this is build1

this is build2 and monobehavior “Rainbow” works like this

i exported the monobehavior and monoscript files from build2 then added a new monobehavior and monoscript file on build1. overwriting them with what i exported. editing them and gameobject cube so they would be connected. i also copied and pasted “Assembly-CSharp.dll” from build1 to build2(there was no “Assembly-CSharp.dll” in build2) but still nothing happend. what should i do?
