Press specific key to change an object's collisionGroup

[AN9K]

Is this code correct?

Code: Select all

OnKey=(e)=>{
collisionGroup = (Keys.bind == 'v') ? 5 : 4
}

Not really...

The code is much simpler actually. You have to use keys.isDown("key"), keys.bind is only to bind keys to the GUI
First of all: If you write on onKey, your script will run more efficiently (no lag while not pressing the key) but when you release the key the script will not update (this means, you're saying: If you're pressing this key, change collideSet, if you release, change it again - but when you release it the script will not change the collideSet as it is not active). SO what you have to do is put it on the collideSet property itself (or on postStep or update if you want, but the script is shorter on collideSet)
So it will be like this:

Code: Select all

collideSet = {
keys.isDown("v") ? 5:4
}

That will make the object collision layer A and C when you press V, and only C when you release it

If for some weird reason you wanted to write that down on postStep or update, then do this:

Code: Select all

postStep(or update, same) = (e)=>{
collideSet = (keys.isDown("v") ? 5:4)
}

The particular thing about this code is that you'll be able to see which collideSet is active while the scene is running, from the script menu itself

If you need more help just ask. hope you don't do algicosathlon, whoever you are...

No.
keys.bind is interface customization for your PC only. Than bindings not saved with scene.
Use onKey or keys.isDown instead.
