You can set the state for the green ball as you have done and also set the state for the red ball to show that it is in use, here fixed : dropbox.com/s/vs9e45pjj8v72d1/Ball%20Shooter.c3p

— Thank you for your quick fix, you really saved me! All this instance thing goes over my head. Thank you again so much! ^_^

You could use the boolean instance variable to turn on 1 green ball only.

Then you can do the event with the green ball which boolean is true.

Thank you for your reply. But sorry, I have tried with instance variables but couldn't get any decent comparison to make that will particularly differentiate only 1 green Ball at a time. Trying with instance variable either makes the Redball stop rotating or all the green Ball stick to the Redball. I know I must be making some silly mistake as I am new to Construct & it would be really helpful if you can give a clear explanation on how can I use the instance variable properly. :)

In this project when the Redball is in action with the green Ball & if another instance of the green Ball comes near the Redball, the green Ball also stops. I am trying to work one green ball once at a time, that means when the Redball is positioning the angle of one green Ball all other instance of green Ball will ignore the events. If anyone can give me any hints that will be lifesaving! :)

control: When the green Ball is near Redball leftclick mouse to control the angle of green Ball & release mouse button to shoot in opposite direction.

Well after some researching I came up with this process.

In this capx one problem I am facing is, between the newly created tilemap & the previous tilemap there remains a small gap. How can I position these tilemaps so that there is no gap between them? Any help is appreciated. :)

Hi I have already seen the example of auto runner given in C2, but one problem is that the platform used in the example is a tiled background block. So what I am trying to do is, instead of tiled bg I want to use tilemap so that I can change the block animations overtime from the tileset (e.g: edges of the road to a edge animation). I hope I made my point clear.

I am new to C2 & searching for hours in forums & clicking here & there but nothing getting into my head. :( If any noble soul can just give me a hint of what to do, may be my mind can get a restart.
