Polygon Error

Getting Started Newbie Questions
#1

Hello everyone,

I’m trying to create a polygon for a game I’m working on. THe basic idea is the get a ball into this goal: http://dl.dropbox.com/u/11226349/goal.png

However, Corona blacks out the screen on the simulator and returns the error message:
\main.lua:50: ‘}’ expected near ‘shape’

The code I wrote is as follows:

local goal = display.newImage("goal.png")   
goal.x = 130; goal.y = 420; goalShape = { -24,-29, 24,-29, 24,29, -24,29, -24,21, 16,21, 16,-29, -24,-29, }  
physics.addBody( goal, "static", { density = 1.0, friction = 0.3, bounce = 0.2 shape=goalShape } )

The lines correspond to lines 48, 49, and 50 of my program.

I’m not sure what I’m doing wrong. The polygon has 8 vertexes, and I’ve tried removing the space between the shape=goalShape code & } symbol, but I get the same error. Can anyone help me troubleshoot? [import]uid: 100403 topic_id: 20903 reply_id: 320903[/import]

YOU SAID:

The code I wrote is as follows:
[lua]local goal = display.newImage(“goal.png”)
goal.x = 130; goal.y = 420; goalShape = { -24,-29, 24,-29, 24,29, -24,29, -24,21, 16,21, 16,-29, -24,-29, }
physics.addBody( goal, “static”, { density = 1.0, friction = 0.3, bounce = 0.2 shape=goalShape } )
The lines correspond to lines 48, 49, and 50 of my program.

I SAY:

[lua]local goal = display.newImage(“goal.png”)
goal.x = 130; goal.y = 420; goalShape = { -24,-29, 24,-29, 24,29, -24,29, -24,21, 16,21, 16,-29, -24,-29, }
physics.addBody( goal, “static”, { density = 1.0, friction = 0.3, bounce = 0.2, shape=goalShape } )[/lua] [import]uid: 89165 topic_id: 20903 reply_id: 82402[/import]

Hello,

Correct RSC, also I believe there is a extra comma at the end
of line 49 after -29 and curly bracket :wink:
Good luck!

The missing comma was the problem. (I fell like an idiot…)

The program works now, but the ball seems to halt upon colliding with the air around the goal box. I assume I incorrectly wrote the vertex values (The goal appears off in the hybrid view), so I’ll get started on fixing that.

Thanks for the help! [import]uid: 100403 topic_id: 20903 reply_id: 82405[/import]

PS: Do not feel it, I say you because is with mistakes that we get read to make the right ones! :slight_smile:

What an awesome thread to come into - Rodrigo and Larry, good on you guys!

Oakes - when I was new to Corona I made about 100 errors like this, I still do it from time to time but I always know where to look now - so don’t let it get you down. It happens to everyone.

At least you haven’t made a thread nagging Carlos to help you with Facebook. (Yeah, I really did that.)
