Trouble with adding field types and Gravity

First of all I'm trying to add types like this:

Player1\y = Player1\y + Player1\Gravity

But it doesnt seem to register the "Player1\Gravity" part but if I replace it with a number it works fine.

And my type player is defined like this:
Type player ; main player
Field Frame
Field Status = 0 Field x, y
Field TempX, TempY
Field Health, Lives, Score, Gold
Field DropFlag = 0
Field Gravity = 1
End Type

Last, is there a better way to add gravity to my player other than this?

Player1\y = Player1\y + Player1\Gravity
If ImagesCollide(Player1Anim, Player1\x, Player1\y, 0, WhatLevel, GraphicsWidth()/2, GraphicsHeight()/2, 0)
Player1\y = Player1\y - 1
EndIf

I didn't think that you could attach numbers and things to the fields like that "Field Gravity = 1"

Instead, try Player1\Gravity = 1

yeah,

Field Gravity = 1

Won't do anything. I'm assuming it compiles though, or it would be throwing up an error.

Field Status = 0 Field x, y

Does that even complie?

It shouldnt compile it. it should say something like:
Type declared incorrectly

Nope it compiled fine...I fixed that now. But does anyone know how to fix my gravity problem. By the way this is a 2d game, When my player walks off a hill my player doesnt keep "attached" to the level. Its like if you would to drive off a hill really fast you would be in the air for a bit. How can I keep my player "attached"?

do this:

Type player ; main player 
Field Frame 
Field Status
Field x, y 
Field TempX, TempY 
Field Health, Lives, Score, Gold 
Field DropFlag
Field Gravity
End Type

global p.player = new player
p\gravity = 1
;set all the other stuff too

;also
If gravity = 1
p\y = p\y - 5;whatever value you need
else
endif

OK, I have another question and I'm going to post it here instead of making a new thread.
Now I have a level like this:

+----------------+
|.........._..........|
|.........| |.........|
|-------| |-------| the periods represent nothing, air if you will.
|......................| the --- and | represent walls
+----------------+

And I need the player to stop when he hits the wall. My code looks like this:

If Player1\Gravity = 1 Then
Player1\y = Player1\y + 5 ; initial gravity
If ImagesCollide(Player1Anim, Player1\x, Player1\y, 0, WhatLevel, GraphicsWidth()/2, GraphicsHeight()/2, 0) Then
While ImagesCollide(Player1Anim, Player1\x, Player1\y, 0, WhatLevel, GraphicsWidth()/2, GraphicsHeight()/2, 0)
Player1\y = Player1\y - 1

Wend
endif
endif

But if I do this and the player collides with that wall, he will just "jump" to the top of the wall because of my While loop, any help please?

If anyone can help that would be great.

Player1\y = Player1\y + 5 ; initial gravity
If ImagesCollide(Player1Anim, Player1\x, Player1\y, 0, WhatLevel, GraphicsWidth()/2, GraphicsHeight()/2, 0) Then
If ImagesCollide(Player1Anim, Player1\x, Player1\y, 0, WhatLevel, GraphicsWidth()/2, GraphicsHeight()/2, 0)
Player1\y = Player1\y - 1

Wend
endif
endif

You shouldnt use this:



While ImagesCollide(Player1Anim, Player1\x, Player1\y, 0, WhatLevel, GraphicsWidth()/2, GraphicsHeight()/2, 0)

cause it will freeze
Use "If" It will update every frame so dont use while
It usually is 30 or more fps, so updating shold be no problem.
