How to shoot/spawn gasoline?

[0xsatoshi]

Like the gas from the jerrycan.

 

Is it classified under explosion/fire? I have searched for it but couldn't find anything obvious.

easy:

GRAPHICS::ADD_PETROL_DECAL(x, y, z, 1.5f, 2f, 1f);

 

position should be on ground level, 1.5f and 2f seems to be the width and height, 1f may be the transparency, not sure

GRAPHICS::ADD_PETROL_DECAL(x, y, z, 1.5f, 2f, 1f);

even though that is graphics, it still has the same effect as gasoline?

 

i will try it now.

 

EDIT: i cannot get it to work.

yes man, graphics dont means 2d draw

show me your code, including the position that you are using

just GRAPHICS::ADD_PETROL_DECAL(x, y, z, 1.5f, 2f, 1f);

 

with x,y,z being my current position. I have also tried an offset from my position. Do i need to pre render the gasoline?

[julionib]

did you tried the ground position or the player ped pos.? if im not wrong this and add_decal only work with the ground position of the position where you want the effect

can you show me a full example of it?

 

i tried the player position, I'm not sure what height the default player position is.

I'd suggest using the native, GAMEPLAY::GET_GROUND_Z_FOR_3D_COORD, and maybe ENTITY::GET_OFFSET_FROM_ENTITY_IN_WORLD_COORDS.

[julionib]

like Jsk2003 said, use the GET_GROUND_Z_FOR_3D_COORD to obtain the Z, this is how i did in one of my tests (vb.net but you may understand)

        Dim tmpPos As Vector3 = Game.Player.Character.Position        Dim tmpRes As Native.OutputArgument = New Native.OutputArgument        Native.Function.Call(Native.Hash.GET_GROUND_Z_FOR_3D_COORD, tmpPos.X, tmpPos.Y, tmpPos.Z, tmpRes)        tmpPos.Z = tmpRes.GetResult(Of Double)()        Native.Function.Call(Native.Hash.ADD_PETROL_DECAL, tmpPos.X, tmpPos.Y, tmpPos.Z, 1.0, 1.0, 1.0)

for your language the GET_GROUND_Z_FOR_3D_COORD may be used like this:

double *tmpRes

GRAPHICS::GET_GROUND_Z_FOR_3D_COORD(tmpPos.X, tmpPos.Y, tmpPos.Z, &tmpRes)

something like that, because the last param must be a pointer to a double/float
