Constrain doesn't constrain

Hunnenkoenig

I made an actor, which I want to move constantly as long as I touch the screen.

If actor touch pressed
constrain attribute self.Position.X to self.Position.X+5

That's all.
Now, if I touch it, it moves to X+5, then I have to release the touch and if I touch it again, it moves constantly, like I want it to move.

So it is beyond my mind, why the first time it only moves +5 and stops?
There is nothing else in the whole project, just this actor with this rule.

I think, it is a bug.

I've got the same as you. Just tested it in a project.

Thanks Tshirt, but it is not useful for me.
I assumed, that somebody will come up with this.

The problem is, my above post is only an example.

I don't want to use touch in my project at all, I just made this, to test, why my constrain doesn't work.

The finished project will move the actor by accelerometer, but to test teh functions, I built in keyboard and mouse functionality.

So, I need it so, that if I push a key on the keyboard, or touch the screen and hold it, it will move, without haveing to move the mouse.

I could have made the example too:

If actor key right down
constrain attribute self.Position.X to self.Position.X+5

Ok, this may be a workaround, but this doesn't explain, why it works afterward and not for the first time.

The bug still exists.

Thanks anyway.

EDIT:
The timer solution makes my movement jerky as hell. Even if I use 0.01

I remember that in the release note, it have said that the constrain behave can't do this as the old version!

@Hunn, For the timer based solution, you'll need to use interpolate for the movement w/no easing. Just set the interpolate to take a little longer than the timer's frequency, that way it will never complete.

Thank you for the answers.

I test it now in the gamesalad viewer and it works fine with accelerometer and constrain.

I made an endless doodlejump clone within one day. I just have to polish it further and add some features.

When it is on the appstore, I will upload the project for free use probably.

BTW: look out for our newly released game "Assault Commando", which is #50 in all games and 15 in arcade (apple messed up our release, so we are not in action until the update comes out)

Cool! Do you mind if I ask what you guys used to develop "Assault Commando"?

Hunnenkoenig

It was developed with Unity.

Next game is developed with our own engine. Will be released hopefully in october.
