 === Description ===
 Sets the named variable on the specified unit script to a value.
+Can also set the variables of built-in units like spore towers and emitters.
+You can check the names of built-in variable for units on the [[crpl:docs:getscriptvar|GetScriptVar]] page or at the bottom of this page.
+<note>**Payload** and **Amt** values for Emitters, Inhibitors, Spores and Runners are internal integers, not the floats you would use in the map editor dialog. For example, 1.5 Creeper in-game should be set as 1500000.
+**Interval** values for Emitters, Inhibitors, Spore Towers, Runner Nests should be set as the number of frames, rather than seconds. For example, 2 second interval as shown in-game should be set as 60 frames.
+This is what setting an Emitter with 32.5 power and 2.5 second interval would look like:
+<code>
+SetScriptVar(<-unit 0 "productionAmt" 32.5 1000000 mul)
+SetScriptVar(<-unit 0 "productionInterval" 2.5 30 mul)
+</code></note>
+<note>The **"startTime"** variable of Emitters and Spore Towers works based off of the start of the game, not the time of unit creation.
+If you're procedurally generating a unit, and you want to give it a delay, you need to add the current time elapsed to it.
+This is what setting a delay of 10 seconds would look like:
+<code>
+SetScriptVar(<-unit 0 "startTime" 300 GetGameTimeFrames add)
+</code></note>
