Spawn actors at random times without them eventually spawning at the same time

CraigMack

I am creating a car game where the main car (You) needs to avoid cars that are coming down the road, and to do this you need to switch lanes. The main problem I have is spawning in the Enemy cars that are coming down. I am wrapping Y

I used this timer that would spawn in the actors at random times but the actors eventually ended up spawning at the exact same time and i lost the game because i couldn't go to any free lane.

It would help if someone could help me with the code, and provide a spawner that would spawn cars at set positions at completely different times and they never spawn at the same time.

My demo is a bit more complicated than what you just posted, which has some basic errors (random values from 1 to 7 cannot equal 8; having a rule with All conditions selected instead of Any and conditions that can't be true at the same time means that the rule will never fire; etc.) but hopefully you find it useful.

Simple Apps

I think you can use only one actor to spawn enemies down.
and make the spawner to move left and right.
and spawn at random timings. i hope you understand.

Do you know how i would do that? and im not quite sure what you mean

I recommend not wrapping Y and just spawning cars randomly.

Simple Apps

make self attribute (start X )for the Spawner

1st rule:

change attribute (start X) to (self position x)

2nd rule:

interpolate

when self position x = self start x

interpolate self position x to selfstart x -200

3rd rule

interpolate

when self position x = self start x-200

interpolate self position x to selfstart x

Yes i understand what you mean but my game is kind of like the game on the app store 2 cars by ketchapp if you guys have it. I need to avoid the cars that spawn at the top of the screen by moving left or right but the problem i have with this is that all the cars i have set up to spawn eventually spawn at the same time and there is nothing i can do.

Simple Apps

You take two spawnners
one move left and right between 1 to 100
and another move left and right between 100 to 200
so that the enemies don't spawn at the same time

This is a picture of the sort of game i am trying to create. I understand what you are saying but i need the cars to come down the Y axis and the main actor just to stay in the same spot and move left and right

ive got the actor moving and the walls set up its just the enemy actor bit and the spawning which i am struggling with

You rejected my answer so I'm trying to understand what you need. Do you need the car actors to wrap? I've never played 2 Cars but it looks like the shapes don't actually wrap in that game:

What might help is to have a description of how you want the cars to spawn. For example, do you want only one (randomly chosen from four choices) car to spawn at a time? Or do you want up to four cars to spawn in four separate lanes? In the image you posted (http://prntscr.com/5pnyrd), it shows two cars spawning at the same time in different lanes. Is this okay?

Lastly, what actual rules have you tried so far for spawning?

CraigMack

As you can see in that video the shapes spawn in at the top and move down i am trying to do the same concept but with cars. My problem is ive searched on youtube and the forums and all of the spawning methods i have tried the cars eventually spawn at the exact same time (all cars spawn in a row) and the main character has nowhere to go apart from losing.

CraigMack

I want to spawn a car randomly from four or more choices so the player has more options on where to go

I see what you're saying. I have a demo that shows how to do this but you'll need to figure out how to modify it so that it's not always 3 of 4 cars.

This was the first behaviour i tried from looking at a youtube video but it was not what i was looking for

Yeah thanks

You asked about spawning 5 actors. To do so you would add two more spawn actor behaviors which would also require two more table rows. The random number in the demo chooses a row NOT to spawn. So currently, it chooses 1 of 4 rows but you could change that to 1 of 6 for example to spawn 5 of 6 possible positions.
