Hello everybody

I am trying load a title screen before the game loads.

load image "media\backdrops\Starting_Screen copy.png", 11
do
if stage = 0
paste image 11, 1024, 768, 32

if spacekey()
stage = 1
endif

endif
if stage=1

Function Init_game()
endif()

This is the code above but I keep getting an error message saying
"FUNCTION FunctionName (Function Parameters)" The highlighted code which has the error is the second last line of code in the code snippet above.

I do not know how to fix this error message. Please can somebody help me out. Many Thanks.

First off, the "do" has a missing "loop".

endif() should be endif with no parentheses.

Your functions must be separated from the main program.
Function Init_game() shouldn't be placed where it is, it's also missing an endfunction.
If your intention was to call the InitGame() function, then you should call it by using InitGame(), not Function InitGame()

There are also some logic errors, specifically with your if spacekey() statement. If the intention is to wait for the user to press the space key to continue, then you should add a condition for this. As it is, the program will not give a chance to press the space bar and it will continue until it crashes when it finds function in the middle of the code.

I made some updates to get you on the right track.

+ Code Snippet

load image "media\backdrops\Starting_Screen copy.png", 11

if stage = 0
	paste image 11, 100, 100,1 
	repeat :	until spacekey() 
	stage = 1
endif

if stage=1 
	`Function Init_game() 
	Init_game() 
endif

end	` End Program

Function Init_game() 
	` Function code
ENDFUNCTION

Generally, you want to call sync after displaying something and before loading something else. As CSL stated, there are some issues with your code, and simply loading an image won't display it, just load it into memory.

New sig coming soon..

And note that paste image does not take ID, width, height, depth as parameters as you seemed to assume in your code, but ID, x, y [, transparency flag]. Your IDE probably tells you what parameters a command expects at the bottom of the window, right below the code.

Try this.

Ps. the error message you're getting telling you that the program thread has ran into the function declaration at the bottom. This is because you haven't closed the loop.

There's nothing wrong with that.

The following snippet works perfectly for me:

+ Code Snippet

sync on : sync rate 30 : sync

do
  cls
  if spacekey()
    text 20, 20, "pressing space key"
  else
    text 20, 20, "Not pressing space key"
  endif
  sync
loop

end

Gandalf is right. spacekey() returns a boolean value(on/off) so 'if spacekey()' is logically correct.

In my main loop of the game, I already have a init_game function. Will I have to get rid of this init_game function? Also does the code below need to go in the main game loop?

[/code]
load image "media\backdrops\Starting_Screen copy.png", 11

if stage = 0
paste image 11, 100, 100,1
repeat : until spacekey()
stage = 1
endif

if stage=1
`Function Init_game()
Init_game()
endif

end ` End Program

Function Init_game()
` Function code
ENDFUNCTION[code]
