For the record, that's still valid as of GMS2

So you told me.

I'm so glad Game Maker is still the garbage we know and love 

[Saniblues]

Which smiley do I use to express a deep feeling of concern

[MedO]

Wait what? Unary plus works as abs?

[Saniblues]

I should've conveyed this a bit better.

Also, no. Unary plus doesn't appear to do anything.

Aaah, das macht so viel mehr Sinn, hatte die Reihenfolge vertauscht.

[Phantom Brave]

for({(x) = (0)};false;{(x) = (y)}){}

Nothing else needs to be said.

for({{{{{{{{((((((((x)))))))) = y; {y += 1}}}}}}}}}; false; {}){}

i = 0;
x = 5;
for({{{{{{{{{var i; i = 10}((((((((x)))))))) = i;}}}}}}}}; false; {}){}
show_message(x)

shows 10

[Phantom Brave]

for({ var i; i = 0 if(i := 0) i = 1 with(100001) begin (100001).y = 10; instance_destroy()} ; end; false; i = 0){}

deep hyperventilation

[Phantom Brave]

x = script4
(y) = 1234
show_message(x)


The value of the identifier "script4" is 4. It's the id of a script that returns 1234. This code shows 1. Adding a semicolon after script4 makes it show 4. So does deleting the second line.

[Phantom Brave]

(id) = 0 // can't assign to the variable (id is a read-only variable)
(100001) = 0 // variable name expected (it wants (100001).x or something)

id is equal to 100001 here and lvalues inside of parens are okay

[Phantom Brave]

var i
(i) = 0


Unknown function or script: i


it sees:

var;
i(i) = 0

[Phantom Brave]

var script0(0)

it sees

var;
script0(0)

[Phantom Brave]

id, id[0], and id[n] are identical

numbers are rounded before being used as an array index (1.5 rounds up to 2, 1.25 rounds down to 1)

[Phantom Brave]

the bbox_PLACE variables are always rounded, even if the coordinates are not

[Phantom Brave]

test post please ignore

I just found an, uh, serious problem in Game Maker 8.0.

Create event of object0:

Code: [Select]

time = current_time;
for(i = 0; i < 10000; i += 1)
{
    t = instance_create(0, 0, object1);
    t.temp = script0(t);
    if(instance_exists(t))
        with(t) instance_destroy();
}
endtime = current_time;
show_message(current_time - time);
time = current_time;
for(i = 0; i < 100000; i += 1)
{
    t = instance_create(0, 0, object1);
    t.temp = script0(t);
    if(instance_exists(t))
        with(t) instance_destroy();
}
endtime = current_time;
show_message(current_time - time);

script0:

Code: [Select]

with(argument0) instance_destroy();
return 1;

First loop: no errors, nothing bad at all, finishes in less than a second.

Second loop: Finishes in 139777 milliseconds.

Basically, somehow, variables can be modified after their associated object is dead as long as their lvalue is referenced before the object is destroyed.
