Well, your question was about user controls and you didn't provide much details about your game. If you have a small car driving around on the screen, then here is an updated demo:

If you are making a vertical scrolling game, like this, then you should probably use Bullet or some other behavior (not Car).

.

As for your second question - I had some programming experience, so learning Construct was easier for me. But I actually improved a lot and learned hundreds of new things and tricks when I started reading and posting on this forum. Also google is your friend :)

You can't really protect your game from hackers, the best you can do is make their job harder.

I'll quote my answer from a similar post:

You can keep your score hashed at all times. Check if the hash is correct before adding points or submitting the score.

Or keep track of the score in 2 different variables - one in clear form and another in some encrypted/obscure format. (Multiplied by 3.14, converted to text, written backwards etc.)

Display the clear variable in your game and don't check its integrity, allow the hacker to change it. But when it's time to submit the highscore, de-crypt the other variable and upload it.

There are several ways to do this.

You can keep track of Touch IDs - check when each one starts and ends, but this is probably the hardest method.

You can use "Nth touch" events and expressions Touch.***At(). For example if two fingers are touching the screen, Touch.XAt(0) will return X for the first touch and Touch.XAt(1) for the second.

And finally, you can place two big invisible sprites, one on the left side of the screen and one on the right. And then simply check "Is touching object LeftSprite -> Run", "Is touching object RightSprite -> Jump".

The common trick is to use an invisible rectangular sprite with Platform behavior and simple collision polygon. You need to remove Platform behavior from the character spite and pin it to that invisible sprite.

You can try a combination of Pin+Pathfinding.

Pin an invisible sprite to your character (with "rope" setting), which will act as a target for Pathfinding. And then use Pathfinding to move the actual party member to that sprite position.

They can work together if you are not using them both at the same time, or if you are not dragging your paddle over any solid sprites.

You can add another event - if paddle is dragging, disable 8direction, else enable 8direction

It's because the paddle has 8-Direction behavior, and objects with 8-Direction behavior can't overlap Solid objects. It doesn't actually disappear, it jumps to the left or right edge of the wall.

If you want to limit the movement of your paddle, you should use an event like this:

Paddle is dragging -> Paddle set Y to clamp(self.y, 100, 600)

Are you talking about the persistent storage?

Just search for Local Storage tutorials (they are the same for C2 and C3). For example:

Here is a basic example. You might need to tweak it for your game of course.

If you add "ID" variable to the object, you can use it to pick object instances. You can also pick by UID, IID and several dozens of other criteria.
