does anyone know how to fix this

protected Vector2 GetLocationInsideLevel()
{
return new Vector2 (UnityEngine.Random.Range (originOfLevel.x + maxObstacleRadius, originOfLevel.x + size.x - maxObstacleRadius),
UnityEngine.Range (originOfLevel.y + maxObstacleRadius, originOfLevel.y + size.y - maxObstacleRadius));
}
For this one I get an error message saying "the name size does not exist in the current context"

PlaceFirstObstacle();

while (NumberOfObstacles >= 0) {
yield return delay;
if(PlaceNextObstacle()) NumberOfObstacles--;

}
and for this one it says "the name PlaceNextObstacle does not exist in the current context"

 

First fix would be putting in code tag, so easier easier to read.

Is this your code?
Size is a vector in your case. It expects vector either in method or as global variable, outside method. Which probably don't exists.

Second part is taken out of full contexts, or PlaceNextObstacle () don't exists. Check spelling.

 

If copy-and-pasted this code from somewhere, it looks like some parts of the code are missing. in the first code, there should be a variable called "size" declared somewhere. In the second code, there should be a method called "PlaceNextObstacle" somewhere.

 

I declared a variable for "size" but then I got an error message for x and y saying "object does not contain a definition for 'x' and no extension method 'x' accepting a first argument of 'object' could be found"

 

Show the part, where you declaring size.

 

To add to Antypodish's request, I think it would be a good idea to just paste the whole file (assuming it is not too big) rather than trying to guess what we want to see. Also, please paste the entire error message, again, not just the small part you think we want to see.

Remember to use code tags:

Code (CSharp):

1. bool ShouldIUseCodeTagsWhenPostingCode()
2. {
3.     // Yes, you should.
4.     return true;
5. }

 

Checklist for a successful thread:

• use topic titles that describe the problem
• use code tags
• post the full code that is the problem

Also can I ask the community not to reply to any thread unless you want to actually help. Let it just fade away because it's a waste of your time, which could be spent on threads where people put some effort in (ie they're genuine cries for help).
