platform.lua keeps being disabled

[Slastraf]

Hello

My problem is that I have an Pivot which has the platform.lua script attached.

when I test it out and select it to be enabled at the program start, everything works just fine.

The pivot with all the atttached models are moving right where I want them and at the right speed.

 

But when I select it to be disabled at the start of the program, it just keeps locked.

I am pretty sure when you are ingame you cant make it change or just start inside the game.

I tested it inside flowgraph editor with multiple ways : collision, pushbotton (none of them work)

 

It am very confused about that since the most part of the script is in update...() functions.

So how do you can make it change (via flowgraph) ?

Try creating a collision trigger. In the flowgraph connect "collision" to "enable"

theres the problem. it just doesnt move (when you go make it enable at program start, it is Ok. Thats why I opened the thread

Does it have mass? And is there a target pivot?

Yes, just checked everything. When I enable this at start it does move.When I am ingame it deosnt as said

There were some things that were missing from the platform.lua that I have added. It is commented with what I changed.

 

Basically what happened is if you start disabled or disable it in game, The script set the platforms mass to 0. When you enabled it it did not restore the original mass causing it to not move. The fix was to restore the original mass to the entity when enabled AND you have to give it a little push to get it moving again.

it works now. thnaks
