Hi.

I want make a platform game and wrote a code for move view depend on move player, but It don't work good.

this is my code:

+ Code Snippet

SetDisplayAspect( 4.0/3.0 )

global Player as Integer
global back as Integer
global ground as Integer

SetPhysicsGravity(0,100)

SetPhysicsWallLeft ( 0 )
SetPhysicsWallRight ( 0 )

//Create Player
Player = CreateSprite(0)
SetSpritepositionByOffset(Player,30,92)
SetSpriteDepth(Player,0)
SetSpriteColor(Player,255,0,0,255)
SetSpritePhysicsOn(Player,2)
FixSpriteToScreen(Player,1)

//Create Background
back = CreateSprite(0)
SetSpriteSize(back,GetDeviceWidth(),GetDeviceHeight())
SetSpritePosition(back,50,0)

//Create Ground
ground = CreateSprite(0)
SetSpritePosition(ground,0,95)
SetSpriteColor(ground,0,0,255,255)
SetSpriteSize(ground,GetDeviceWidth(),6)
SetSpritePhysicsOn(ground,1)


do

if GetRawKeyState(39) = 1
    SetSpritePosition(Player,GetSpriteX(Player)+0.5,GetSpriteY(Player))
else
    if GetRawKeyState(37) = 1
        SetSpritePosition(Player,GetSpriteX(Player)-0.5,GetSpriteY(Player))
endif
    endif

SetViewOffset(GetSpriteXByOffset(Player),GetViewOffsetY())

 Sync()
loop

Please Guide Me to wrote a Platform view.

Thanks.

What exactly do you mean by 'but It don't work good'?

Firstly, if you want the player to move around in world coordinates, you do not want to fix him to the screen...

Secondly, I assume you want the player to remain centered? If so, you want to set the view offset at the character position -half the screen size...

For example, you'd do something like this;

SetViewOffset(GetSpriteXByOffset(Player) - (GetVirtualWidth() / 2),GetViewOffsetY())

This will keep the player in the center, and assumes you are using Virtual Resolution...

I use Percentage system and used:

+ Code Snippet

SetViewOffset(GetSpriteXByOffset(Player)-50,GetViewOffsetY())

This:

+ Code Snippet

if GetRawKeyState(39) = 1
    SetSpritePosition(Player,GetSpriteX(Player)+0.5,GetSpriteY(Player))
else
    if GetRawKeyState(37) = 1
        SetSpritePosition(Player,GetSpriteX(Player)-0.5,GetSpriteY(Player))
endif
    endif

Should be this:

+ Code Snippet

if GetRawKeyState(39) = 1
    SetSpritePosition(Player,GetSpriteX(Player)+0.5,GetSpriteY(Player))
elseif GetRawKeyState(37) = 1
    SetSpritePosition(Player,GetSpriteX(Player)-0.5,GetSpriteY(Player))
endif
