It might be simple but I'm a beginner and I need your help for this:
I want to create an emiter outside the layout spawning sliding colored segments one after the other, they should touch each other. Each of the segment will be created from 3 colored tilable bitmap (red, yellow and green, they will be tilable textures) and the emiter should never spawn 2 of the same color consecutively.
The emiter will spawn them during let's say 1 minute at a given speed and then stop emiting.
There are also 2 buttons to insert 2 other type of segments (brown & pink). Those 2 have a definite width.
When a button is pressed the next segment to appear will be one of those special segment. Then the other random segment should follow again.
I'm posting a pic to explain more visually:
What is the best way to achieve such a thing?
