Changing scenes after an objective is complete.

Question

Could someone help me write some code in C#. I just need a code that lets me change a scene after I completed the objective and collide with the goal post, but its impossible to change the level until they complete the task. I already have the script for collecting objects and counting them I just need to check if they have all the objects to proceed to the next scene.

 

Thank you,
