create actor x y when touch is pressed

UtopianGames

Hi Guys,

Learning loads from this forum and videos etc but cant seem to find a solution for below,

Create an actor at x y relative to touch and if finger is still touching (pressing down on iphone) follow finger/touch....when finger is released destroy actor.

Actor will be a circle between 30-50 in radius.

Sorry if it's unclear whay im trying to do.

I'm not in front of my GS right now, but I believe you will have to do this:

Create a background Actor the size of the iPhone screen.
Create the small circle foreground Actor called `Target.`
Create a boolean Game Attribute called `SpawnedByTouch` that will hold the status of whether or not the foreground Actor has spawned.

In the background Actor, give it these Rules:
- if touch is pressed AND `SpawnedByTouch` is false, set `SpawnedByTouch` to be true, then spawn `Target.`
- if touch is released, set `SpawnedByTouch` to be false.

In the `Target` Actor, create this Behavior and Rule:
- Constrain Attribute `Target.Position.X` to `Mouse.Position.X.`
- Constrain Attribute `Target.Position.Y` to `Mouse.Position.Y.`
- if `SpawnedByTouch` is false, Destroy Actor.

Hope that helps.

Thank you i will try that asap.

Still having trouble with this.....tried what you said but cant find spawnedbytouch in the target actor to set it to false.

Do i need to create 2 spawnbytouch booleans (one for background and one for the target)...i did try this but it still didnt work.

I also changed the mouse.position to touch.position.

Hi tshirtbooth,

Similar..just looking at your code now.

Scene starts..no actor is in the scene.

Player touches screen and actor appears and follows the touch so player could move all around the screen with actor following.

Player lifts finger off screen = destroy actor.

Repeat.

I would do something like this:

Create a global game attribute (boolean) called something like "TouchingScreen".

Create an actor - a simple box is fine. Name it TouchController or something like that.
Place it in the Scene just out of view.

In the TouchController actor, create two Rules like this:

Rule
All
When Touch is Pressed
When game.TouchingScreen is FALSE
Change Attribute: game.TouchingScreen to TRUE
Spawn Actor

Rule
When Touch is Released
Change Attribute: game.TouchingScreen to FALSE

In the spawned Actor:

Constrain Attribute
self.Position.X To: game.Touches.Touch1.X

Constrain Attribute
self.Position.Y To: game.Touches.Touch1.Y

Rule
When game.TouchingScreen is FALSE
Destroy Actor

Hope this helps!

BIG thanks guys.

Hope to show you the game soon.

Really pleased i joined GS, you guys rock!

I can see where i was going wrong now....i was setting up variables in the actor instead of game.
