I saw there is a Timeline Pause action which you need to specify a tag

But I dont seem to find where can I tag the whole Timeline?

The reason this isn't working is because the conditions that pick the Family object don't also pick the specific Factory object, so your "Factory isDestroyed" condition picks all of the Factory objects.

There are a few ways to get around this; the simplest is to shift your "isDestroyed" variable to the Family and then change all the conditions and actions referencing the Factory object to the Objects family.

Another way would be to move all the Factory conditions and actions to a function; then, in the ObjectType = "Factory" subevent, pass the picked Object's UID to the function in a parameter and use that passed UID in the function to pick the Factory.

Thanks, the UID method sounds good!

that would be a pretty complicated collision mask... but it should work.

an alternative would be to make simpler cloud shapes, and then combine several to make up a cloud that looks like that - an if you randomise it, you could get different clouds each time.

If I have multiple instance of the factory objects in my screen, how can I reference only the one that I touch in my actions?

I have a number of Factory object instances on my screen, when they are touched, animation will play on the touched instance.

But now when they are touched, all of the instances will play the animation.

How can I reference only the object that I touched?

The simplest method would be to use the is overlapping condition.

On touched factory

->cound is overlapping factory(inverted), do foo

Thanks, is the overlapping check determined by the bounding box of the sprite or the collision mask?

I found the problem, somehow the collision mask are not correctly set. So the clouds are getting a full rectangular collision box...

Combining with your solution it works perfectly now.

Thanks again for everyones help.

I have sprite obstacles in different shapes and sizes covering some other sprite objects in screen

For example clouds covering a factory, how can I implement some kind of click/ touch mask so that the touch to the factory is ignored when the white part of the cloud is touched?

what I do in similar situations is put all the objects in a family, and then when checking for touch, use the family and pick the top instance. Then if it is an obstacle, just ignore it.

Thanks. Can you show me an event sheet example of how to implement this?

If sprite1 not overlapping sprite2.

Or add a boolean variable to sprite1 and turn to false if is overlap the sprite2, then compare variable.

Thanks. If I have sprites that has irregular shapes? Can I detect the touch based on the collider?

I have a game object for user to touch and destroyed.

When it is cover by another obstacle, I want the obstacle to block the touch event, how can I implement this?

Thanks it works
