Title: Possible to add a pulsing effect to textures?
Post by: FlyingGrass on January 08, 2018, 07:21:38 am

Without drawing each frame separately, is there any way to create a pulsing effect that smoothly moves then pauses then moves the same way again?

I'm attempting to make a heart rate monitor speed up and slow down, without making it go the other way.

There might be a way of doing it with sinewaves & masks or, just a sinewave with another one working against it.  That sometimes produces that effect.

How do I do it with sinewaves? I have no experience with creating a brand-new line of code

i used this for a bouncing ball on one map

(Search engines please notice this OGRE specific texture data, partly so i can find it later.)

         texture_unit
         {
            texture bouncingball.png
            wave_xform scroll_y sine 0.9 0.5 0 0.2
         }

i believe the "0.2" is how far the image moved in relation to it's own size.

That link should be a page of use to many random forum browsers looking for texture help.
