From: Matthew Wong itsmattkc@gmail.com
Implement functions used by some games (notably LEGO Island) for determining which 3D object in a scene was clicked by the mouse cursor. Fighting Steel also uses this function for mouse over. Previous stubs would cause LEGO Island to crash upon any click and Fighting Steel to crash on game start. A patch posted years ago on the bug thread provided the minimum functionality to prevent crashes, but still rendered large portions of the game inaccessible without them implemented correctly.
Picking has been implemented by adding a "pick mode" in d3d_execute_buffer_execute() which skips any drawing functions leaving just the vertex processing. Adds click tests for each triangle when in pick mode for creating an array of D3DPICKRECORDs.
Stress testing reveals this patch's Pick() implementation may have slight inaccuracies to the original function; occasionally pixels right on triangle edges result in successful picks when they don't with the original function (and vice versa). It may be some sort of floating point rounding error or other algorithm difference that would be difficult to determine without seeing the original code. In practice, I believe this inaccuracy is so negligible that it won't produce any undesirable results for the user.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=10729 Signed-off-by: Matthew Wong itsmattkc@gmail.com Signed-off-by: Myah Caron qsniyg@protonmail.com --- v4: Don't check "count" variable as windows doesn't do this (according to tests)
Matthew's original patch is available here: https://www.winehq.org/pipermail/wine-devel/2019-August/149695.html.
This version addresses the corrections Stefan pointed out here: https://www.winehq.org/pipermail/wine-devel/2019-November/154023.html.
I've removed the "Add a" paragraphs from the commit message, primarily because the first one is now inaccurate due to the corrections.
The only comment I have (purposefully) not addressed is the last one referring to the corner case. This is because I know next to nothing about ddraw, and I don't have a testing machine on-hand either (only a VM). This also means that the new tests I have added are entirely untested on a native machine, so I'll have to rely on Marvin.
Regarding this comment:
The other question - to be answered by extending the test - is which count is used here. Should you copy all pick records in the device, or *count pick records, or whichever is smaller, or return an error if *count < device->pick_record_count.
I have added rec_count = 0 for the following to explicitly test for this:
rec_count = 0; hr = IDirect3DDevice_GetPickRecords(device, &rec_count, NULL);
However, since rec_count should have already been set to 0 if the previous GetPickRecords test passed, I believe this means that the inputted count variable is ignored by GetPickRecords.
