[Question] Wave Effect Port (Help)

[REALMUGEN]

Hi

I am trying to adapt the Wave Effect script by Zecomeia and originally edited by Wecoc.

Said script generates a wave effect on the graphics like in VX.

In my project temperature plays an important role, so I'm looking to be able to generate a heat effect on the screen. So far I have achieved that when using the script, all the Sprites eleents acquire this effect, but for some reason they only do it in the loading screen, once I return to the map I can't get the effect or call it.

I would appreciate any help.

(sprite).wave_amp = n

Where n is the amplitude of the effect, normally it would be 2 
for when it is active, but you can try other values. To deactivate it set it to 0.

You can also play with some other parameters like wave_length (default 72) 
or wave_speed (default 720) in the same way but generally you should only use wave_amp.

$game_player.wave_amp = n (for the character)
$game_map.events[ID].wave_amp = n (for an event)
$game_screen.pictures[ID].wave_amp = n (for a picture)
