Multitouch simple question

Hello again my friends,

I have a little problem with my project. It's very simple, but I just dont know how to make this work...

- I have a car in my game...and two buttons to make this car go to left or to right.

- I have a Active that aways its invisible, but if you touch on screen, this active will appear and stay on TouchX and TouchY positions (will follow you finger)

BUT....I want to make this happen in the same time...I want to be able to use ONE finger to move my active....and ANOTHER to touch on my button left OR right to make my car move.....or be able to touch in my button to move my car and in the same time use my other finger to make my active follow it finger on screen.

I dont know how to figure it out. If you can fix my MFA...i will be very pleasure.

BEST REGARDS, AND THANK YOU!

is this what you were after? if you want to have more than one active touch, you need more than one touch detector (though you can create multiple detectors of the same object and just assign a value on each new touch) this example is an easier way to understand the multi touch concept.

Hello again DaveC....you aways save me...this is exacly what I want..

But sorry to disturb....I have another problem....the two detectors that you have created will be invisible in my game..

AND...the big problem IS:

- I need to create a active (will be my aim) and make this aim aways stay on the same position of the detector that is DONT touching on buttons below...

I`ve tried here but cant figure out HOW can I detect wich detector that is not overlapping the button...then make my aim visible and stay on same position of this detector


Why I need this? Its because I will create a red laser that will go from my car to my aim.....the red laser I know how to create...scaling a small active.....but...I cant figure how to detect wich active is not overlapping the buttons..

Best regards

You might want to use a more dynamic method of tracking the multi touches in this case, I'm not 100% sure I understand what you were after, but I think this is it:

So now if the player makes a touch not on the buttons, the cross hair will follow the newest touch. If the crosshair touches the button it disables the cross hair aiming and waits for a new touch before aiming again.

DaveC...

this is exactly what I want!

You are the MASTER man!

I dont know how to thank you

thank you very very much!

Dave, nice examples. I have an issue as well. I want to move Left and Right and you explained that,.thank you! But I also want to touch on the screen to make the object jump. I would imagine I would need 3 buttons?? One for moving left, One for moving right and one for making the object jump? I wish there was a better way of doing this, but I can't think of a better way. This is a bump n Jump game. I would like it to be one button, but I'm sure it's impossible to do with one button. I guess the only way would be to use accelerometers. Tilt left/right to move and tap to jump. I don't like that though. I want it where you can press either the left or right button and have the object move and if you tap the object jumps also. So if you have your finger on say the left button to move left and with the other hand you tap,.i want the object to jump. I hope I explained this right!!??

Yeah, I guess that's the issue with creating touch phone gameplay.. no buttons! >_< attached is a file with 2 different methods, I've done these in a quick rush this morning but I think they both should work well.

The first one is probably more ideal for phone style gameplay (no buttons) but you do sacrifice maybe a little bit of the precise response time. The game determines whether the user tapped the screen or is holding down on the screen - if the user taps + releases the car will jump. If the user taps+holds for >10 frames, the car will move.

method 2 is just simple touch buttons.

Edit: you could also do a combination of the two methods, having left/right buttons and checking for a user tap not on the buttons for jump

Your example is great,..thank you. I did manage to set it up with buttons and Tap. It's working great. Again, thank you for taking the time to put the examples together.

Hello again friends,

DaveC, to not disturb you, I've tried everything to make this work like I want...but can't do it....so I'm here again.

If possible, can you try to help me again?

You example "mymultitouch 4.mfa" it's perfect, but there is 2 questions.

- If I start a second touch, the visible aim that have started with the first touch, go to the position of the second touch. The aim aways need to be in the same touch.

- When I release the touch that have aim, it need to create a active (called bullet) in same position of this aim.....If I have two touchs activated (one controlling the aim, another controlling the car), only the touch that have the aim create the bullet if released....so, if the touch that controls the car are released, nothing happens, just stop the vehicle..

I attached the example here:

Best regards and thank you very mich!

I didn't have much time this morning to throw something together before work, it's kind of hacked together >_< - I think this is mostly what you were after? I haven't fully tested on the device so it might need a bit more tweaking. I didn't have time to comment etc. I can explain later if you need that.
