[Trigger] Angles

[NightSkyAurora]

Hi.

I want a projectile to bounce when it collides with a cliff. I got the angle right but I struggle to set the correct x-velocity and y-velocity from that angle.

Example

• What I gave
• What I want
• What I got

I believe that the problem occurs from where I calculate xyz_Vel (Total Velocity)

• Reflect
  • Events
  • Conditions
  • Actions
    • -------- Current Direction --------
    • Custom script: set udg_xyz_Angle = bj_RADTODEG * Atan2(udg_xyz_YVel[udg_xyz_Ref], udg_xyz_XVel[udg_xyz_Ref])
    • Game - Display to (All players) the text: (In: + (String(xyz_Angle)))
    • -------- Wall angle is the facing angle of the cliff --------
    • Game - Display to (All players) the text: (Wall: + (String(xyz_WallAngle)))
    • -------- Reflected Direction --------
    • Set xyz_Angle = ((2.00 x xyz_WallAngle) - (xyz_Angle + 180.00))
    • Game - Display to (All players) the text: (Out: + (String(xyz_Angle)))
    • -------- Total Velocity --------
    • Set xyz_Vel = (Square root(((xyz_XVel[xyz_Ref] x xyz_XVel[xyz_Ref]) + (xyz_YVel[xyz_Ref] x xyz_YVel[xyz_Ref]))))
    • -------- X/Y Velocity --------
    • Set xyz_XVel[xyz_Ref] = (xyz_Vel x (Cos(xyz_Angle)))
    • Set xyz_YVel[xyz_Ref] = (xyz_Vel x (Sign(xyz_Angle)))
    • Custom script: call SetUnitX(udg_UDexUnits[udg_xyz_Ref],udg_xyz_XCur + udg_xyz_XVel[udg_xyz_Ref])
    • Custom script: call SetUnitY(udg_UDexUnits[udg_xyz_Ref],udg_xyz_YCur + udg_xyz_YVel[udg_xyz_Ref])

Help will be appreciated.

Solved
I used the Sign function when setting the xyz_YVel[] instead of the Sin function.

Is xyz_WallAngle in radians or degrees?
