yes i saw many theards about it.. but i think i found a way how to do it

My idea is spawn info_null, and give mins/maxs, and give him classname or something, then check if player touching it - set velocity[2] to 250.0 (ah yea check the player pressing moving keys or no ? then add sounds and so on, also spawn at same place the model or skin or something else)

Have fun! 2morrow i will try todo something too

omg! i did it climbable, kinda weird, but i can climb on it + hear the ladder sounds!

I quess you can't never make a perfect ladder. Because you don't do it same way it's done in maps, it's not possible.

[xPaw]

yes, but its a progress so i did it climbable anyway oO

[ConnorMcLeod]

My attempt is not perfect (yet ?), i don't manage to stay with 0 velocity and also my velocity calculation is not perfect (yet ?).
I will need a model if i manage to code this better.

[minimiller]

Good job xPaw!

[Exolent[jNr]]

I have a good idea on how to get the velocity right, just let me get on my other computer in about 15 minutes.

[xPaw]

oke lets do LadderMaker, when do ladder perfect

[Exolent[jNr]]

Here is my idea for simulating the ladder movement.
I didn't add the ladder making to it cause I got lazy.

[xPaw]

Exolent watch demo of your plugin work

P.S. Download model.
