Hello World! I have this enemy that has an attacking animation of 2 images, when he is attacking I want it to stay as the first image for 49 steps, then move to image 1 for 1 step...

Here is my fail of a try in the end step event

var done;
    done = 0
    if done = 0 {alarm[2] = 49; done = 1}
    if event_perform(ev_alarm,2)
    {
        image_index = 1;
        image_speed = 1;
        alarm[3] = 1
    }
    if event_perform(ev_alarm,3)
    {
        image_index = 0;
        image_speed = 0;
        done = 0;
        alarm[2] = 49;
    }

But does not work How would I accomplish this? Thanks World!

I think you're confused about what event_perform is:

event_perform(type,numb) Performs event numb of the indicated type to the current instance.

Instead of using those 2 IFs, take that code and put it in their respective Alarm events (Alarm2 and Alarm3). Alternatively, you can try this in the Step event:

if image_index == 0
image_speed = 1/49

if image_index == 1
image_speed = 1

Also, you probably shouldn't use variables called "done". The code snippet in the forum shows them in bold, which might mean that they're used in the GML syntax.

Both those don't seem to work

It never changes to image 1 it just stays at image 0

I just tested my second method and it works. Make sure to also delete all your code from the End Step event.

[willowvayle]

Uh... I can't delete what is in the end step because I have stuff dealing with changing his sprites when he is moving and standing still as well :/ I tried putting the code in the begin step event but that did not work either...

[PetzI]

Then don't delete all of it, just the part that you posted.

[willowvayle]

Did not work...

Here is the code which your code is in...

if enemy_fighting = true
{
    image_speed = 0;
    switch (temp_dir)
    {
        case 1: sprite_index = LightDragonKnight_Fighting_Up;
            break;
        case 2: sprite_index = LightDragonKnight_Fighting_Left;
            break;
        case 3: sprite_index = LightDragonKnight_Fighting_Down;
            break;
        case 4: sprite_index = LightDragonKnight_Fighting_Right;
            break;
        default: break;
    }
    if image_index == 0
    image_speed = 1/49

    if image_index == 1
    image_speed = 1

}

EDIT: Changed the code like so...

if enemy_fighting = true
{
    if image_index == 0
    image_speed = 1/49

    if image_index == 1
    image_speed = 1
    switch (temp_dir)
    {
        case 1: sprite_index = LightDragonKnight_Fighting_Up;
            break;
        case 2: sprite_index = LightDragonKnight_Fighting_Left;
            break;
        case 3: sprite_index = LightDragonKnight_Fighting_Down;
            break;
        case 4: sprite_index = LightDragonKnight_Fighting_Right;
            break;
        default: break;
    }
}

And now the image is constantly moving


EDIT 2: Anyone? Anyone? Bueler?

When image_speed is a fractional number, image_index likely result in fractional like 0.9998967, so it rarely comes exactly equal to a whole number like 0 or 1.

if image_index == 0
    image_speed = 1/49

    if image_index == 1
    image_speed = 1

Try to change those conditions into inequalities.

if (image_index < 1) {
    image_speed = 1/49;
}
else {
    image_speed = 1;
}

[PetzI]

It doesn't matter if it comes out fractional, if it comes out as 0.9998967 GM rounds it and the IF test returns equal. I've tested it and it works fine, so the problem is something else in his code.

What exactly is happening when you say "it's constantly moving"? Also, you did delete the first code that you posted, right?

[willowvayle]

@torigara Well that did the trick thank you!

@PetzI When I said it was constantly moving I meant it was just doing the animation at a speed of 1, thanks you for your help as well
And yes I did delete the code I first posted
