Development questions

[RICCIARDI-Adrien]

Hello all,

Below are some questions I'm asking to the OpenTomb developers :

• I'm trying to implement TR2 secrets picking, but I can't figure out how to make them "pickable".
• I'm also trying to create TR2 tiger state control (using TR1 lion as model). Where could I find tiger animations values (like TR_ANIMATION_LION_XXX from state_control_lion.h) ?
• Is the repository bin directory really useful ? Can we remove it ?
• How to add Lara weapons muzzle flashes ?
• How to add Lara weapons ricochets and blood splats ?
• Project roadmap seems a bit out of date, is there a lot of stuff remaining before issuing a fully playable TR1 alpha ?

I'm also trying to create TR2 tiger state control (using TR1 lion as model). Where could I find tiger animations values (like TR_ANIMATION_LION_XXX from state_control_lion.h) ?

The numbers are actually defined in level files themselves.

Is the repository bin directory really useful ? Can we remove it ?

I always do it locally. I think it's a mistake to use git for binary blobs unless it's a separate repository. Otherwise it puts a burden on developers to waste their disk space without purpose.

Project roadmap seems a bit out of date, is there a lot of stuff remaining before issuing a fully playable TR1 alpha ?

See #91 and #417. But this is just my POV.

Other questions are in @TeslaRus competence.

• muzzle flashes, blood splats: calculate positions of effects, add sprites; sprites are partially implemented (bushes, grass in TR1); to find models, sprites use model view regime (y key);
• roadmap is old - I have no time and wishes to update it now;
• bin may be deleted;
• ricochets and blood splats - use ray test to find effect position, play sound, show sprite.

Thank you both for your quick replies. How to make a secret pickable like a medipack or ammo ? I will search in TRosettaStone for documentation about enemies animations format and location in level files.

It's not necessary. You can use OT model debug view as TeslaRus suggested.

Thank you, I didn't understand. Model debug view is a great tool.

Is there a way to teleport Lara to a specific map location ?

entitySetPos(id, x, y, z, ax, ay, az) see src/script folder and functions

Thank you. I added a more or less working Tomb Raider 2 tiger. When it dies, its body slips on the floor and goes out of the map. Have you an idea about the cause ?

dead state, may be physics disabling and make dynamic is wrong... try to see wolf / tiger dead state in script

[RICCIARDI-Adrien]

Ok, thanks.

I'm thinking about "dynamic" sprites architecture (a better name can be found), which would be muzzle flashes, blood splats, explosions flashes and all sprites that are not static in a room like grass.

• What do you think about using a list in Render.cpp that would contain all the dynamic sprites to display, their world coordinates and how many frames remains before their are removed from the list ? Later sprites animation could be added.
• Does someone know if there are sprites that must be "attached" to a moving object, which means that sprite world coordinates must be updated ?

Happy new year ! Do you think that pull request #597 can be merged or some work is needed ?
