I'm working on a game where I want to choose which object to spawn based on probabilities. Meaning the object with the highest probability should have a higher chance of being spawn. An object with 50% spawn probability should spawn more often than an object with 15% spawn probability. I also need to account for instance where a game object has the same spawn probability

GameObject 1 .50 GameObject 2 .25 GameObject 3 .25

What's the best way to implement this logic?

I'm working on a game where I want to choose which object to spawn based on probabilities. Assuming the decision to spawn the object has been done by some other process, I'd like the object with the highest probability to have a higher chance of being spawned. An object with 50% spawn probability should spawn more often than an object with 15% spawn probability. I also need to account for instance where a game object has the same spawn probability

GameObject 1 .50 
GameObject 2 .25
GameObject 3 .25 

How can I implement this logic?

I'm working on a game where I want to spawn game objects based on probabilities. The issue is determining which object to spawn if two objects have the same probability.

For instance:

GameObject 1
  probability .02

GameObject 2 
  Probability .03

GameObject 3
  Probability .02

I believe the initial way to do it is, to sum up all the probabilities and get a random number to compare against the objects probabilities.

0.03 + 0.02 + 0.02 = 0.07

randNum = rand(0, 0.07)

so if randNum < .02 how to determine which object should be spawn?

Is this the correct approach?
