object collision problem

[Ninjor]

I'm writing a script that will cause an object to be created and move based on the player cars speed. I want the object to have collision, but it goes through walls.

 

Here's what I've written:

I'm writing a script that will cause an object to be created and move based on  the player cars speed. I want the object to have collision, but it goes through walls.

 

Here's what I've written:

 

At first, you're using opcode 0AB0:, so you have cleo installed but to make a cleo script you must add the cleo directive:

{$CLEO .cs}

But for now I'm assuming that it should be a thread of main.scm

 

 

The objects have different behavior depending to their settings in object.dat

Try the script below to see a working object when it was thrown.

It use the 3054, DYN_WREKING_BALL.

Then change the DYN_WREKING_BALL with your object and try again.

 

//{$CLEO .cs}//--everything behind two slashes will be ignored by compiling:Objectthrow_003A4: name_thread 'OTHROW':Objectthrow_10001: wait  0 ms00D6: if 00256: player $PLAYER_CHAR defined004D: jump_if_false @Objectthrow_1if0AB0:   key_pressed 8//-----------------------------press backspace  004D: jump_if_false @Objectthrow_10247: request_model 3054:Objectthrow_30001: wait  0 ms00D6: if  00248:   model 3054  available004D: jump_if_false @Objectthrow_304C4: create_coordinate [email protected] [email protected] [email protected] from_actor $PLAYER_ACTOR offset  0.0 5.0  0.00107: [email protected] = create_object 3054  at  [email protected] [email protected] [email protected]: set_object [email protected] mass_to 300.0 // float0908: set_object [email protected] turn_mass_to 30004D9: object [email protected] set_scripted_collision_check  10382: set_object [email protected] collision_detection  1wait  20000392: object [email protected] toggle_in_moving_list  10381: throw_object [email protected] distance 0.0  5.0  15.0wait  5000Object.Destroy([email protected])0249: release_model 30540002: jump @Objectthrow_1

Thanks for the help, by adding some code I was able to launch an object in front of the player. Now I would like to make it so the object keeps moving at a constant speed rather than fall to the ground, if anyone knows a way to do this I would be grateful.

 

Here's the code I'm using:

{$VERSION 3.1.0027}{$CLEO .cs}//-------------MAIN---------------thread 'OTHROW' :OTHROW_11wait 0 if   Player.Defined($PLAYER_CHAR)else_jump @OTHROW_11 if 0AB0:   key_pressed 103 else_jump @OTHROW_11 Model.Load(3065):OTHROW_51wait 0 if   Model.Available(3065)else_jump @OTHROW_51 04C4: store_coords_to [email protected] [email protected] [email protected] from_actor $PLAYER_ACTOR with_offset 0.0 5.0 0.0 [email protected] = Object.Create(3065, [email protected], [email protected], [email protected])Object.CollisionDetection([email protected]) = TrueObject.ToggleInMovingList([email protected]) = Truewait 0 [email protected] = Actor.Angle($PLAYER_ACTOR)[email protected] = 80.10819: [email protected] = actor $PLAYER_ACTOR distance_from_ground02F6: [email protected] = sine [email protected] // (float) 02F7: [email protected] = cosine [email protected] // (float) 006B: [email protected] *= [email protected] // (float) 006B: [email protected] *= [email protected] // (float) [email protected] *= -1.0 [email protected] += 1.0 0381:  throw_object [email protected] velocity_in_direction [email protected] [email protected] [email protected] 0Model.Destroy(3065)jump @OTHROW_11 

 

 

Some of it was taken from the knife throwing mod.

Attach it to a car (which you should make invisible) and do Car.SetSpeedInstantly.

 

EDIT - The car should also be facing in the direction you want the object to go using 07C6. I don't know how that opcode works exactly though.

using a car as helper? don't know if that will be the best method

You found now the bball which have the best behavior for throwing and collision.

To give it more power for bumping cars needs to increase the mass and the multiplier

 

0906: set_object [email protected] mass_to 30000.0 // float

 

It have then also a gravity behavior in the gameworld and make a ballistic curve by throwing.

We can stretch the curve by adjusting the multiplier for the x/y parameter and the height parameter

 

[email protected] = 250.1//-- multiplier

 

 

0381:  throw_object [email protected] velocity_in_direction [email protected] [email protected] 5.0

 

 

In addition do you need to destroy the object after using or remove it's reference.

You may not spawn unlimited items without discharging from script

Model.Destroy(3065) release only the loaded file but not the object instance

You must use 0108: destroy_object [email protected] or 01C4: remove_references_to_object [email protected]

but set a wait of a few seconds before destroying otherwise the object won't do it's effect

Now, if you wonna do it in vehicle you must consider that the spawned object infront of the car can bump the own player_car

especially because the vehicle can have high speed

So get the model dimensions of the vehicle and add some units

Now you can also use 06A2: get_car [email protected] velocity to use the values for the object throwing

but it will be slow especially when the vehicle is standing

so add some floats and multiplicate it with some floats

I think the calculation with sin and cosin is the better solution

Remove the comments and change the local vars in opcode 0381: to change the throw calculation with the sin/cosin method

Thank you ZAZ it works great, but there is one last thing that I don't know how to do. I need the object to stay on the ground, but still be moving, and be able to go over hills and ramps without launching into the air.

you wonna make a cruise missile, that's very difficult

[Ninjor]

If it's too much for you to do then I'm okay with that, but could you point me in the right direction?

[Deji]

I think there's a function for getting the Y angle of any point, but I'm unable to find it at the moment

 

 

Maybe this does the same?

 

0604: get_Z_angle_for_point [email protected] [email protected] store_to [email protected]

]

 

Seems odd that it would get the Z angle for a point, maybe it's misnamed. Use it and set the objects Y angle to the result.

[Ninjor]

Thank you for the help, though I have a problem. I don't know how to set the Y angle, because I can't find an opcode to do it.

 

EDIT: Nevermind, I misunderstood.

we talked about 0604: half year ago: Unsine and Uncosine

 

Today I found 080A: get_object [email protected] spoot 2 store_to [email protected] [email protected] [email protected] and I'm wondedring what it means

I don't know the word spoot

maybe it means spin?

I see only one chance, check the distance to ground and throw the object again

 

01BB: store_object [email protected] position_to [email protected] [email protected] [email protected]: [email protected] = ground_z_at [email protected] [email protected] [email protected]: [email protected] -= [email protected] // (float)if0023:   1.5 > [email protected]: jump_if_false @CAROBJT_47 0381:  throw_object [email protected] velocity_in_direction [email protected] [email protected] 5.0

 

 

well, i think you don't want that the object flys endless so you will need a condition to find an end

normaly you would check if it collides

but then it will collide before the script can react because of low distance to ground because it's to fast

[Deji]

Oh yes, I remember the use for the opcode now. In fact I've been using it loads, but the context of what I was looking for confused me. If that opcode hadn't already been named to that for so long, I'd rename it "asin" or something

 

I think spoot is something to do with the corners of an object, or more precisely, it's corners and edges as a cube... Spoot isn't really the most useful word for it. It's not even googlable.

 

 

Still, unless I can find the Ground Y Angle Function, I doubt there's any easy way of going about this. I'm really surprised I couldn't find it when searching
