GML Need an equation.

[Thunder Lion]

I am looking for an equation that will allow the following concept:

I have a fixed value, that must be modified by another variable.

They must be apart of an equation that results in being higher if the player reduces another variable and remain neutral toward the fixed variable if the player keeps this other variable untouched.

Again I have the variable swingspeed=16
I want to modify it with the variable energy.
If energy starts at 100, I want it to effectively make newspeed=16
But if energy is reduced by any means I want it to increase newspeed.

How can I accomplish this?

newspeed = swingspeed * (100 / energy);

 

[Thunder Lion]

newspeed = swingspeed * (100 / energy);

I love you, being half awake has taken my brain to the lower depths of Norfair Mathematics. Works great! I will test it out in the actual project.

 

[Thunder Lion]

newspeed = swingspeed * (100 / energy);

How can I prevent a divide by zero apocalypse?? I was thinking of this: (100/(energy+1))
If energy is 0 then:
100/1
If energy is -1:
100/0....
Oh nooo
Hmmmmm....how to solve this?? Oh maybe I can have a preventive measure like if energy reaches 0 make energy equal one with that I don't need the +1

Well you could ask yourself, does energy need to go into negatives? Does it need to go over 100 (or some other limit)? You can cap the value at both ends if there's no good reason for it to swing past those. For example 1 to 100. Or if you want it to be possible to go to zero, think what newspeed should be when energy is zero, and create a special case for that.

I did just that. My post stated one var but I'm combining 4 and it works great when my guys is low everything he acts like a sluggered but still can do work for gameplay sake. Thanks a bundle here take this.

newspeed = swingspeed * (100 / max(energy,1))

Lol. "Lower depths of Norfair Mathematics?"
I'm remembering that line!
