In the game engine, when i have my player walking around the scene it seems to slowly slide down slopes and ramps etc. How can I prevent this sliding from happening just like in most other games?

connect all the sensors you are using for motion to a python controller.

add a ray sensor, -z that will reach from the origin to below the actors lower collision bound. connect this as well,

sensors --------python


import bge

cont = bge.logic.getCurrentController()

own = cont.owner
Ray = cont.sensors['Ray']

your_sensor_1 = cont.sensors['YourSensor']

## etc

if not your_sensor.positive and Ray.positive:
##if you are on the ground and not pressing any movement keys like forward or backward 
## stop moving
  • $\begingroup$ You forget to set the ray sensor to true pulse triggering, but thanks anyway. It worked after that. $\endgroup$
