Tokamak Collisions problem ? bug ?

| Hey, I've been experiencing a problem with tokamak and classic blitz collision detection. Take a look at the code, try it like that it will detect the collision ground,ball perfectly! Now add ; to the size1 lines, and uncomment the ones size2 and see the collisions are not detected anymore??? how come ? any ideas? any solutions ? --------------------------- ;Set Graphics Graphics3D 640,480,0,2 : SetBuffer BackBuffer() ;Consts Const FPS = 50 : Const RBCOUNT = 1 : Const ABCOUNT = 5 ;Camera cam = CreateCamera() : PositionEntity cam,0,1,-20 : RotateEntity cam,45,0,0 ;Light light1 = CreateLight() : RotateEntity light1,0,60,0 TOKSIM_CreateSimulator 0,-10,0 ;The Ball ball = CreateSphere(16) ScaleEntity ball,1,1,1 ;<--------------Size1 ... ok ;ScaleEntity ball,2,2,2 ;<--------------PROBLEM HERE rbBall = TOKRB_Create() TOKRB_AddSphere rbBall,2 ;<--------------Size1 ... ok ;TOKRB_AddSphere rbBall,4 ;<--------------PROBLEM HERE TOKRB_SetMass rbBall,2 TOKRB_SetSphereInertiaTensor rbBall,2,2 ;<--------------Size1 ... ok ;TOKRB_SetSphereInertiaTensor rbBall,4,2 ;<--------------PROBLEM HERE TOKRB_SetLinearDamping rbBall,0.001 TOKRB_SetAngularDamping rbBall,0.02 TOKRB_SetPosition rbBall,0,40,0 ;Plane plane = CreatePlane() EntityColor plane,0,0,100 EntityAlpha plane,0.9 mirror = CreateMirror() abPlane = TOKAB_Create() TOKAB_AddBox abPlane,130,2,130 TOKAB_SetPosition abPlane,0,-1,0 ;collisions setup EntityType plane,1 EntityType ball,2 Collisions 2,1,2,2 ;The walls wallLeft = CreateCube() ScaleEntity wallLeft,1,30,65 PositionEntity wallLeft,-65,30,0 abWallLeft = TOKAB_Create() TOKAB_AddBox abWallLeft,2,60,130 TOKAB_SetPosition abWallLeft,-65,30,0 wallRight = CreateCube() ScaleEntity wallRight,1,30,65 PositionEntity wallRight,65,30,0 abWallRight = TOKAB_Create() TOKAB_AddBox abWallRight,2,60,130 TOKAB_SetPosition abWallRight,65,30,0 wallFront = CreateCube() ScaleEntity wallFront,65,30,1 PositionEntity wallFront,0,30,65 abWallFront = TOKAB_Create() TOKAB_AddBox abWallFront,130,60,2 TOKAB_SetPosition abWallFront,0,30,65 wallBack = CreateCube() ScaleEntity wallBack,65,30,1 PositionEntity wallBack,0,30,-65 EntityAlpha wallBack,0.1 abWallBack = TOKAB_Create() TOKAB_AddBox abWallBack,130,60,2 TOKAB_SetPosition abWallBack,0,30,-65 ;Torque torque# = 200 period = 1000/FPS time = MilliSecs() - period ;Main loop While Not KeyHit(1) Repeat elapsed = MilliSecs() - time Until elapsed ticks = elapsed/period tween# = Float(elapsed Mod period)/Float(period) For k = 1 To ticks time = time + period If k = ticks Then CaptureWorld torqueX# = (KeyDown(203) - KeyDown(205)) * torque# torqueZ# = (KeyDown(200) - KeyDown(208)) * torque# TOKRB_SetTorque rbBall,torqueZ#,0,torqueX# TOKRB_SetForce rbBall,-torqueX# * 0.1,0,torqueZ# * 0.1 ;Advance the simulator TOKSIM_Advance(1.5/FPS,1) PositionEntity ball,TOKRB_GetX(rbBall),TOKRB_GetY(rbBall),TOKRB_GetZ(rbBall) RotateEntity ball,TOKRB_GetPitch(rbBall),TOKRB_GetYaw(rbBall),TOKRB_GetRoll(rbBall) PointEntity cam,ball UpdateWorld Next RenderWorld tween Color 255,0,0 : Text 0,0,CountCollisions(ball) Flip Wend ;Destroy TOKSIM_DestroySimulator End --------------------- |

You have to tell the blitz collision system that the ball has a radius of 2:EntityRadius ball,2 |

| Oh man! thank you so much, I cant believe this, it's working ! :) |
| ||
| Pardon my ignance but what are the benefits of blitz collisions over tokamak collisions? Speed versus flexibility? I've just been using TOKAB_SetCollisionID, TOKSIM_SetMaterial, and TOKSIM_SetCollisionResponse and letting tokamak handle everything. thanks |

| Tokamak is way more flexible. But the reason we use tokamak is because it's a physics engine like HAVOK or Mathengine/Karma. Ragdolls, cars, crates etc... |
| ||
| Well, I presume it would be for a FPS or somthing. HRC_SPIDER - you know you can use tokamak collisions to detect stuff right? |
| ||
| Well, I have to admit, I did try using the tokamak collisions detection but after one day trying to make it work on my project, I started addind the classic collision detected from blitz and as it work perfectly now, I have been very happy about the result. Is Tokamak collisions detection is faster ? I am using collisions detecting to know if the wheels are on the ground, 1 or 2 or 3 .... it makes different cases... I would add tokamak collision with pleasure but I have to say, after 1 day trying, I am not sure if I can do it. |
