SDL TFF problem
Posted: Sat Feb 20, 2010 3:21 pm
I recently got back in the mood to program so I'm running through Lazyfoo's Tuts and I got stuck at Lesson 7&8 Using TTF files.
When I run my program with out TTF it builds and show the screen until I click X to exit out, but lately when I used TTF functions I get the program build and run and the screen just comes on go right off even do it's post to be event driven.
Here is my code. Little messy so :P I'm just thinking about skipping lesson 7&8 but its going to come back and bite me I know it.
