Status Effect Issue

[V0RTEXwhoEditz]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I’m making an efficient Status Effect system for my roblox horror game.

2. What is the issue? Include screenshots / videos if possible!
   Only for the speed effect, I’m getting this error:

  10:54:38.265  WalkSpeed is not a valid member of Player "Players.superman978705"  -  Server - EffectHandler:32

5. What solutions have you tried so far? Did you look for solutions on the Creator Hub?
   ChatGpt, dev forum, everything lol

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.

Walk speed is a property of humanoid objects. You are passing a player object instead. Change plr in Effects[effectName](plr, level) to something among the lines of character.Humanoid.
