You can keep the current position in an array, and add a sub event that checks if the current position exits in the array, if it does recall the spawn position again to chouse another positon.

Well I cant make the events without the sprite animation, if you can send me the player and all of its animation I can make an example capx file.

First you need to have the animation for the sprite, after that you will need a separate sprite pinned to an image point near the weapon for collision detection. Then you add an keyboard object to your project and add an event on key space pressed, and as action play the animation, make a wait system expression( 2 seconds or something like that), and reset the animation back to default.

As a sub event add the collision detection, use the sprite pinned to the image point and check if its touching the enemy, if it does subtract from his heath.

Construct 2 memory management is great and pretty efficient so its not that for sure, it has to do something on how you arranged your events. You probably don't destroy the objects that leave the screen so after a while they build up and its making the game to lag.

You can just copy paste the object in as many layouts as you want, it has no effect on performance. You can group your objects in subfolders and families.

Making more smaller layouts then one huge one is always a better choice performance wise, so you did the right choice.

You can add global variable movement and increment it by 1 on touch/click, when it gets to 2. Then add a second variable called stamina and set it to 100, when movement is at 2 and lets says say every 0.1 second, decrement the stamina by 1, when it gets to 0, stop the movement. You will need 3 events to implement it.

Give me the Capx file, I can make it for you.

You can use an array instead a global variable if you have to keep many values.

If you plan on making a multiplayer games, you will have to keep the data on a server, the date can file can be anything from json, XML or MySQL. But I suggest using a MySQL database, because its secure and its made to handle more requests at the same time.

You will need to find tutorials how to link construct 2 file to MySQL, because its not easy as it seems.

You can keep the players answers in a Json string or an XML file.

Or if it just a choice question where they just select things from already written answer, you can add a function to add +1 to a variable depending on what they pick, example you have 3 choices, 1 is apple, 2 is banana and 3 is avocado, if player selects apple, add +1 to global variable apple. In the end you keep those variables in local storage, or if its multiplayer game you keep them in an json or XML file which you load on start of game with AJax call.

I am hopping the mobile performance to increase by a great margin in the future, so developers can stop making the same games over and over again with just little changes to graphics.

I think the market is already overfull of freemium games, which usually revolve around same thing, grind a lot, buy upgrades and then grind again, I would like to see a change on this in the future.

Care to explain what happened?

I haven't used that plugin so far, maybe they are some tutorials available on the site.

Btw they are more problems to tracking time, because usually it uses your local time, which you can easy change to manipulate the game. So best solution would be to track some server time instead. I haven't implemented anything like that so far but one thing I know its pretty complicated so you will have to do tons of research on various topics to get it done.
