Example: RGB coefficient Color Transition

[Chrille]

I needed a way to make smooth color transitions for a project of mine and decided to share the result here.

This example shows how you can change the color of an object using the 'Set RGB coefficient' function. Specifically how to make a transition from one given color to another and also determine the time taken using a given timer value.

Hope it will be of use to someone

Thanks mate !!

Very nice example. Thank you for posting it.

Chrille, this example can be used for some pretty nice effects in a game. I have a question. Is there away to set the color of and object and also the frame background color in the 1st frame and have the object/objects and frame background color to be saved so the object and background color is transferred to the game frame or 2 frame.

Example in frame #1:
1. You have an object and select "red" for it's color using your example.
2. You set the background frame color to "blue" using your example.
3. You start the game and jump to frame #2 and the object is "red" and the background of the frame is "blue"
Is this possible? If so how would this be done?

Thank you.

I would use an array. For example, when coloring an object, you write the color value to ArrayX(1) and for the background, you write the color value to ArrayX(2) and save the array file. Then, when frame two loads, you load that array file and set the object color to 'Read value from ArrayX(1)' and the background color to 'Read value from ArrayX(2)'.

Is that what you meant?

Yes Sir,.that's what I mean. I'm going to give it a shot. Thank you..

Thanks Chrille, this is exactly what I was looking for!
But before I create a new "How Do I..." thread, can you tell me which part of your code I need to allow my background to transition smoothly between a few pre-defined colours?
It looks a bit complicated for me.

Thanks!
