[tuto] Random jump

[O Ilusionista]

This is a code I made for my mod, to make the entity do a jump with random velocity.
Maybe there is a better version (like usin Atan to get the right angle/velocity, but I don't know how to do it yet).

Put this code into your animation script

void randomJump (int vx, int vy)
{
    // Douglas Baldan / O Ilusionista
    // version 1.0 - 23/07/13
    // makes the entity execute a jump into a random direction
      void vSelf = getlocalvar("self"); // Gets the caller
      int Xr = rand()%vx;    // Random X vel, between the chosen velocity
      int Yr = 2+rand()%vy;    // Random Y vel + 2, to ensure a vertical jump, between the chosen velocity
      if (Yr <0){            // If the Y is negative,
        Yr = Yr*-1;            // Make it positive
      }
      changeentityproperty(vSelf, "velocity", Xr, 0, Yr); // Change entity velocity
       }

Usage:
@cmd randomJump 3 4

The first value is the x velocity, the second is the y velocity.

Any improvement, feel free to share.

Thanks for share on that jump script, O! ;D

I assume this topic has to be moved to Scripting section since this topic is about script.

you hydra golem uses this code when he jumps?

is a cool behavior for bosses, im using my jumps on rise attack animation but random jumps are cool feature for enemies too

 

[O Ilusionista]

No, Golem uses the TargetLeap function, from Blood. On the beta I sent to you, I think he used just the leap function, which makes him jump based on his Z position. The newer version uses the TargetLeap, to try to stomp the char.

The Guardian enemy uses the leap without jump, just the Z logic. Take a look that it always jumps to the other "side" of the his Z position (ie, if he is at the lower part, jumps to the higher part and vice-versa).
