im trying to use ezrotate for rotations for my player objects but Im getting inconsistant results as using ezrotate with sin/cos does not seem to work right.

I can't[u] just use move object as im dealing with moving a dark physics rigid body that has force being applied to it while being regulated by a cos/sin algorithm.

Also the rotateto commands result my object pitching to the target then disappearing and if i try to move the program crashes

My goal:

1: get an improvised dark physics character controller working

2: have its movement to be flexible enough for move in the intended direction no matter its orientation.

3: Create several algorithms that allow my character to "walk around on" planets and other level objects

Could someone help

Can you post an example of this happening?

I figured out that since ezrotate returns angle values no larger than 180 for x and z and 90 for y, sin/cos wont work right as far as I know.

an example is this:

+ Code Snippet

sync on
sync rate 60

make object cube 1,1

do




EZro_LY mousemovex()

EZro_FindEuler

rotate object 1,EZro_GetEulerX(),EZro_GetEulerY(),EZro_GetEulerZ()

vx#=sin(EZro_GetEulerY())
vz#=cos(EZro_GetEulerY())

x#=object position x(1)
y#=object position y(1)
z#=object position z(1)

if spacekey()=1

z#=z#+vz#
x#=x#+vx#
endif
position object 1,x#,y#,z#
sync
loop

Play around with this code and you will see what I mean.

I hope you can help me with this as I really like your plugin
and you seen very devoted to helping people with it.

Thank you

Here, try this:

+ Code Snippet

sync on
sync rate 60

make object cube 1,1


do

EZro_SetEuler object angle x(1),object angle y(1),object angle z(1)

EZro_LY mousemovex()

EZro_FindEuler

rotate object 1,EZro_GetEulerX(),EZro_GetEulerY(),EZro_GetEulerZ()



if spacekey()=1
   movedistance# = 1
   x#=object position x(1) + (movedistance# * EZro_GetMatZX())
   y#=object position y(1) + (movedistance# * EZro_GetMatZY())
   z#=object position z(1) + (movedistance# * EZro_GetMatZZ())

   position object 1,x#,y#,z#

endif

sync
loop

Sorry, I don't have time to explain how it works right now. Basicly, it uses the object's rotation matrix to tell the object how to move.
I hope this helps!
