Hi.

I created a Sprite and add static Physics with SetSpritePhysicsOn(spr,1). now in Elsewhere I need change Physics Mode to 2 (dynamic) but I don't know how can do it.even I can't find any function for change Physics mode.

Please Guide Me.

Thanks.

Delete the Physics and then re-add with the new mode...

SetSpritePhysicsDelete(spr)
SetSpritePhysicsOn(spr, 2)

Thank Funnell7.

but this way make exist the problem. when I delete old physics and add new physics mode, my sprite slow move down.while Set Physics Gravity is exist and other physics sprites are ok.

If you change the physics mode of a sprite to 2 it will become a "dynamic" sprite (one that will be affected by gravity, other forces and sprites). If you want the sprite to not be affected you should change the sprite to physics mode 1 (static-which will not be affected by other physics but which will affect other physics sprites) or 3 (kinematic-which can have its velocity and angular velocity set but which will not be affected by other physics and will affect other physics sprites).

You could think of it as follows:
1-Static-Cannot move but can get in the way
2-Dynamic-Can move, be moved and get in the way
3-Kinematic-Can move, cannot be moved and can get in the way

Have you seen or read the help files? They really do 'help'...

I think you don't good understand my mean.my physics sprite at first is static mode.then I want change it to dynamic (mean mode 2).now when change it to dynamic,no have real dynamic physic and fall to down very slowly.

Ah, you probably just need to experiment with "SetPhysicsScale"

Put it at the start of your code (before you create any physics sprites) and start with a value around 0.01 going lower will make things move faster and going higher will make them move slower.

use "SetPhysicsScale" make exist problem for all physics sprites and Everything is destroyed. I think use "SetPhysicsScale" is not good idea for fix this problem because other sprites that have Physics no have any Problem.

Ok, you know best... it could be that you are affecting the physics of this sprite in some other way. Again this is not something that can be fixed in the dark. You may need to share some code.
