How do I change value of variables by name?

Hello everyone,

I got the name and its value from JSON.

Then I want to reach the variable and change its value.

Is there any way to do this with Construct 3?

Thanks.

You mean access variable by its string name? It's possible with scripting:

runtime.globalVars["myglobalvar"] = 123

Ashley warned though, that string syntax like that will be broken in advanced minification mode.

Hi dop2000

I tried and it works well.

So is it possible to do with multiple names.

For example:

- In JSON, I set a variable in text like [gameState = 10]

- I retrieved name and value from JSON.

- I used the script to set value to runtime.globalVars.gameState = 10

- Could we dynamic the gameState then we can set value for another variables?(gamestate001, gameState002,..etc.)

Thank you!

Yes, but you need to use a different notation -

instead of runtime.globalVars.gameState = 10

use runtime.globalVars["gameState"] = 10

If you extracted your variable name from JSON into another variable VarName, then your script should look like this:

runtime.globalVars[runtime.globalVars.VarName] = 10

Wow, thank you! It's perfect ^_^!
