Since I'm not the original author, I won't try to tune it any further, but at least it works as a basic web preview.
I'd be very interested if there was some way to view all the source for the game in code format, but I guess that's a GM Studio feature?
Many thanks again
In obj_player on the collision event with obj_zombie a message is displayed that includes "quotation marks". Remove these quotation marks to resolve the issue.
However, GM:Studio also presented the following errors:
- In the object group Enemies there is an object named spr_guard1. I'll assume it should be obj_guard1 (Otherwise the naming conflicts with a sprite of the same name).
- In the sprite group Concert there is a sprite named spr_car6. This conflicts with another sprite by the same name, one should be renamed (spr_car7 seems logical).
- Sleep, is now an obsolete function. It may still be present in the version you're using? - But in GM:Studio the drag and drop is listed as "Unknown Function" in multiple collision events in obj_player and once in obj_flag, obj_flag_casino and obj_flaglouvre.
After fixing up these issues the game compiled successfully in HTML5, however there are likely other game play bugs that you'll need to play through to find and sort out.
