Ok, i see what you mean.

Thank you.

I have some questions :

Is it possible to pick an instance by boolean instance and if it's possible, how to do it?

Where can i find a tutorial about picking instance by instance variable?

I thought I already said how to pick by boolean?

"object is boolean instance variable set" - condition..

For other instance variables it would be

"object compare instance variable" - condition

Construct doesn't work with vectors..

All images are exported as png..

using the svg (real vectors) or canvas (pixels) plugins are your only option if using vectors will improve your game..

The only real benefit of vector-graphics is the scaling, but the scaling methods used on bitmaps inside Construct2 have always served me well..

If you destroy on collision only the family member colliding will be destroyed, for it is picked in the event and the others aren't..

And again, my above events are still the ones to use, just replace sprite with family..

Sprite on collision with player

sprite destroy

would only destroy the instance of the sprite that collides with the player..

If you really want to check the boolean it would be:

Sprite on collision with player

sprite is boolean

sprite destroy

Why not just use the sprite condition - is boolean instead of system compare?

It work's, but the tiny circle stays right where it fell and bumped over and over again to the same place. It also didn't follows the bigger one rotation flows.

Like I said, it's basic, but it works..

I found another example I downloaded and improved which does use pin and the bullet behaviour instead of platform..

Like you see, there are many ways to implement something like this..

It doesn't take many events either, but you'll always have to adjust it to fit your needs..

I'm sure I had a better example somewhere, but this is a basic implementation:

To recreate ROTO you wouldn't need any pinning would you?

To me it seems using platform behaviour and setting the angle of gravity towards the closest "planet"would suffice..

I was just about to ask this question, good that I searched for it first. Understand now that this is not possible either. Encountered too many of those now.

Construct is an awesome piece of software but too many things you can't do in it drags it down a bit unfortunately.

I'm not sure what you mean by Construct2 can't do it?

There's at least two options: animation frames or webgl effects..

Depending on the platform you want to export to you'd have to choose the right one..

When playing preview from the capx, I have no issues at all

The exported project does nothing however, are you sure they are exactly the same?

Feels to me like in the exported project the event is "on touched" while in the capx it is "is touching"

Without seeing your events and/or the capx, answering your question will be near impossible..

It might be me, but the ball never rolls up the hill or do you mean the little ramp?

I don't see anything wrong or unexpected in your capx..

It rolls down the hill, up the ramp an falls..
