changing gravity (mass) in game script

[acd009]

I have have been trying make a object in my game switch its mass to 0 when i hit a button.

I am very new to leadwerks and dont know much about scripting but the very basics.

I found a script for doing this on one of aggor/ricks forums and for some reason it redirects me to a page that says sorry can not find that file. Did he remove the file or is there just something wrong with the page?

Looks like the gravity activator script is no longer there.However setting a mass is really easy:

self.entity:SetMass(1)

Is there a way to change a objects collision type in game using a script?

i ment like when you hit a button or lever

[AggrorJorn]

Can you elaborate what you mean with button? Keyboard button or something ingame. If you have a partial script please post it.

[acd009]

i mean if you were to use the collision trigger or collision button already in leadwerks.

Do you work with the flowgraph editor?

 

If you want to use a script and you want to set mass and collisiontype via script then use this:

function Script:Start()	  
    self.entity1:SetMass(1)
    self.entity1:SetCollisionType(Collision.Prop)
end

how do i add imput to make it work with the flowgraph editor? Like if I want to connect it to a lever with one of the collision scripts using the flowgraph editor.

Have you seen this video tutorial? :

Should I have the the script be called by in script start or update world or what?

[AggrorJorn]

Not really sure what you are asking in the post above. This is how I would do it:

 

You have a button with a buttonscript.

You have a rock/box with a ActivateMassScript. The rock/box has a mass higher than 0 and is of collision type prop.

 

 

The button script has a Flowgraph output called "button pressed".

The massScript has an input function called "ActivateMass" (or a name that you find usefull)

 

Inside the flowgraph editor you hook the output to the input.

 

The massScript:

• The Start function has saves the current mass to a temp variable and sets the current mass to 0.
  
• The ActivateMass function sets the mass back to original value, which is stored in the temp value.
  
• (instead of swapping the mass value, we can also set different collision types. it realy depends on what you find most useful.)

In my game I have logs (are collected from trees) and I have the same script that allows you to pick up barrels in the tutorial maps attached that makes them able to be picked up and I need that script so you can build shelters.

How could I make the logs have two scripts. I tried using pivots but it doesnt work.

[AggrorJorn]

You can either merge the scripts or use pivots. With pivots you do have to take in to account that the parent of the pivot is the object you want to retrieve first, because the pivot itself is nothing but a point in space.

[acd009]

So if I make the log the parent will it work

[AggrorJorn]

Can you post the scripts you are using?
