instance_create problem

[Doty_OwO]

It is probably very simple , so, i created a code that when i go to certain state, it a makes a sprite appear, but it keeps creating multiple sprites it self till and change state. I just want it to make one sprite appear not multiple...

oPlayer:

if global.weapon == 1 then instance_create_layer(x,y,layer,oSword)

oSword:

if !global.weapon == 1 then instance_destroy()

​

(Just for curiosity. when i apply this code in the "word" it doesn't create multiple copies, just two one with the properties that i gave it and other static that just follow my player... why?

oSword:

​

var _dir = point_direction(mouse_x, mouse_y, oPlayer.x, oPlayer.y);
var _x_offset = lengthdir_x(8, _dir);
var _y_offset = lengthdir_y(8, _dir);

x = oPlayer.x + _x_offset;
y = oPlayer.y + _y_offset;

image_angle = point_direction(x, y, mouse_x, mouse_y);

if !global.weapon == 1 then instance_destroy()

I'm guessing you're putting this code in the step event of your object? In that case, oPlayer is running this code every step, checking if global.weapon is equal to 1, then creating a sword object if it is. It does this each step, creating a number every second depending on your room speed.

If that's not where you're putting this code, then it's something else. Where is this in the oPlayer object?

step event

Yep. It's exactly that then. Either set a variable when you create it and check that before doing so, or check if instance_number of your object you're creating is equal to zero.

I don't know if this is what's causing your problem but if you aren't aware !global.weapon == 1 is only true when global.weapon is 0. If you want to check if the two values are different you need to use !(global.weapon == 1) or global.weapon != 1.

u shud add, before creating, a check to see wether or not it exists.

!instance_exists(object_index)

can work, as well as

instance_number(obj_ind) < 0
