Alpha: 255 = fully visible, 0 = Fully transparent
Orientation: Sets
yaw, pitch, roll all at once. I typically google "yaw pitch roll" to get an image of what each of them are, but note that they are in radians. I usually do something like this:
-
Special Effect - Set Orientation of (Last created special effect) to yaw: (Radians((Facing of my_specific_unit))), pitch: 0.00, roll: (Radians(45.00))
This makes the special effect face the same direction as a unit, and goes 45 degrees (Similar to the last slash in the GIF-preview on
Reaper's Claws)
Time Scale: 1.0 for "default speed" of the animation. 0.0 to make the animation "stop", 2.0 to double the speed. etc.
I use this to make a shuriken lay on the ground without spinning, or adjust a special effect to better fit an animation.
Time: Don't remember really, but IIRC sets the animation "time". I.E. if an animation is 1 second long and you call this with 0.5, it skips the first half of the animation. Not maybe you needed to set it to 500 instead of 0.5, but it's something like that... Not very commonly used by me.
