Get Material Color

[jeanfabre]

Hi,

 Following a request: http://hutonggames.com/playmakerforum/index.php?topic=1944.msg8603#msg8603

please find a Get Material Color action. It has an improvment over the Set Material Color because it checks first if the color property exists on that material. so it will fire an error, but simply a fail event.

Thanks a lot, working as expected 

[Derek Jenson]

Awesome, thank you!

[Slimshader]

Perfect! Thanks!

Apologies for digging up an old thread, but is there any reason why the GetMaterialColor action is not included with the default actions in the latest version of PlayMaker (1.7.7.2) on the asset store? Seems like it should be there.

[Lane]

Alex usually does add a few of the useful custom actions that feel like they should be stock in the package but not all of them because it would bloat the package with scripts that people rarely use.

[Pawl]

Ah okay, thanks for the reply. I just wanted to make sure it hadn't gone missing accidentally, seeing as there is a SetMaterialColor action =)

I couldn't find this action in the Ecosystem. Could it be added?

[jeanfabre]

Hi,

 Done, it's now available via the Ecosystem.

 Bye,
