[SCRIPT] Gradient Bars (all bars)

Well-known member
coding is not my forte, so if its overkill i apologize but it works with gradient colors for all players life bars individually so each
player can have its own color if you choose to, and 1 shared gradient for enemies and mp bar.
player 4 is untested but it should work , i am using 3 players and they all work accordingly so far xD
please from the pros, feedback on it would be appreciated as this took me all day smfh, am getting old lol
again everything works here on engine 4.0, and is its crappy please remove at will :)
of course youl have to adjust the numbers to fit your game and am using the same numbers for the y and x that i use in levels.txt file

I use it in update.c script as updated.c doesnt seem to work for me.
if theres a better way let me know please as it is my first time posting anything like this >_>
thank you.

Example in game look, just know that each player can have different color gradients... like p1 to p4 can be different if you chose to.
enemies only use 1 color gradient.

in levels text is where you set your bar positions and sizes, and those numbers then you use on the script for each matching setting.
the rest can be moved using the Xoffsets in the script along with gradient color choices.

Looks good :) I only suggest adding some visual examples for people to understand how the effect works when active.

Yes friend, it's exactly that. It's a cool script, congratulations!

found out this script works better in update.c than ondrawscript.

Exactly, for progress bars I recommend updated.c due to the consistency and accuracy. But I recommend putting only important functions on it to not overload the event.

Another thing I recommend is to use the updated.c instead of the update.c unless you need to interrupt key presses before the engine processes it. It's because the updated.c runs at the end of an engine cycle, meaning that the engine already did everything it needs and your script can run with no worries.

For a few small scripts it will not show differences in practice, but if you have many things running at the same time it may present performance issues. I tested it in my first SOR2X versions, where I was using too many scripts in the update.c and the performance dropped severely mainly during special effects, like shadow trails.

sweet thanks for the info and updated 1st post to reflect that.

EDIT: now i remember why i didnt use updated... doesnt seem to work. sorry thats the extent of my knowledge lol
 
oops fixed the code so it wont show up in mainmenu after you quit the game... it should only show in game now... apologies
