Would something like this work for you:

for each badguy

badguy.angle > x

badguy.angle < y

.. set animation to z

Repeat for each animation.

Remove all pick random conditions and add For Each zombie - condition after your every x seconds condition.

The idea is that whenever you randomize the direction, you do it for each zombie. The direction conditions just move the zombies with specified directions. :)

Also, instead of global variable (every zombie has the SAME direction) you should use instance variables. Give your zombie object 'Direction' variable and modify your every x seconds condition to set that instead of global variable.

Here is a demo that has similar situation:

Evil sprites demo

On collision trigger they are both picked, so you have to 'browse' through them using pick nth instance.

yess its working now.

Thank you so much.

But could you elaborate the logic of the population being reset to 0 every 1 second?

If you keep adding to it every second, you'll get your total population added to it once per second. That's why we need to set it 0 before 'refreshing' the value :)

In your every tick event you are setting direction to random, that would cause the spinning. Move that under the random condition. Also take out 'female_zombie_direction' conditions away from under that condition, and move them to the top level. You can remove the every tick condition all together. Might work. :)

EDIT: Also, rather than round/random use choose(0,1,2,3)

Variable TotalPopulation

Every 1 seconds

..Set TotalPopulation to 0

..For each Sprite

.. Sprite.owner = 1

... add Sprite.population to TotalPopulation

.. Set PopulationTextObject text to ("Population is " & TotalPoulation )

That will count every player owned sprites population together, was this what you were after?

Made few fixes:

Fixed project

Few notes: You could use containers and families to simplify your project a lot, just by using those you could have 75% less events with 100% of the functionality and 200% more manageability! :)

i did the global variables, but i can't seem to get it right. I can't understand much from the links. Is it okay for you to explain in more detail?

Thank you very much :)

At the event '-> On drag start' you'll need to set those global variables to position of your object:

DragStartX=Object.x

DragStartY=Object.y.

Then on event '->dragNDrop dropped':

if(not overlapping TargetObject)

.. set object.x to DragStartX

.. set object.y to dragstartY

Check this thread for some discussion about that topic. It's not really a problem, you should aim to make your events as easy to manage and understand as possible rather than doing them with as little characters /rows as possible. Most performance hit will come from a) visualization b) inefficient events. 60 events for movement does sound a bit steep, but I don't know how complex your movement system is :)

You can find more info on performance here.

Don't think editing families runtime is possible.

I'll take a look into triggers, but I should point out that I'm aware that the code above isn't the best approach. I'm using this approach because I need to store the newly created object, then work with it in a new top-level event which is a C2 issue.

I'd still recommend you use 'on created' trigger, no need to save UID's or other stuff anywhere. It's a very coderish approach. :)

You could so something like in this example:

Evil sprites example

There are lots of ways to do it, this is a simple approach where you define the spawn range from the middle of the layout (scrollX, scrollY).
