I'm going to place a lot of actors to be "obstacle" in this game..
But i dont know how to place it randomly ?
I figured out if i place it manually then this game such a bored.. Then i need a randomly placing this obstacles..

You have to drag all the actors that you want on the scene, and inside every actor put a Change attribute: 'self.positionX' to 'random (min,max)' <-- lower and highest X values it can have.
And the same for the Y if desired.

thanks!!
but if i want it more than 1 in the scene, how to do that?
do i have to put the same actor a lot in a scene?

it depends of the kind of game you want to do.
If only a few are showing at the same time on the camera view, I'll try recycling the actors. This way, those who are off the view, can change his position to a new one (with 'Change attribute').
Obviously, you could use spawning, but the problem is that increases the RAM usage and the loading time.

If you explain the kind of game, I could be more precise

Hope it helps

Im going to make a game that the actor is running from top layer to the bottom layer and then there are a lot of obstacles that it has to avoid. the problem is the obstacle. how could it be randomize the number and location? I knew about the location problem because of you. The only one problem is the number of the obstacle. hmm..

Just have to make an attribute to control the number 'HowMany'.
Create an actor that will spawn the obstacles 'Generator', and drag it on the scene.
In this actor make a Change attribute 'HowMany' to random(min number of actors,max number of actors).
Inside this actor, also do the Spawning.And every time you spawn an obstacle Change att 'Howmany' to 'howmany-1'
You can make the Generator actor all screen tall and wide and make it invisible, and when the game starts the obstacles will appear in random locations and number.
I think this should work if the game isn't scrollable.

Hope it helps.

No no, don't do "You have to drag all the actors that you want on the scene, and inside every actor put a Change attribute". The energy/processing it takes to run is too huge to save all at once. I suggest an Actor called something like "spawner", and after you enter in a certain area, give the spawner an Boolean called "triggered".

Make a rule in the Spawner that says, if "triggered", Spawn Actor at X location (random[minimum distance far away],[maximum distance]. Use the expression Random and it will make take the first number and the second number and randomized between them. Like in the X in the Spawn Actor box, Random(20,40) and it will be between 20 X pixels to 40 X pixels away from the spawn.
