|placement||The PlayHaven placement name (a string)|
This function will preload a PlayHaven ad into memory, ready for
it to be shown when the
ads_event calls the placement
used (both functions require the same placement name string
to work. If you know that after a certain time or at a certain
point in your game you are going to be calling a PlayHaven content
placement, then this function can be called beforehand so as to
make the user experience as smooth as possible.
NOTE: This function will not show the ad! It only loads it into memory.
The above code will preload an ad from PlayHaven for the placement named "game_start".
