Ability to detect surface types
mikecnr opened this issue · 1 comments
Hi I'd like to request a feature to be added if it's possible. Can we please have the ability to detect the surface type that the casted ray hits? We currently get informed about the model, but the collision data holds information about the surface types too, no? Can this information be passed to PAWN by the plugin?
Obviously the game knows what surface type you are on for bullet hits and footstep sounds. It's part of the collision data.

For a use case example, I want to be able to detect when a player is standing on grass which will allow them to plant drugs.
Can you please let me know if and when this could potentially be added? Thank you.
There is a potential, surface information can be extracted from the .col file.

https://forum.mtasa.com/topic/119808-collisions/ - this one lists the different "materials".
Data from both surfaud.dat and surfinfo.dat may be useful for some things too, like determining if the surface is grass or metal.
Changes needed in Wizard:
- https://github.com/Pottus/ColAndreas/blob/master/WizardApp/src/ColManager.cpp
- Lines with
// Skip surface datacomment are where the surface data (TSurfacein the gtamods link above) is skipped.
- Lines with
- https://github.com/Pottus/ColAndreas/blob/master/WizardApp/include/BuildManager.h#L46
- These are the structs that will need 'surface material' variables.
Storing the data in the bullet memory is the more trivial part. Can be figured out though.
