ok.
I have gone through many examples on inventory making, but I suck at understanding them.
All I need is help on understanding how to start one like a simple, click object and it appears in a box.
I'm really don't understand the examples I have gone through.
I just wanna learn how to make one! (please)
start me off and tell me how it is done!
if you like you can direct me to an example and I'll see if it is helping.

what does the "i" stand for?
or is it a variable?
what does "mod" mean?
also I have a lot to look into the draw event!
ps
I made a check "if show = 1" so I can press the I button to show or not show the inventory!

I didn't look at the code, so maybe this isn't accurate, but i is usually an arbitrary variable used in for loops which only takes value within said for loop. For example (assuming that such is the case):

for (i=0; i<10; i+=1)
{
//I can access the variable 'i' inside the for-loop
draw_text(x,y+(i*10),string(i));
}

//However, I cannot access that same 'i' variable outside the loop:
draw_text(x-10,y,string(i));

//Should return an error for the variable i was never created/defined/initialized

Also, the mod function, or modulo, in GameMaker (and a lot of other languages) --- divides integer a, by integer b and returns the remainder. So if I have:

var c;
c = 3 mod 4;

c will be assigned the value, 3, because 3 divided by 4 is 0 with a remainder of 3.

Thanks for the info on that for loop!
