lengthdir malformed with statement

[Coleson Frey]

i even used the code from the manual and it doesnt work
/// randomly shoot
can_shoot -= 1;
event_inherited();

xoffset = x + lengthdir_x(5, obj_rotTurret.image_angle)
yoffset = y + lengthdir_y(5, obj_rotTurret.image_angle)

//xoffset = x + cos(image_angle * pi / 180) * 5
//yoffset = y + sin(image_angle * pi / 180) * 5

if (can_shoot = 30) {
image_index = 2;
}
if (can_shoot = 100) {
image_index = 1;
}

if (can_shoot < 1) {
with instance_create(xoffset, yoffset, obj_turret_cannonball); {
direction = obj_rotTurret.pointdir;
speed = 4;
}
instance_create(xoffset, yoffset, obj_effect_explosion);
can_shoot = (irandom_range(120, 200))
image_index = 0;
}

with instance_create(xoffset, yoffset, obj_turret_cannonball); {
direction = obj_rotTurret.pointdir;
speed = 4;
}

The semi colon in that first line is your issue.

Can someone please tell me where today's rookies learn to clip off control structures with needless semicolons? This mistake is absurdly common nowadays, yet nobody made it back when I started. It's not in the Manual or any worthwhile written or video tutorials, so where does it come from?
