Object delete code

[laserfishy]

Setting density := 0 crashes phun/algodoo, but i want my object to delete!

solution: set airFrictionMult:= -inf and the object deletes itself instantly

[hiltropper]

it crashes? on my pc , both works

[Someone Else]

I was told that density = 0 will crash Phun.
Setting just about anything equal to NaN will delete it, but may also delete some other things that you want to keep.

If you have algodoo, you can also set the inertiamultiplier to 0, hehehehehe.

Density=0 indeed crashes phun.
AirFrictionMult=-inf deletes object, but that object exerts infinite force at anything it touches, deleting it too. Good way to avoid this is to set collideset to 0 first.

[hiltropper]

okay didnt know started scripting after i bought algodoo so never tried some scripts in phun

I dunno if this is common knowledge or not, but to delete a spring, set the length to +inf or -inf.
This will delete the spring without affecting anything else.

I did not know of that. Thanks for sharing.

Here another way to delete the object:
Works only in scenes without water but it does not effect other objects, even hinged or fixed to the deleted one.

Code: Select all

(e)=>{e.geom.liquify;scene.erasewater}

[Someone Else]

You can also delete by spawning two killers in the same place, or spawning one circle with infinite restitution and a script to change its collideSet and e.other.collideSet to 0. More complicated, but the best way I've found that should work in Phun in a vacuum.

I still haven't found a way to delete a hinge when there are no forces being acted upon it.

Setting an objects density to NaN works as well

[SyntaxError]

Wow, there are really many ways to handle this.

Should be put into the tutorial page

[Someone Else]

I actually tried density = NaN and it didn't work.

[bozbez]

I actually tried density = NaN and it didn't work.

In Algodoo?

[Someone Else]

In Algodoo. Maybe I made it not work by saying collideSet = 0; density = NaN? So the circles couldn't collide and then spontaneously delete themselves?

[bozbez]

Didn't test it in Algodoo.
It shouldn't matter if you change the collideSet, but you don't need to.

[Chronos]

You don't use density = NaN for Algodoo, do you? I thought you used density = 0.

[Someone Else]

I tried and failed to use density = NaN because it should work in Phun.
