc;
  
    if (ssc < spell_slot_cooldown){ //only show when its on cooldown
    draw_text_color(xx,yy,round(ssc),c_white,c_aqua,OutlineColor,OutlineColor,1); //Draws the cooldown
    }

}
