I was given this code by user Mickey4Fun and it works great, but how could I get the sphere cast slide to work with a rectangle? I have already asked Mickey and got no response.

endif

// position the player
SetObjectPosition(player, player_x#, player_y#, 0.0)
sync()

Hi gamergod88

I am usually only about weekends due to long weekday working ,

Quote: " but how could I get the sphere cast slide to work with a rectangle?"

now that's no easy as far as I can make out , without using the physics commands
using the physics commands will do this , but I have not tried any of them yet.

my example only works with round or square shape players ,
I think that you might be how to use the raycast command along with some maths to do what you want .

But you have now set me a challenge so Sunday I will attempt to find a way , but please remember its me a novice trying to do this

thanks
mick
ps anyone knows a way please feel free to jump in and not make me look silly !

Try this:



This will only look right with boxes that are parallel with the xyz axis.

Hi All

Thanks 29 games , nice example
was trying to do something similar , but could not quite suss it out , your code is in my code bank.

I don't think its going to get much more dynamic without using the physics commands
today I was mucking about with Stab in the Dark's examples and modified he's basic world set up example
so I don't know if this is any help to you gamergod 88


all good fun
mick
