What should lennaert see?

Seems like the complete answer is there..

Al you'd have to do is make the events and actions like he explained..

"but it doesn't seem possible to run a distance check as an object action... Is it"

Offcourse this is possible, would be weird if it wasn't, right?

You just have to pick the object in the event, as explained in "how events work"

the "system compare" condition doesn't pick, but a simple "system pick by comparison" does..

Another option would be to add the system compare condition to a for each object event..

Seems like you already found a solution in the thread you just reacted to..

Events and actions are given..

I guess that would have to be done the same way you add a variable in the middle of any other string..

"&variable&"

the first " closes the string

&variable adds the variable

&" is to open the string again

Each frame picture got around 10 kb.

Sounds like excellent image compression to me..

What size are they uncompressed?

Sounds doable..

All you'd need is 1 global variable telling which theme it is, and create the objects and play the sounds accordingly..

The way you set this up is up to you..

You could choose to use families (if you have a license) or animations..

Maybe using other sprites for the behaviours and pinning the animations on top of them..

It depends on what you are comfortable with and what suits your specific gameplay best..

I'm not sure I can do more, other than making the program for you..

I've given you every bit of information you need to complete your task..

If you understand your own events and the way Construct2 works, you should be able to make this work..

Re-arranging your events is just a matter of knowing when what should happen..

For example: You should only have to store information if the information has changed

For timed events using the timer-behaviour gets the best results..

You might want to try XAMP to set up a local testserver..

I'm guessing you are either looking for "local storage item exists" or following a tutorial that covers the depricated webstorage-object..

If the first is true, it should be a seperate event, because a triggered event cannot be a subevent of a triggered event..

If the second is true, please look for a tutorial about local storage..

actually if you put the action on the projectile right below the action spawning it, the spawned one will be picked by the action..

Edit: also using an "projectile on created" event should do the trick
