Hi, I have following problem:
Every time I want to test my game, I get following error messages:

COMPILATION ERROR in Script: script5
Error in code at line 24:
} else if(vspeed == 0){

at position 10: Unexpected symbol in expression.

or

COMPILATION ERROR in Script: script3
Error in code at line 15:
//Facing

at position 10: Unexpected symbol in expression.

I don't know, what has happened. Where are the errors?? I can't find them...
I use Windows Vista Home Premium. Can anyone help me, please??

PS: Sorry for my english.

It could be a couple things I'm not sure

#1 it looks like the brackets -- eg {} -- are facing the wrong way

#2 I've use the double = when dealing with vspeed

#3 thrre try getting rid of the regular brackets,

As I said I'm not sur if these things are causing the error.

I'd have to take a look at the script

I assume the compiler got the line wrong, as there can be no error in the line
//Facing

Could you show the entire code near the error? There's nothing wrong with those two lines, a double equal-sign is right and the brackets don't appear to be faced wrongly.

Do notice that this question belongs at the GMC!

You'll need to show the entire script if you want anyone to help you.

Ok, here is one script, where the error appears:
The error appears nearly in every line in all my scripts

//(C) Shadows-Light-World.de
if(collision_point(self.x,self.y,obj_ladder,false,false) ==true){
//-----------------------------------------------------------------
//With ladder
self.sprite_index = spr_hero_climb;
//No-Key
if(keyboard_check(0)){
self.image_speed = 0;
self.image_index = 0; //SubBild 0
} else {
self.image_speed = 0.5;
}
//-----------------------------------------------------------------
}else{
//-----------------------------------------------------------------
//without ladder
//jump fall
if(vspeed != 0){
self.sprite_index = spr_hero_left_jump;
} else if(facing == 'right'){
self.sprite_index = spr_hero_right_jump;
}
self.image_index = 0;
self.image_speed = 0;

} else if(vspeed == 0){
//Facing
if(facing == 'left'){
self.sprite_index = spr_hero_left;
}else if(facing == 'right'){
self.sprite_index = spr_hero_right;
}
//No-Key
if(keyboard_check(vk_left) == true || keyboard_check(vk_right) == true){
self.image_speed = 0.5;
} else {
self.image_speed = 0;
self.image_index = 0;
}
}
//(C) Shadows-Light-World.de

I also get an error message when I start Gamemaker: Failed to set data for ''
maybe it has something to do with it

thank you all for your answers

" Failed to set data for '' "
Ok, I found this error in another topic.

I tried to run GameMaker as Administrator, this error is gone. But the compilation error is still appearing.
I also tried my script on anohter computer. No error at all...

Does anyone know, what to do??

Hint: Try using indenting and putting the curly braces on their own lines. When you do that, you should see something like this:

if (thingy)
{
stuff
}
else
{
stuff
}
else if // Hey, what do we have here?

You've got an "else" without an "if"! BINGO! Now, do that for all of your scripts and find the problems. Good coding standards go a long way!

Yes, it was a silly problem :-) ...

Thank you all for your answers, now it works fine.
