So I want my door to open whenever it collides with the player, assuming he has at least one key. And then one key gets subtracted from the total.
However, if he doesn't have any keys, he cannot pass through it.

if global.keys > 0 
{
oDoor.solid = false;
sound_play(door_open);
instance_destroy();
}
else
{
global.keys = 0
oDoor.solid = true;
}

Except when I hit the door first, and THEN grab the key, then try again, it doesn't work. But if I get the key first, then it opens.
How do I fix this?

if global.keys >= 1
{
oDoor.solid = false;
sound_play(door_open);
instance_destroy();
}
else
{
global.keys = oDoor.solid = true;
global.keys -= 1;
}

I think that should probably do it.

Nope, he just passes through it both times. With and without the key.

Hmmm okay, lemme think. So if he doesn't have a key, and then you go and grab the key, the door won't open. Do you have something that says when you pick up the key that global.keys += 1?

if global.keys >=1
{
oDoor.solid = false;
sound_play(door_open);
instance_destroy();
global.keys -= 1;
}
else if global.keys <= 0
{
oDoor.solid = true;
}


in the game start event set global.keys = 0;

Nope, if I touch the door, get the key and then touch the door again, it doesn't open.

The object is in the door object.

so if you touch a door, if your keys is more than 0, the door dies, and if you have 0 keys, then nothing happens?
If so why do you set its solid Boolean to false then destroy the door?

I solved it!

I had to put

oDoorDouble.solid = true;

in the creation event

and

if global.keys >=1
{
oDoorDouble.solid = false;
}
else if global.keys <= 0
{
global.keys = 0;
}

in the Step event.

[sneaky666]

why do you need this part
else if global.keys <= 0
{
global.keys = 0;
}
?
will global.keys ever be less than 0?
