How Do I Increase Speed Of Enemies Overtime?

Peace Unto You! I’m making this game and I need to know how to increase speed by a certain amount every 5 seconds. I got the first part as in setting up the locals, but it’s the functionality I’m having issues with. I got it to where at a certain moment the enemies increase their speed but it’s not an overtime thing.

Please help me!
Thank you, we’re very grateful!

local initial_speed = 200

local speed increase_rate = 50

local speed increase interval = 0.1

local speed timer = 0.0

function update (self, dt)

speed _timer = speed timer + dt

if speed timer s=

speed_increase_interval then

initial speed = initial

_speed +

speed increase rate

speed timer = 0.0

we’re not very grateful!

Haven’t you already asked more or less this question already?
