Hey Everyone Smile i have a problem.. a made a "Moblock" hack with ASM.
(All mob x & y are set to player POS.)

But that gives me a big problem.

I can't attack them..
So i want to set there pos in front of my charakter.

But i don't know how.
I have my POS (X,Y) and my view angle. (0-360 float).

How can i calculate the position where the mobs have to be (see image)

Hope you unterstand.. Smile

Thanks for any help! Smile

(Should be posible in ASM XD)

sounds like basic trig. cos angle = X, sin angle = Y based on a circle with a radius of 1, to make them further away you just multiply by whatever factor you want, since cos(45) = ~0.7 to get a distance of 3 you'd need to use a factor of 3/0.7=~4.3 eg. 4.3 * cos A = X, 4.3 * sin A = Y

If you can use library functions for cos / sin then that's simple enough (example I made up via googling (so may not be optimal/perfect but seemingly working), based on the tutorial: dropbox github), otherwise googling "x86 assembly cos sin" should get you some code


of course you could just arbitrarily subtract 3 from the x position which should place them 3 to the left of the player and just require you to turn left to kill them instead of always having them in front of wherever the player is looking.

Thanks a lot! I was thinking that i need something like this..

But i was always scared of this (con, sin) because i thinking that there are to hard to learn.. (in the other hand math is my favorite subject area)

I'll try a little bit and watch how it works Smile thx a lot! Very Happy

Great
