Using the "Button set invisible" action?

Actually if you want the button invisible on start you could choose to set it invisible in it's properties and only set it visible when needed, or create the button object when needed using a system create action.

I'm not sure why you would want to use an external script for that..

I'm not sure why that is, but I always use the ViewportLeft(), ViewportRight(), ViewportTop() and ViewportBottom() expressions

So instead of Window width/2

I use

0,5*(ViewportRight(0)-ViewportLeft(0))

Every x seconds counts from the moment you start your program..

What you describe above is consistent with that..

Instead you might consider using a timer-bevaviour, set it to 5 seconds

on timer

create

set timer for five seconds

Regenerating the obstacle path every tick doesn't sound very usefull

Add a trigger once condition

crawl is false

sytem trigger once

• solid2 set y to 131
• regenerate obstacle map
• find path

crawl is true

-- systen trigger once

solid2 set Y to -100

regenerate obstacle map

find path

-- on path found

...etcetera....

after regenerating the obstacle map, you will have to find the path again..

You can check if the animation is playing

You can even check the frame of the animation

Sprite - is playing animation

Sprite - compare frame

I usually do it this way:

you have two events "on highscore get", one setting it to 0 and one setting it to localstorage.Itemvalue..

When not in touch the value of touch.x = 0 as is the value of touch.y..

So you will have to create an action to set the touch.x and touch.y to the desired x and y when not touching.

It should be as easy as using the choose() expression at the right place, but without knowing how you have your events set up untill now telling you where the right place is is pretty hard..

If it doesn't work on phone it sure isn't the action that doesn't work..

Probably your triggered event is wrong..

What is your event for making the player jump and what is the event for changing the gravity?

Would adding a system trigger once condition to that event help?
