Increase/decrease slider

SingleSparq

Hi - I have a slider that moves on touch right or left. How can I get it to increase (moving right) or decrease (moving left) an integer attribute with a limit on the plus or minus (say middle was 100 can go max +100 and -100 in left right when moved. Any help is appreciated!

Make an invisible actor saying that if that slider collides with the invisible actor either increase or decrease the amount.

Yes, never thought of that, will try. I thought it might be more a math thing where if movement to the right or is a calculation but I guess there is more than one way to do things. Thanks!

No problem! Always glad to be of help!

Hmmm... tried it and it will technically work but it misses the granularity of the integer.

If you were only going up to 100 in increments of 10 you would need 10 actors to get to the plus 100 and worry about the decrease (going up would increase with each overlap so you would have to make 10 booleans to switch them to "on", then add some timer cause you can't be overlapping for more than a certain time or it will switch to false etc. etc.

Will keep trying it though.

found firemaples' demo - that should do it:

How does one mark this resolved?

Currently, posts in the tech support category have the ability to marked 'resolved' and 'not resolved'. I went ahead and moved it into that forum and have marked it 'resolved'.

Re-dredging this again - the slider works fine, but it only goes from 0 to 1 in .01 increments. What controls this? If I want the slider to control a set parameter up to 100 nothing I change in the setting or my attribute seems to change this - is it the floor( self.Position.X - self.leftLimit )/( self.rightLimit - self.leftLimit ) formula?

I made that slider to adjust the volume, which just goes from [0,1]. To get a different range, you just need to do some math.

In that example, I have it clamping down to 0 and 1 with Rules, something like: When The musicVolume < 0 change musicvolume to 0, and when musicvolume is > 1 change musicvolume to 1. You will need to delete those two rules if you want a larger range.

And you can get rid of the 'floor', you don't need it. Unless you want to strip off the decimal.

So, for example, if you want the range to be [-100,100] change the formula to look like this:

((( self.Position.X - self.leftLimit )/( self.rightLimit - self.leftLimit ))*200)-100

Hope this helps!
