Slider to trigger an image switch - trueSpace WS

[Draise]

In the LE in Workspace, how would one evaluate a slider (float) value to then trigger a switch for a pair of bitmap images?

I know the code to switch node links, but.. have no idea how to evaluate a slider.

So...

If number change <1, run original switch once till slider stops moving
If number >1, run the second switch once till the slider stops moving

How do you do this?

How do you evaluate true/false = run script with nodes/jscript?

Ok, in the Activities - My Activities library I found an Activity example.

But it doesn't have a watchdog, and you have to trigger the evaluation. I'd want one that is always evaluating a slider, so I can animate the slider, and switch the image in a shader or visibility of an object accordingly.

Hmm. This would be awesome if I get this to work.

Here's a sample from my toolbars script that shows choosing different control outputs for running different scripts. The series of if, else if lines shows it.

I think sliders have an option to update continuously or only after release.

try this Draise.. you can change the bitmaps to floats or anything useful. One changes 10 images
you can write it like this too;
switch(func)
{
case 0:
params.ConValue('b2') = b1;
break;
case 1:
params.ConValue('b2') = bb;
break;
case 2:
params.ConValue('b2') = b3;
break;
case 3:
params.ConValue('b2') = b4;
break;
}

Wow.

You are legend Stan, that is EXACTLY what I needed, PLUS SOME!

The multibitmap switcher.. is AWESOME. I can totally create a 2D image/sprite character or lipsync system with that. Beautiful.

And it solves my issue! I owe you one for that!

Ok. I am using the bitmap switch, but you mentioned you could switch it to floats.

I would.. like it to execute a command now though.

Code: Select all

	Node.Value(Space.CurrentScene() + "/ACTOR/OBJECT/Object Render Attributes", 
		"Invisible") = 1

And vice versa.

.. could you give an example of changing it to something else? (I'm still learning..)

I tried using a Watchdog and a Zero Condition activity node, but I got errors on the D3D render, they couldn't execute a parameter.

I really don't know how javascripting if's and elses with a string of commands later on as a consequence.."Node.Value" etc.. I'll try study.

Ok, solved my issue using.. my rescale math nodes, offsets and binaryops linked to transparency, then a boolean fcurve interpolator that you Stan made! Works well enough for now.

Here is the basic idea using floats. If you just need true/false just reduce the number of float inputs. You can change the delivery system but you can't use Node.value('blabla') with a jscript object you must use a jscript command.
